The Jam nut adjusts the throttle plate. Be careful when playing with that cos if you go out of the "range" of the accelerator position sensor the throttle will stop responding

The other (screw) is to set the maximum range of throttle movement (WOT and closed)

Will not idel while in gear or with A/C on.

Check your throttle body for a restricted or dirty throttle plate. Remove the air horn attachment from air filter to the intake throttle body. Inside that intake is the moveable throttle plate. Use a warm lightly soapy wash cloth to clean throttle plate and area free from soot. Then assemble and recheck your problem. If still an isse you will need to disassemble the iac motor from intake manifold and clean inside that area with throttle body cleaner. Those methods are a must before diagnsing further.

Tps location

The Throttle Position sensor (TPS) is a potentiometer that provides a voltage signal to the PCM that is directly proportional to the throttle plate position. The sensor is mounted on the side of the throttle body and is connected to the throttle plate shaft. The TPS monitors throttle plate movement and position, and transmits an appropriate electrical signal to the PCM. These signals are used by the PCM to adjust the air/fuel mixture, spark timing and EGR operation according to engine load at idle, part throttle, or full throttle. The TPS is not adjustable.

Location of tps on a 04 6cyclider jeep cherokee lardeo

TPS is always located on the end of the throttle plate shaft, it is attached by two torx screws on the throttle body. The same shaft is connected to the throttle cable, through the throttle body and plate and then into the tps.

How do I adjust the idle on a 2000 toyota tundra

This is all controlled by a computer, you are going to need to take it to a dealer, OR you can buy a tuner that will also control idle

Rough idle in reverse and drive

your best bet is to check the throttle body and throttle plate for excessive build up. Remove the air cleaner assemble and use a flash light to look into the throttle body and manually open the throttle plate by moving the linkage. if you see a bunch of black build up on the back of the plat and around the inside of the throttle body where the plate seats against it, spray some carb cleaner on a rag and wipe off what you can, if needed remove the throttle body and use a old tooth brush and carb cleaner. if the throttle body and plate look somewhat clean you might be in need of a tune up.

Throttle Position Sensor??

Sensor is attached with two torx screws on the throttle body. it is easily removed and is non adjustable. Be sure you engage the throttle plate shaft properly before tightening it up if unsure what it looks like, buy the new one first..

Where is throttle position sensor located on 2000 honda passport

Normally attached at opposite end of throttle linkage. Remove your air cleaner intake hose at throttle body, and observe throttle plate that opens & closes as you press accelerator, it will be at the end of that, on outside of housing.

Sticky gas pedal

it is a dirty throttle plate. $280 is an absolute ripoff for a cleaning, it is about 10-15 minutes of work. They are probably quoting replacing the throttle body which about a $150 part.

Got to Autozone and get "CRC Throttle Body Cleaner". Remove aire inlet hose at throttle body with a screwdriver. Spray a *small* bit onto throttle plate, use clean rag or qtips to remove gum/varnish. Spray pivots and also clean around perimeter of the plate. Take it to an independent mechanic if you are unsure of the procedure.
