Out of all the videos on how to adjust a TPS, this is the only one that actually explains what to do

Just wanted to let you know you saved me hundreds of dollars and a great deal of time with this video. I acquired an 89 c1500 with a recently rebuilt 5.7 after it rear ended me on the hwy. After replacing all the crushed body panels and related pieces, I couldn't get the rough idle and check engine light under control. I was prepared to start shotgunning replacement parts and sensors to see if that would help. I watched your video and thought to myself "heck, I've got a multimeter". 5 minutes to adjust the TPS...no check engine light and idles smooth as silk. Thanks guys!

I think I am going to have to reprogram mine because I didn't even consider that cleaning the throttle body would be affected. There are some great videos out there and this is one of them! Thank you sir!

At first i was really starting to get pissed off at this video. But then you guys actually put out good information. And the commenting guidelines earned you a subscribe. Thank you!

Great video. Explained it clearly. I would have liked to have seen the voltage lower or higher so you could have adjusted the TPS. But this is a professional shop so I understand.

I've been looking for a video like this for a year on how to read and use the meter to read the throttle position thanks so much !

All the information I needed and none I didn’t. Awesome work dudes!

About the only video that is simple and straight forward !!

Thank you for this video. it fixed my idle problems ive been having for over a year

Okayyyyy learning new things every day appreciate it John

I wish yall had shown how to do the actual adjustments if not getting the needed readings. That’s what I’m needing and been looking for and cannot find instructions on anywhere. This was helpful but need more data on the calibration. Thank you!

Thank You. Very helpful info. Just replaced my whole throttle body with sensor and didn't calibrate it. I have been having issues with the car running rough and some OBD2 error codes. Now I'm going to calibrate it so maybe that might help fix it. I haven't been able to figure out what has been wrong with it so it's been in my garage for quite awhile. Also I had some issues with the wiring. Thanks again for all the info.😊

Thank you for the exact voltage value.

Yeah. You are my go to guys from now on.

Great video the only that tells exactly what to do Thank you

Back in the day on my mustang 5.0 Fox body the magazine editor's recommended using small safety pins carefully pierced through the wiring with alligator clips on your DVM. These types of maintenance tips are what can give you an advantage at the drag strip.

Aye thanks for teaching me a new trick. Quicker than programming TBH.

I ported and polished my Throttle body! On my Australian V6 version of the American Buick based engine. 3.8 litre ecotec. I had a hunting on idle. As in revs were going up and down,then settled. I just lightly adjusted the throttle cable to remove any slack. I replaced a hose with silicone hose in the performance type on my CAI going from my TB to MAF sensor. Strangely it's not hunting anymore! Maybe my old hose had a vacuum leak? Also my 4L60E transmission doesn't slip like it randomly would do. I'm gonna back probe like you did. Top video! It took forever to find a proper tutorial on TPS SENSOR Setting! Subbed and liked. Cheers from Australia 🙂👍👍👍

Thanks momma!

search around videos, this is the best one I think. Now I am relaxed because you mentioned "aftermarket" won't be perfect, so, I am not looking for perfect one online now. By the end, the younger person explained further the key point: the full closed throttle is looking for 0.45 V, this is sooo cut the chase...

I found the little block inside the sensor that seats onto the fork to turn the throttle to be unaligned. By putting it back in the slot it instantly fixed my voltage issue. Could be the tps was put in wrong if it worked fine many times recently before.

I have a certificate in basic electronics and you can buy multimeter test leads that are pin ends from fluke, you need to be patient because the are some of the thinest wires used, I'd put it down near the plastic and patiently wait for a reading.

Great video guys. What's next if the TPS is good ?

Super helpful and for all cars 0.456?

I always scribe a crisp clean deep line on my old sensor old throttle body while still in place haven't had any issues just line up the marks and done

Based off what your friend said if I installed a new tps and calibrated it to .45 volts and runs a little hesitant at times I should re calibrate it? Maybe go up in voltage?

Hi. I've got a 2003 Montero Limited 3.8L. Twice so far (1,000 miles apart) mine has gone into a condition where it will not accelerate. It idles and starts fine, but will not go over 40mph on level road, and takes a long time to get to that speed (severel minutes). It will be fine one moment and then begin this malfunction in the middle of driving it, in town or on interstate. I do have a TPS sensor code (P2135) but also cam and crankshaft sensors codes. The timing system is fine and it doesn't jerk or do anything strange except refuse to accelerate. I can turn it off and after 20 minutes it will operate fine again. Is the the TPS sensor getting hot and then it fails?

So can I do this to check if my throttle body is failing on my stock b20 ?

Dont forget to check for dead spots as you sweep from .45 to 5v, i wastching a video and that was his problem it didnt go smoothly up, it went down before it went up again. The TPS is basically a potentimenter with a whiper blade that makes contact, sometimes the contact isnt good or gets corroded and you have a dead spot. I got a TPS error code on mine but no symptoms like rough idiling or low power. Except when i took it on the highway the first time, it did feel like i was pressing the pedal more then i should have... i thought this was in my head trying to be cautious with the car on the highway for the first time but maybe it is a dead spot that isnt noticable until highway speeds. I just got the car so not entirely famliar with it but noticed it was good on gas in the city, good pep too but didnt get much better milage on my highway trip which had me puzzled. Also noticeds the air injection pump relay and fuse were missing, so figured it was attributed to that, until i saw the TPS error code. Maybe it isnt a TPS issue but related the air injection pump basically being shut off. Funny thing is when i try to find what kind of relay it is(to find a replacement), all the videos of my car showing the fuse box have it missing as well, maybe its not critical... i heard it was for emissions, but also heard its for better fuel efficiencey. Anyway a slow sweep of the TPS will reveal for sure. Also heard a fast sweep can cause damage since it generates electricty. Probably being paranoid there but better safe then sorry.

Hey man so the lowest voltage i can get on mine is .72V. Now before i replaced the tps I remember trying to adjust the throttle cable to compensate for the idle issues, but forgot the ECU will do the things to attempmt a stable idle. Could i just have the throttle cable too tight causing the higher readings of .72 - 5.2V seeing that the tps is what monitors the butterfly?

correct me if I'm wrong but OEM spec says .5V full closed and between 4~4.5V full open, all depending on the ECU your using

You shouldn't strip any wire insulation away, you are opening up the wire to corrosion or you might have a heavy hand and cut some to the wires. I would like this video if you had just used a paperclip inserted into the connector.
