Another bad ass informative 7.3 video! Thank you and kudos.

You’re the man, always love your videos

Thanks man for the great information it’s hard finding information on this damn bus luckily their is people like you

Been waiting for this one 🙌

Great information, as always. I appreciate these videos on the 7.3 as a continue to learn more about mine that I've hard for 1.5 years.

Best 7.3 information on the internet. Love your channel!!

That was very interesting, always learn something from your video's. Love how you show all the parts and where they belong, that is super helpful!

Great video thanks for the info

The Oil Sensor on the back of the HPOP Resevoir change smoothed my cold start idle and smoothed out trani shifting. Thanks. No more rumble! Doing the Exhaust Back Pressure sensor and pipe next.

This was fantastic! Didn't know I had a water temp sensor in my 2000 7.3 auto. Thank you for your attention to detail, speaking slowly and clearly enough to understand and with rewinding 100 times, and the great visuals.

Thanks. In the process of changing the engine wiring harness (per your recommendation in another video). 1997 auto, been looking 2 days for the sensor to mate with the left over connector near the CPS. Removed the alternator, etc., and couldn't find anything. Now I know. Thanks, again.

I have a 2000 7.3 I didn’t catch the part number for the temp sensor Beside that awesome video I’m learning a lot about my truck

Right at the end of the video you answered my question. I’ve tried two sensors: one from CarQuest and one from O’Reilly. Neither worked. I’ll go to a Ford dealer next. The original sensor reads middle of the gauge all the time. Soon as you turn the key, dead cold, it says it’s at perfect temp. The other two new ones shows cold all the time.

Just to bring this long rambling to a conclusion. I did use the EOT style "dy-1144" coolant sensor in my 2002 F350 7.3L 6spd manual (cab and chassis, door tag says: "Incomplete manufacturing" 09/2001). So for whatever reason, even though my truck is not a 2003- It still uses the EOT sensor; just like the Excursions and E-350. I drove around the block a few times, and it settled right to the middle of the gauge, just like it always did before and the heater was blowing warm like it did before. So I'm assuming it works. Thanks for all your info, I'm watching ALL your vidoes. Cheers.

On the pre-OBDII, how does one scan for codes and clear the codes? What are the recommended aftermarket gauges to add if we can't use a scan tool?

My temp gauge on the dash does not work but all of a sudden it starts to go up now but it’s my transmission that is overheating. I have to replace the rear seal bc it recently started leaking. So I thought that it was low and that’s why it was getting hot but when I check the dipstick it’s all over…

Hi, thanks for the video. I have a 2003 F250 7.3L and my temp gauge doesn't move much at all. Does the paperclip or grounding test work on 03's? Mine doesn't move when I try it. I put the paperclip in the plug that goes directly into the cluster and still get no movement. These gauges go all the way up when I initially turn the key then drop back down. I tried a junkyard cluster and get the same results. I tested the resistance of the gauge and the numbers all matched the trans temp readings also so that makes me think the gauge is within spec. I don't know where to go from here.

I did find out that there is a big difference between the temp sensor and temp sender. Because when i bought my 2000 excursion 7.3 the temp guage did not function at all and a temp sensor they gave me dont fix it , it needed to be temp sender on top of the water pump. Its been a while but correct me if im wrong on this

Had to replace injector cups, rebuilt injectors, oil change, flushed and flushed several times the coolant. Had coolant leveled out and started engine to burp the air with Auto Enginuity scanner attached, The coolant temp gauge on the scanner showed half temp after engine had warmed up, then showed 302 deg before going to 202 deg and staying there. Tested both temp sending unit wiring and lights/gauge but the one on the scanner is stuck at around 200 deg engine running or not. Cannot find info on what could be wrong. Service manual no help.

Hi- have a 94.5 manual trans, gauge not working, but ground out test pegs to max, so went and got and installed new MC sensor sw2328/f1sz10884a per video. Gauge still does not work (it’s all the way left/cold). The mc sensor read about 330ohm at room temp prior to install. Can you please suggest next steps?

My 97 standard the temp gauge barely comes off the cold maybe 1/4 even after a long drive for a couple of hours ! Any suggestions? I’ll try the grounding to see if it jumps to “H” if not should I change the other sensor out or just do both

Hello Clint, I have a 2001 7.3 excursion, ect reads normal till warm up then goes -130c every time. Checked wiring, replaced both ect and eot. Any ideas?

On a 97 the engine temp light came on but the motor is still cold and has plenty of coolant

I’m having shifting issues when I’m driving over 40mph. Shifting 3rd to 4th then back to 3rd, then back to 4th. Can you tell me if this is a Transmission Temp sensor issue? I just changed our transmission on our 2001 Ford E350 7.3 16 months ago. Thank you

I have a 2002 model and the automatic transmission has no visible sensor. Maybe under a valve body? Thanks.

Got an 03 7.3. Do you happen to have the part numbers for both sensors?

I have a 96 7.3 automatic. My in cab gauge does not move past the N in Normal. It will move from the C to the N but no further and my heater will not blow hot. The core is flushed and the vacuum line is repaired. I’ve heard it could be the sensor on the top of the water pump. Is this possible??

I got a 2001 truck and my gauge stay cool all the time which sensor do I need

@customworks or anyone… 95 obs 7.3 e4od automatic. I pulled my transmission pan and didn’t see a temperature sensor. Do they all have one?

hi sir . I have a 1998 shutle bus powerstroke 7.3. The temp needle goes full from the moment you turn the switch. I disconnected the temp sensor that is on the water pump and nothing happens, it remains full. I would really appreciate it if you give me an idea.

Navistar at it again for slight diferences, but I hope I'm wrong.

Mr Clint I sorry probably my issus with my 97 f250 7.3 is off topic with this. But I've have notice my truck that when it idles kinda ruff and stalls out like every 10 mins but I can turn it back on like nothing sometimes it also cranks a bit longer. I've noticed this only happens when I run a my ac? And sometimes misfire around 60 mph. I cant seem to find the problem I've change all the sensors cps icp and ipr. Hell even fuel filter and even neutral safety switch. Would appreciate it sir to know if you had ever know about a problem like this. Looking forward to see what the master mechanic of 7.3s has as answer to me. Thanks!!

Check you valve cover gasket connectors. The pigtails and connectors on the gasket themselves. Especially the passenger rear if it’s an OBS truck. You also need to take a look at the connection on the underside of the valve cover. Look for chafed wiring. It could be a lot of other things too, this is a common problem for that. If you did not replace the sensors with OEM that could another problem on top of your original problem

A few good questions there. I'd love to know those answers as well. Hope he sees these questions and can answer them.

I've got a strange issue going on with my 95 7.3 automatic. Been trying to figure it out for awhile now. Rough idle, engine vibration when cold. As the truck starts to warm up the vibration goes away but when it gets to operating temp the vibration comes back. The only time it doesn't vibrate is between the N and R on temp gauge. Feels like it's fuel or electrical related. Loss of power and fuel economy. No CEL All Motorcraft sensors Fuel pressure is 55 PSI Fuel tanks are clean Change oil ever 3,500mi Please help?

clean off check the color but usually the pump sensor is the same on the cover was a few model years when they changed from obd ports each sensor was different but very few but they will be dif colors

I've got a 2003 E450 cutaway and I dropped the transmission pan to change the temperature sensor but it looks like my transmission isn't the same. (Looks like a 4R100 or e4do) I'm getting crazy ECT temperatures when I use forscans dashboard, up to 500° then dropping down to 2° instantly and then climbing back up to a normal range. When I shut it off and start it back up it says ECT is over 300° but the EOT is normal. the temperature gauge stays in the normal range and I'm not getting any lights or codes but it's running like it's in limp mode after it warms up. Does this sound like a bad PCM or something else?

@@CUSTOMWORKS7.3PSD Thank you. From what I'm reading it looks like the temp sensor is integrated into the solenoid pack. It's a 4R100 (RFF81P-7006 CA on the case but it's been remanufactured) Do you know if they all use the same solenoid pack?

So do you mean they are using an "engine oil temp" sensor to run the temp gauge on the dash with actual oil temperature? Or are they simply putting the EOT into the water pump mounting hole, and using the EOT to read the temperature of the water? I'm just curious what you mean at (4:09). Also, what about 2002 model with 6 speed manual transmission? Everywhere I ask, I get a different answer. I just need the sensor that bolts into the top of the water pump, but I can't nail down which one it is. The one that was in my truck had the cone shaped tip with a white colored connector. I've found a few with the cone tip- but they all had the black plastic connector (not sure if that matters)... I ordered one on fleebay, and made sure it was a motorcraft. It was the cone shape tip with white connector (in the picture). But the one they sent me was actually the EOT- with the smooth round shaft and flared tip (like what is shown in your video for 2003). So I'm going to send it back, I guess. But even when I go to Oreilly's, they don't seem to know what they are talking about, and they don't even realize that there are two sensors. My question is. Can the EOT style work on a 2002 7.3L with zf 6 manual? or is it just for the 2003.. (again, the one in the water pump-- not the front cover). I'd rather just use it if it will work. But if I open it, I can't send it back... If it won't work, I guess I'll try what Oreilly's has, even though it has the black plastic connector, and not the white one that I used to have. (Is there any difference? as long as they both have the cone shaped tip, and are both motorcraft: does the color of the connector matter? Any help would be much appreciated thanks.

@@CUSTOMWORKS7.3PSD I did a little more digging. So the sensor on the water pump is (obviously) referred to as the ECT (engine coolant temp sensor). But the other sensor on the front cover (for manuals) is called the CHT (cylinder head temp) sensor, as far as I know. So that makes it easier when searching. Thanks again for the links.

@@CUSTOMWORKS7.3PSD Hear me out, I think you might find this interesting: (if not, I'm sorry to bother you again). I went out into my yard and luckily my broken sensor was still there where I threw it down. :).. so I wiped the 20 year old dirt off and somehow magically got the ultra small laser number on the side of my old sensor, and its: "F5AF-12A648-AB" and "1H20A" right underneath it. (brass cone tip) But an even more interesting thing is that: even though it is busted off from the brass threads. It's still intact and I can see the little sensor on the end of the little connecting bars (wires). So I ohm'd it out, and it reads around 30k ohms at room temp.. but if I hold the tip of the (exposed- broken away from the brass) sensor with my fingers- it will drop down to around 22k ohms. So it seems to still be working smoothly in the readings, or at least temperature does have an effect on it. So I was curious about the new sensor I still have, (which is the EOT I was wrongfully sent): (dy-1144) also says (3F1Z-12A648-A) on the package. (smooth brass shaft with flared tip) So I ohm it out through holes in the plastic package (without opening it), and it reads: around 28.4k ohms. So they are both in the same ball park. They are both supposed to be genuine Motorcraft parts as far as I know. It's in a Motorcraft package. If you're still with me and haven't lost interest (thank you)--- My question is: Are these the same EOT sensors that are used on the EOT that is on the back of the HPOP reservoir? Are they interchangeable? The reason I ask is because, on your dedicated EOT video, you show the resistance ranges to only be between 1k to 8k ohms. Are these sensors I have completely different possibly? Or is the "EOT" temp sensor actually different from the actual EOT oil sensor? So my ultimate question is: Do you think My original "broken" sensor is a real Ford part? Or was the correct original part rather? It was certainly working before I broke it. (F5AF-12A648-AB) And do you think the new EOT sensor should work? Since they have very similar resistances? Even though it's not the same as the resistances you give on your EOT video. I checked the tag on my door; it says: "Manufactured 09/ 01" -- But my title says it's a 2002. So I suppose it was built late enough in the year to be considered a 2002. But it's definitively NOT a 2003, apparently. Although it says "incomplete manufacturing" on the door tag. So it was an XL cab and chassis when it was built, plus it has the 6 spd manual 4x4, so it's a bit of a unicorn oddball I guess; not sure if that would have a weird sensor or not. It doesn't even have tilt wheel or cruise control, and I had to put a flatbed on it when I bought it used. I know the E350 vans have a different sensor for some reason?? with the same 7.3L engine. Could mine be considered "utility" like the Econline E350, since it's a cab and chassis? Everywhere I check, it says that this new part shouldn't fit my truck-- But I've crossed a few places now that says it's a direct replacement for the senor that I have. So was my sensor not the original maybe? I have an xtool D8- I guess I can plug it in and see if there is anything weird that makes the computer think it's not an F350. (sorry to ramble, I'm just dumping all the info I know). To clarify, when I cross reference my broken" ect number on fordparts" site, it says that the sensor should NOT be in my truck. It shows it in the Excursion and E350, but NOT my F350, even though it was obviously in there and working as intended. :) .. It's insane I crossed a write up on a site: "deadheaddiesel" dot com.. titled: "7.3 eot sensor symptoms" I'll just copy and paste it in a reply below this if you want to read through it (or you can probably just google it). He seems to have found the lineage and history of all the sensors (mostly anyway). Again, any help would be super appreciated. It really shouldn't be this difficult, but apparently it is. :) If you have any VIN info that is certainly welcome. (for example, before 2xxxxxx VIN it should be XYZ, and after that VIN, it should be 123, etc..) Thanks again. Cheers.

@@CUSTOMWORKS7.3PSD Hear is the info from "deadheaddiesel: 7.3 Engine Oil Temp Sensor Part Numbers After an exhaustive search I’ve found that there are 3 distinctly different-looking parts that are represented to be 7.3 EOT sensors. All of them also cross reference to 7.3 ECT (Engine Coolant Temperature) sensors. 7.3 EOT sensor (Old - ROUND connector) Pre 1996 - 7.3 EOT sensor part number: WT5058 ON eBAY (ROUND Connector) - Cross references to SU201, 36407, WT5058, 5S1140, 9362, 4H2 Retrofitting 1994-1995 EOT to the new style sensor 1994 and 1995 old style round connector 7.3 EOT sensors can be switched to the new style (Rectangular) ones below. (REQUIRES Pigtail Replacement: SEE “Wiring Harness” section BELOW) 7.3 EOT sensor (NEW - Rectangular Style Connectors) 1994-2003 - Superseded replacement 7.3 EOT Part Number - F5AZ12A648A or F5AZ12A648AB (Which most often comes up described as the 7.3 Engine Coolant Temp Sensor, but is used interchangeably as a 7.3 EOT sensor) However, a quick check on fordparts" and their system converts that part number to… 1994-2003 - Ford OEM superseded replacement 7.3 EOT Part Number - 3F1Z12A648A (Ford calls it a “SENDER ASY”) And finally… 1994-2003 - Alliant Power has a superseded replacement 7.3 EOT Sensor-Part number: AP63436. It replaces - F5AZ12A648AB, 3F1Z12A648A, DY961, DY1144 as a direct replacement for them all. After more research than I like to… Okay, that’s not true-I love researching this stuff. Anyway, the two new parts are represented as being interchangeable. In fact, there are several forum threads where DIY 7.3 owners swap the ECT and EOT sensors back and forth, attempting to troubleshoot a 7.3 EOT problem. 7.3 EOT Sensor - AP63436, 3F1Z12A648A 7.3 EOT/ECT Sensor - F5AZ12A648AB My suggestion - remove your 7.3 engine oil temp sensor, see which one it is, and replace it with the same one. If you’re not that motivated or you want to upgrade to one of the new sensors, it shouldn’t matter which one you use. But for pete’s sake, don’t just unplug it…

( perhaps you meant to cover those two sensor parts (shown) to encompass the wider range of model years (94.5- 12/98) and it was a misprint when you showed the 94-97 designation only?)
