This guy is the master. I love the way he explains everything. His words let you know he really becomes one with the systems he's testing. Almost as if he flies inside the damn electronics and analyses from within. I bow to his superior knowledge. He's the reason I am a mobile mechanic. 2 years studying and with his lessons I felt comfident enough to go out there and charge. Not bad at auto electrics now and its Paul I have to thank entirely. 11/10 dude.
I never get tire of watching your videos , when I watch it again I realized i missed or I did not absorb some thing, you're awesome teacher hard worker to dig to the root of the cause keep it up.
My Subaru has the same symptoms described in the video. I've been suspecting the TPS. Surging idle, high idle, low idle, wandering idle, poor acceleration; then it runs perfect. Sometimes I shut it off and restart it and then it runs perfect. I'll test it with a DVOM. Great video and great explanations, by the way. Wire harness integrity test was a plus.
This video helped me identify the problem on my 1g GSX! I wasn't sure if the tps was at fault until I watched your video and had the exact same symptoms. I didn't think to do the snap throttle test! Thank you!!!!!
I'm glad I came across this video. For the past few days I've been trying to find the right accessories to plug into DLC of a 1994 Mitsubishi 3000GT. No need now for the keyed adapter or Personality Key K7A. Saves me about $100.
Thanks to your videos I have a 2001 Mustang that runs like new..Since changing the TPS First time I have ran it was this morning. 50 plus miles. Passing gear was great and it didn't mess up at all downshifting out of over drive. Nor has it accelerated on it's own lol. - Now if I can make sure the coils are good with the multi-meter ill be happy. Two primary coils read 1.6 an the last was 1.0. Not sure if this is normal. Haven't checked the secondaries yet. Got to stop this header leak on the drivers side an hopefully it will stop the hesitation some more even. :) You are the man !
The ohmmeter is only good sometimes. If 1.6 is your spec, then I do not like the 1.0 coil, but one of your 1.6 ohm coils could still be bad. In other words if it tests good it could still be bad, if it tests bad it's bad. Make sense? Use Mode 6 on your OBD-II scanner to ID which cylinder is misfiring. I think it is test ID $53? I have some videos on this I show it here czcams.com/video/6kvYjYT1_mM/video.html Thanks so much! It is always a pleasure to help someone who can help themselves and are not just looking for silver bullet fixes. Or what part to try next.
Thanks for this video.! I have run into a simular isue after swapping ecu. Is there a way. Or maybe do you have a video how to do this with a old school multi meter.?
Paul thanks for uploading this, ive a vauxhall astra doing the same thing so this video helped me confirm it. I was wondering if you could upload a video on CAN? my friend has a 1999 Volkswagen Passat 1.9tdi automatic (I mostly work on diesels). When I scan the car with VAGCOM I get fault codes from modules on the car that there is no communication with the PCM and the PCM doesnt even come up on the scan. I found the problem is 7.8 Mega ohms of resistance between the CAN wires
I recently installed new tps on 92 ls400. but it's in such a bad spot for t pins how would I go about adjusting it to proper position I tried just using idle rpm with and without ac. it's obd 1. any suggestions? great videos I have been watching your great videos for awhile and it has definitely helped me get better at diagnosing my vehicles. thanks.
Hi Paul I just got a call for 91 Mitsubishi 300 with the check engine light on, I will use your video to get the code, I think this will be great for test..
no, the yellow arrow is pointing toward the yellow crank signal. the one with the groups of four square waves. I see what your talking about though, guess I should have moved that arrow down a little
My application used your method and code 14 was present. However while doing the reference test with voltmeter key on enginge off, none of the 3 wires at TPS indicated the 5v open loop. Any suggestions why? And want to say thank you for the cobalt video. The way you conducted the whole thing made so much sense.
Thanks for videos Danner, i have same engine with same intake also same tps on my 1994 Hyundai sonata a/t ( 3 wires means not included idle position censor in tps), my 1st question is 0,57 is a standart voltage for this type tps? 2nd how can i get true position for Tps? i know its working good but its not set true position on there, I have shop manual but that just say " if its not on true position, you can see shift lock issue with A/T tranny." so if i set 0,57 mv on tps than mean is it ok?
I have a DRB-II with a super cartridge in it. I love whipping that out and getting a nice full set of data stream info off of old Chrysler vehicles. Never done it on a DSM car, though. I need the dlc adapter for it.
Hello, I have a question regarding TPS sensor. Is there any chance of opening the throttle body to get to the potentiometer and clean sensor contacts. Generally, can I make sensor to work properly with just cleaning contacts or is it better to change all unit? Thanks.
Paul, on page 22 of your book you have the green arrow pointing to the cam sensor and then you have the yellow arrow pointing to the green channel as the crank sensor.
If you are talking about an electronic throttle body, the motor circuit is a reverse polarity design. A scan tool with bi-directional controls and the ability to look at desired and actual commands is key in troubleshooting those.
I have Elsawin, Bosch ESI tronic, and autodata but none of these show a CAN diagram, I understand about terminating resistors but dont know were these would be located, it must be a bad connection or wire somewhere between the PCM and Gateway, but havn't a clue were the gateway is. Any light you could throw on terminating resistors and CAN would be awesome. Also I lost my login password for your ebook, do you know how I can find this again? Thanks Ben
Hello, I have a P1390 code on my 1997 Eagle Talon (non-turbo). Can anyone help? I recently swapped another motor 420A and it runs good, however, its sluggish at times when I want to accelerate.
Hey Paul,tested TPS on my 93 maxima,i got 8.3 volts on a signal wire and on a five volts reference wire,why is that? I experienced some hesitation when I accelerate then smooth out. I didn’t extract the code....
U can also use a buzzer from radioshack and touch each end to the points and count the buzzer sounds. Count the number of buzzes and search google for a list of the codes.
Gr8. Vid there. I am Trying to figure out an interment surging when at idle. I was thinking it could be. TPS or IAC . Recently throttle body was removed as part of valve cover gasket replacement 2001 maxima When it was all put back I got some strange idle and p0505 Found an air intake tube leak . And the p0505 never came back Then found a Sticky throttle and found a loose bolts for the throttle cable . Now I get some random idle rev up and down when sitting in park after maybe driving a bit and then sits idle if for like 3 mins ( like waiting for a pick up order) I have viewed live data on AD410 scanner and I see tps voltage moving and graph looks ok. I just haven’t been able to to get my scanner on it when it’s happening Ideas?

Except for the blinking CEL, that Chrysler concept is pretty much identical. If you were to probe the self test output and B+ you would get the exact same graph.
On some cars yes, on others no. The ECM uses a "minimum TPS voltage" number that is learned and is retained in memory. New cars will issue a relearn on every key cycle and older cars it would only rewrite when battery voltage is interrupted. Make sense?

thanks man. it is nice that you recognize that. not much negative posts going on here.
Very good info about the TPS. This issue relates to mine. Thank you so much.
This is my Talon! I have to thank Danner for helping me with my car. Also if anyone has a passion for cars or trucks, I would recommend going to RTI.
That's a very interesting method to check codes on that vehicle!
Thanks! Paul. Excellent video as usual.
@felplay vina cool, if you don't have a scope you can use an analog (needle type) voltmeter and count your sweeps
Great job troubleshooting this. You know you stuff for sure.

Hello, I have a question regarding TPS sensor. Is there any chance of opening the throttle body to get to the potentiometer and clean sensor contacts. Generally, can I make sensor to work properly with just cleaning contacts or is it better to change all unit? Thanks.
So if the voltage was monitored with the engine running,it would probably show the voltage fluctuating to low volts?
Paul, on page 22 of your book you have the green arrow pointing to the cam sensor and then you have the yellow arrow pointing to the green channel as the crank sensor.
how can I get this fix? should I just replace the TPS? how can I recharge the wires with the meter
Damn, is that time on the vantage correct?
I think I like the old Ford blinking check engine light method a bit more!
so the three wires on the connector was power, ground and signal?
If the TPS tested OK, how would you test for a bad throttle actuator motor (or solenoid) ?
If you are talking about an electronic throttle body, the motor circuit is a reverse polarity design. A scan tool with bi-directional controls and the ability to look at desired and actual commands is key in troubleshooting those.

how many wires are on your TPS? I believe on that year it is not a potentiometer but a switch. It has a WOT contact and an Idle contact. Not sure.
HOPE YOU WILL HAVE DONE THE UPDATE ON THE E-BOOK FOR NEW PURCHASE

I'm going to order the tps then I might do it at home, or maybe bring it in.
Do I have to reset the ECU after TPS replacement?
On some cars yes, on others no. The ECM uses a "minimum TPS voltage" number that is learned and is retained in memory. New cars will issue a relearn on every key cycle and older cars it would only rewrite when battery voltage is interrupted. Make sense?
Does it mean the ECM is still (even if I already changed the TPS) substituting until I remove the negative terminal of the battery?
Not substituting but using the old TPS minimum voltage signal. This can cause a very high idle speed among other things.
my 87 suzuki swift has 4 wires tho...
When they tell you the price, ask them "Does that include the Vaseline?"
It’s a three wires,TPS
I looked up the cost of a new sensor: $200 YIKES
I have the same kinda problem but long start and high idle when u trying to drive check my videos to understand better
Yeah tell me about it lol. This is my car.
