The TPS must be set with a voltage meter. What are the code numbers? Air flow meter will not let it idle too. Get a used one to save you money. Be sure you do not have the ecm number 1228253 in it also,they will make the car shut off while driving. I have one of the cars with 295,000 miles on it.

Camshaft position sensor problems


Lets start at the beginning. I doubt the trouble code said "replace the cam sensor". It probably said there was no signal from the sensor or it was out of range.
If you replaced the cam sensor, and it was the right sensor for the code, it could be a wiring problem or something mechanical with the camshaft itself.
BTW, there are two sensors, one on each cyl head.

Car chugging when stopped. I have replaced tps but doesn't fix. Stops chugging when tps is removed.


The TPS is used by the vehicles ECM for power enrichment,and idle stability when you remoce the sensor connector the ECM uses a substitute value so you can drive the vehicle. So the TPS is not the problem here You are basically suffering from a vehicle lean condition or false air. Removing the TPS connection only enrichen the car.Trouble shoot the MAF (mass air flow ) this is the one that houses the air filter check the boot going to the intake manifold make sure its not cracked or leaking air giving false air.2_24_2012_5_22_13_am.gif

Code 22 on 95 gmc sierra what does that mean also t will start up but wants to die we replaced idle air control valve and also the throttle position sensor did not fix it i check vaccum lines all good it...


Trouble Code 22 indicates that the Throttle Position Sensor (TPS) is reading abnormally low. TPS volts should be close to 0.42 V at closed throttle and rise smoothly in about 0.02 volt increments to a maximum reading of about 4.85 volts at WOT.
Typical causes for this code include:

1) Maladjusted TPS
2) Defective TPS
3) No +5 volt reference to TPS
4) TPS-return to ECM is shorted to ground or to sensor ground
5) Defective ECM

Good luck, i hope this helps.

After reading the trouble code I changed the throttle positioning sensor and now it gets too much fuel floods and will not start.


You have to zero out the postion sensor with an ohm meter. disconnect the plug for the TPS then with an ohm meter turn it to where ohm meter reads 0 ohms with throttle closed, next tighten screws then with ohm meter still connected open the throttle plate it should read 0 ohms till the plate opens and then should increase as it is put in wide open throttle postion, if it goes stratigh over to full postion then the swich is defective remove and take back to autoparts store. then restet the new switch, it is common to get a bad TPS every once and a while.

Adjustable throttle position sensor


I'm assuming you have the 3.3l v-6. When I look up the part, it seems to have slotted holes. Therefore, it is designed to be adjusted after installation. If your tps has these slotted bolt holes, adjust it to satisfy the settings in the test procedure below.
  1. Remove air cleaner. Disconnect the TPS harness from the TPS.
  2. Using suitable jumper wires, connect a digital voltmeter J-29125-A or equivalent to the correct TPS terminals A and B.
  3. With the ignition ON and the engine running, The TPS voltage should be 0.3-1.0 volts at base idle to approximately 4.5 volts at wide open throttle.
  4. If the reading on the TPS is out of specification, check the minimum idle speed before replacing the TPS.
  5. If the voltage reading is correct, remove the voltmeter and jumper wires and reconnect the TPS connector to the sensor.
  6. Reinstall the air cleaner.

Car idles


If it revs up and down you need retrain the car to idle. I know it sounds crazy but you need to ask dealer or local shop the steps to do it.

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.
