    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!

    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.

  • @paulromsky9527
    @paulromsky9527 2 месяца назад

    Great video gave you a like. One thing to check: Once you see the TPS has correct and smooth voltage and operation, make sure that voltage signal is getting back to the ECU. If there is a break in the wire (mice like to chew on wires) or corroded contacts, the ECU won't see the TPS voltage and that causes all sorts of problems, but modern ECUs may throw an Error Code for that condition.

    I have the new connector and Tps but my existing wire is a small gage the new connector wiring is at least double thickness.
    So I decided to see if I could find if it anyone else ran into this?

    I have a 1996 Volvo 850T5 that stalled after code P0120. Almost got rear ended by a Mack Truck on the NJ turnpike! I changed the TPS twice. I also thought maybe the ECU was defective, so I changed that also.I cleaned the Throttle body with throttle body cleaner.. It seems that after about 25 miles the car stalls, I clear the code and then it runs for another 25 miles, until it stalls again and the code comes back. Thank you for your great Videos.

    @martystevens8357 7 лет назад +2

    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.

    My 1993 F 150 started idling way to high ( no tach but probably 1400RPM ). I unplugged the TPS and the idle went to normal. I drove it around the block with it unhooked and it actually drove ok with it disconnected (?!). I take it that I need to replace the TPS but it seems crazy that it idles and accelerates pretty decent with it not hooked up.

    @toyotoe3732 10 лет назад +3

    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
      @myRatchets  10 лет назад +1

      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 :)

    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.

    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. Thank you!

    could you use a test light connected to negative of the battery and back probe each wire and see which is ground and swap the test light to positive of the battery to find out the feed wire.Using multimeter you could back probe each wire on back of the connector with out disconnect seeing where is ground,power feed,and signal wire.You did a good video keeping going.
