Q

I really like the idea of being able to test everything with a basic multi-meter. This is great.

You are the man Mr Wrench! It's like family showing me how to do this because you don't miss a thing. Like for family sake.

Very helpful video. Subbed! I will use this video to check out my dad's 2011 Altima. He said it went into limp mode driving to the supermarket this morning. I want to make sure he has a safe car to drive since he is 75.

The three wire hall effect sensors can still be bad if you're just measuring the changing voltage. You should carefully measure their static voltages as well. You should put the meter on DC volts and measure the signal wire with the ignition on, but without starting it. The voltage should be in one of two states, High state (5 or 12 volts) and Low state (0 volts). If you turn the motor by hand using a breaker bar on the crankshaft bolt it will cycle through these two states. The important thing here is that when it's in its low state, that it is very close to 0V. If you measure something like 0.120 volts, it means that your sensor is failing and should be replaced. If this happens, you will get random misfires. You should also make sure the voltage is reaching very close to the source voltage. Put one probe on the source wire and the other on the signal wire. The difference should be very small, like 0.02 volts. With these hall effect sensors, you can do this check with a new one without installing it and using that as a baseline. Simply connect it to the connector and make the same measurements; you could put something metal like a screwdriver near the sensor to put it into an activated state. I had this same problem myself. The engine ran great but I had random misfire codes pop up. The CPS signal looked good on an oscilloscope. After replacing the wires, plugs, coils, power transistor and even cleaning the carbon out of the ignition switch I was still having this intermittent problem. I took a closer look at the static voltages of the CPS and that was the problem. It was measuring 0.162v on the low state. The new one measured 0.026v.

Explained very well. Even an old school Holley carb guy and FI - ECU novice like me understood. Thank You!

Let me say you are extremely good at explaining things and in a reasonable amount of time. THANK YOU for not telling a story about your girlfriends dogs new trick when I went there to find out how to fix a flat. All made up however if you want to give information to assist people who may not know just do that. I think you are the first person that has been clear to the point and not confusing. I am very well knowledgeable on automotive troubleshooting and your information is good and anyone should be able to to follow you direction with ease as well you cover all angles. I don't see how anyone could not comprehend your info even more so if they watch a couple times if new to the work. I rarely leave any comments check my profile but I feel that even though you may know you are doing a great job keep it up and more so all the people who are on limited funds that you are helping is awesome!

I replaced my 2003 sprinter cam position sensor, works better than ever, I had crank but no start issues when the van was hot. $20 part with only 2 bolts.

Excellent info & teaching skills! Love your videos. Thank you so much for sharing your talents & conveying in such an easy to understand way for us laymen. Much appreciated by all!

thanks! i recently put in a NEW (but bad) CKP sensor and its apparently shorted internally- screwing up my fuel level gauge, ignition coil/ignitor(?) and setting off a host of other selonoids- et al! I cleaned all grounds, rebuilt my fuse box, new ECU, cleaned everything........no changes UNTIL i just now decided to swap back in the old CKP sensor. All the electrical clicking, etc went away immediately and Im not going thru the KEY RELEARN process for the new ECU.

No nonsense off topic crap that I see on other videos... straight to the point and no BS... thank you sir! Awesome videos!!!

Love your videos man !!! Being a mechanic myself the only thing I seen that could be not right.... When you were showing continuity,, I'd you have a 18 gauge wire with say 41 strands of wire in it, if 40 of those wires are broke or curroded your multimeter will show continuity. But will not carry enough current to operate the sensor. Need to show testing the wire with a couple Amp test light, depending on the circuit. Should make a video about load testing wires 👌

Perfect!!! straight to the point with no long drawn out pointless/useless spiel. You do some great videos, thanks

Great info. But when these sensors warm up, can be a fail. Do you recommend a mileage replace for these parts, b/c lets face it, nothing lasts forever

Each used car I get and need help, your videos get me through it, and the advice is good on any model. Thanks for the lessons.

To add a bit, if you have an older engine (say 1995 to 2010) with a coil-pack instead of an individual coil for each cylinder, then likely 2 cylinders share a coil. That is the "wasted spark" system where the spark plug fires on both the compression and exhaust stroke. If such wasted-spark, then the ignition system (spark) doesn't use the camshaft signal. The camshaft signal is only used to synch the fuel injectors to the intake valve openings, for lower emissions around idle. Of course such synching doesn't help at higher throttle since the injectors are spraying much longer and while the intake valve is closed. In such engines, the camshaft signal shouldn't be required for the engine to run well (just not optimal idle emissions), but that doesn't mean it will. I think some do and some don't. My 1996 2.4L & 2002 3.8L Chrysler engines die if I unplug the camshaft sensor, even though they have coil-packs and wasted-spark ignitions. Perhaps the designers were just being mean. Chrysler crank & cam sensor are 3-wire (Hall-effect) type, but powered by 8 VDC from the PCM.

Great video. I find that alot of problems can be made easier with a good diagnosis method, like yours :)

Thank you for your quick and precise videos, you have helped me in many issues.

This video is more helpful than I can say. I'm currently having a crank-no-start issue and by George i cannot figure it out. Time to do these tests. I've got the 3-wire - mitsu evo 7. Thanks RAW. God bless you.

Man i became auto mechanic watching your videos. You are the BOSS. Stay blessed.

Thank you.. You are a true subject matter expert. No guessing on a three wire.. Simple test.. wire, crank, scan the multimeter for a voltage signal.. Thank you.. Thank. Made it simple.. Have a great day..

Great video man. Way to explain the volt meter function. What if your engine is running fine then shuts off. After about 5 minutes it fires back up with no issues. But will repeat. I've already replaced the ignition module to no effect. This is a 2.5L Ford 4 cylinder

👌you as a teacher is incredibly easy to learn your methods; thanks 😁👍

the picture quality on this video is excellent

the best i have seen, and i been working on cars most of my life,thank you

Yes very informative video, I am replacing a sensor I bought today but now I will test both the ones in my porsche first

I was told that my CPS is possibly failing.. But here is my sittuation. There is no check engine light and the car starts fine but has rough idling in the heat or after the 1st trip? So if you drive in the morning to get gas there is no issues, but after you start up your car again (2nd trip) it starts idling low or bad. I have an AC adapter that reads voltage and at stops/red lights it drops below 12v.

So the second sensor he tests, when he puts the paperclips on it are we assuming he plugs the sensor back into the car but doesn’t connect the pins to the wiring harnesses since he has them hooked up to his tester unit? Or does he hook it up to both his tester unit and the cars wiring harness?

Great expansion on the subject I am now much wiser on this matter Thank You

Hello friend, good tip, maybe you have time to explain me this, he did the test to find the negative wire on the connector by using a multimeter. The setting was Ohms but he had the ignition switch ON also he hooked up the black lead to the battery post negative side, is that safe and correct, a friend long time taught me the correct way to find resistance but everything has to be OFF no source of power, am I wrong the way I had learnt, please break it down for me thanks.

If I could have understood anything you said that may have been a helpful video

If I am not understanding correctly please let me know but I believe the testing that you are trying to achieve is testing the input voltage make sure the ground is good and then also the signal. But is there a way I can test the sensor by itself is there a resistance test I can do on it perhaps test on one of the terminals can I jump the terminals and should it read anything with the connector unplugged?

Great video. I've been trying to fix my Tahoe that has p0336 error code and have watch all you videos to try to help. I've replaced the sensor, wiring, control module for coil, and the coil and still can't get any spark. Something odd is going on because I have power to all different components but its like the sensor is not able to read the signal when the metal cog/notch rotates past inside the timing cover.

Great video! I'd like to add that some crank sensors with produce voltage and can still be faulty if it is not being pulled all the way to ground, but you would need a scope to see that, cheers!

Great description on how to test the CPS.. thanks!

Like your Excellent Lessons :+) I recently got P0339 HONDA CKP SENSOR A CIRCUIT INTERMITTENT on my 2008 4cyl Honda Accord. ... My INNOVA OBD2 scanner also pulled a 10 second BATTERY Monitor scan test resulting in 11.84 VOLTS (at ECM vs 12.5v at my battery terminals) ... while saying: "BELOW ACCEPTABLE LIMITS". ... I believe my small 4 cylinder Napa battery has been reading marginally lower voltage for a couple years plus (& possibly the biggest source of my problem). I also believe some higher end batteries of same small size would retain higher voltage. My Choice now is: I am going up a size to the 24F larger size battery (spec 6 cylinder Accords) in AGM format as my best shot for a long term fix. I lost Engine torque when that code tripped. ... Erasing that code with my Innova scanner after study resulted in no more problems or codes returning (so far/ even though my 24F AGM battery order in progress makes that a near future project). I also intend to remove my Crank Shaft Sensor's plug and spay contact cleaner. ... My two cents as a past mechanic shop owner who still like doing all my own wrenching :+)

Helpful video, but what if you have both codes, which happened to my sons 2003 Mitsubishi evo. I have heard that a bad alternator diode, or even a weak battery could be the cause?

2006 Impala LT 3.9. The sensor that is on my car is plastic( the part that goes into the hole on the engine).This is like the first one you showed on your video. It also has a small rubber grommet. When I put the sensor in the hole and tighten it, it's still a little wabbly. Will that affect it's performance? Awesome video. Thanks so much.

If you change these sensors, do you have to do a re-learn procedure on the car? I have a 2008 Saturn Vue (3.6L). If you do have to re-learn, can it be done by a DIYer? Or is it something that a dealer needs to do with specialized equipment?
