Thanks for the video! You went more in depth than some of the other videos here. Using your method I found what seems like a dead/worn spot on my tps during the transition from idle position to wot. At about 25 - 35% from idle, measuring voltage only instead of the smooth progression of increasing value, it dropped down and then shot back up continuing like it should. I experienced this during my driving but never knew what caused the problem, it felt like I would lose power at a certain point during my acceleration but at cruising speed it would be ok. I replaced the tps and I don't have that issue anymore, again, thank you for the great video. It helps when things get pointed out and then I can test it for myself to find the problem. Mahalos!

I find your videos are some of the most informative without getting overly technical with information that we don't really need to know. This helped me diagnose my tps and move on to find the real problem. Thanks brother

So glad I found this video! Thank you! My intuition told me throttle position sensor initially, but advice from others was possible cma shaft sensor, Pulled codes that confirmed throttle positions sensor but not sure I can trust as this car was used when I bought it with a rebuilt hyped up racing motor. The wiring is sketchy. With that being said, having this knowledge lets me trouble shoot before buying the part! Car idles very rough when cold, and idle will increase then decrease on it's own. Slight acceleration issues as it doesn't immediately respond to pedal pressure. Runs better when warm. Idles great at higher speed. It does need exhaust running from the headers and back. These are racing headers so I'm unsure how much vacuum pressure plays a role. I have spark, but no start. In my research a no start is rare but possible. Any thoughts from others is graciously accepted :) Aware it could be timing, but want to start at the easiest point and work my way to that.

Check the throttle body to see if there is a gap. If there is a big gap, that can be caused by carbon or wear. It can cause high idle and codes. Replace it if it's worn. It may can throw codes about the TPS. Set the sensor for mid-range of specs.

@toyotoe3732 9 жыл бұрын

Great video. Thank you. You set the Multimeter to Resistance / Continuity to determine which wire is Ground. Therefore I take it that you cannot set the Multimeter to DC Volts to find the ground wire by connecting the red lead to the +ve battery terminal and using the -ve lead to find which of the 2 remaining wires is Ground ( I would expect to see 12V on the M/meter when finding the ground wire). I am curious to know if you can find the ground wire this way or not and if not, why? Or is Resistance / Continuity the only way to find the ground wire. Appreciate any feedback.

@myRatchets 9 жыл бұрын

You could do that, I just went with resistance so that you can also see the resistance reading of your grounding wire. Its also a little quicker since you dont have to switch the test lead on your battery :)

i had checked my TPS offline of course i put 5V supply , when i rotate the throttle the voltage at signal wire moves slowly up until i get ~4.5 voltage and back down when i slowly release the throttle.looks my tps is okay right? . but when i put back the TPS in the engine.I noticed that the signal does not increasing or not giving me a reading when we press on the gas pedal while the engine is running? so i still get hesitation . can you advise your comment here. thank

Following your video step by step trying to find a no spark issue on my truck. Both my tps and map sensor connectors have a little over 5 volts from 2 out of the 3 ports you probed trying to find the constant. I have no idea which one is the constant. I tested the map sensor connector just to see if maybe it was the connector. Now that I’m having the same issue in multiple connectors I’m curious if you know why I’d be getting 5 volts from more than one lead on the same connector? It seems to me that on both connectors my constant and signal wires are 5 volts and the ground may be the oddball with little to no voltage reading. I didn’t want to test resistance on either lead with 5 volts.

@davidlubin7389 2 жыл бұрын

Great video...like your style...straight and to the point! I have a '91 Camaro with an LS1 engine. It has a new throttle body with new IAC & TPS. PCM threw a P0122 code which is low TPS voltage which should be around 0.5v-1v at idle up to 5v at WOT. Voltmeter read 0.13v at idle (which explains the code) and only 3.94v at WOT. Since the TB was new, the manufacturer sent me a new TPS under warranty. When tested, it was perfect...just under 1v at idle and 4.95v at WOT. A day later, the new TPS was back to the same range (0.13v at idle & 3.94v at WOT) which threw the same code P0122. Any ideas as to what could cause this voltage drop? FYI, this is a newly swapped engine. I am at a point of "crank, no start" and am troubleshooting that as well. I do have voltage at injectors and coils, spark and 58psi of fuel at the rail.
