How to Calibrate Throttle Position Sensor Using a Multimeter (Set TPS)

This is the easiest and fastest way to set and test your throttle position sensor. Why do you need to calibrate your TPS? Well the ECU needs to know the position of the throttle so it can determine what it needs to do with ignition timing and fuel injector duration. It will literally impact the way your car drives. This is easily one of the most important steps to verifying that your car is going to perform reliably on the dyno and just driving around town. Hope this video helps.

Forgot to mention that the correct way to test the voltage is to back probe the connector. Not cutting the insulation.

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!

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!

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

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.

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

[j.s.]

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!

[darr]

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.😊

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 !

[sonzaun]

learning new things every day appreciate it John

[johnnyperez]

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

[Dhi-feeu]

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.

[miguelmagallanes]

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?

[simpleclean]

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 🙂👍👍👍

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.

[grandinfinite]

So, if the numbers are not within that range, do you rotate the sensor to and fro? Thanks.

[Fearisthemindkiller]

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

[theycallmekensington]

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