I replaced it and the ideling problem went away but it is not shifting properly (it doesnt shift to 2nd until 6000 rpm andd hasnt sifted to drive at all) Is it possible that the new tps vave is faulty? The check engine lite is on and the code says it is the tps valve is there something I am missing?

SOURCE: is it possible to adjust a throttle position sensor on a 2000 montero sport?

when your vehical throws a code and you replace the defective part, you must clear the code or the ecm will still recognize it as an active code.

Hi, Take a little time to check all earth mounts,There are some fine earthwires under the looms running from air intake if one of these is broken or dirty it can cause all the symptoms you describe. All the best. Phil

It sounds like you have a vacuum leak or intake gaskets leaking. Try this. Start the engine and let it reach the idle it want to go to. Get you a can of Brake Clean and spray it around the intake manifold (it on the top center of the engine, you may have to removed a plastic cover) If the engine idle changes up or down then the intake gaskets are leaking hence your vacuum leak. I hope this will help you.

SOURCE: Replacing a throttle position sensor

  A sensor like TPS is very easy to change. It is located on the Throttle body. (the part that is at the opposite end of the air intake tube from the air box/ filter) The throttle body looks sort of like a small carburetor, if you look on the side of it you wil see a black sensor.. this is the  TPS. It is usually held on by two or three screws and it will have an electrical plug as well.

no need to replace the throttle body , and i think that you make a test before to buy any piece . disconnect the negative battery terminal few minutes, then connnect and start engine again, drive few minutes by observing the engine, if light comes again, replace only map sensor ,good luckl

1992 K1500, code 22, clicking noise from throttle body, will not accelerate properly, changed TPS with no change

OBD Code 22 - Throttle Position Sensor Error (Signal Low)
The Throttle Position sensor signals the Engine Control Module as to the current position of the engine throttle valve. The current throttle valve opening is based on the driver's input from the gas pedal. The ECM uses the information from this sensor to help calculate fuel delivery and spark timing.

* Extended cranking, possible no-start condition
* Lack of power
* Erratic transmission operation

Common Problems:
* A failed Throttle Position Sensor (TPS) would be the most common causes for code 22
* Testing the TPS circuit would involve checking voltage and ground from the ECM-5v is the normal reading between the ECM reference circuit and the ECM ground circuit at the TPS connector. Checking the TPS signal circuit to the ECM would involve monitoring the TPS signal on a scan tool while jumping the 5v reference and the signal circuits. The TPS reading should go from high when the circuit is "jumpered" to low when the jumper is removed.

Keep us updated.

When my 2003 Pontiac Sunfire starts the RPM's go way up and then finally goes down? What could be the problem?

My 1996 Pontiac Sunfire GT occasionaly bucks and jumps after running for about 5 to 10 min. I say this will happen about 20% of my driving time! Otherwise it runs great. I have already changed air and fule...

Could be tps or just a dirty throttle body or intake. They do get black inside of those. If your negative battery cable is grounded well to an unpainted surface, that could cause some intermittent jolts.
A camshaft position sensor if you have one on this car, could do that to. You should have your engine codes scanned to see if it comes up with anything. If no bad sensors are found, then clean throttle body/intake and check your plug wires.

Finding the TPS

Look for the throttle cabe and follow the cable you will see the throttle postion switch at the throttle plate in the air intake for the engine.

2002 Honda Civic Lx - TPS Sensor

The sensor does control trans.It takes a reading to where the throttle is and tells the trans what gear to be in and when to shift,down shift.So if your getting that reading and the car does not seem to be shifting right suspect that sensor..Hope this helps you and have a great day>>>

Throttle position sensor

Sounds like you have a vacuum leak somewhere on the engine. If the tps was bad, it would set a code and the check engine light would be on. Also, check your air tube that goes to your throttle body - make sure the hoses are connected tight and the tps is on the throttle body down on the front of your engine where the hose runs down to it. It's not really that hard to get the throttle body off. That would be the best way to change the tps - to take the whole throttle body off and put new gaskets on and tps on it. Hope this helps you out. PHil
