Is there a way to verify if an existing Throttle Position Sensor (TPS) is defective? Also, is there a way to check the MAP sensor as well?

Just like anyone else, I don't want to spend money on new parts when the existing ones might be just fine. I'm not getting any error codes, just trying to get rid of an occasional sputter when accelerating from a dead stop.

Here's what I've done so far: new plugs & wires, cleaned cap & rotor, removed & cleaned entire Throttle Body, fuel pressure steady at 49psi, installed new Idle Air Control (IAC) valve, verified proper vacuum w/ no leaks detected, verified no leak in the plenum, PCV good, & Oxy Sensors were just replaced. I've disconnected the battery for 20 minutes several times to reset the PCM.

Any advice, help would be appreciated. Thanks! .....Jeff...

Did you unplug it while it was running to see if anything happened? As weird as it sounds mine got stuck or something and it was idling at 2000 rpms at a dead stop. I undid my battery and it reset itself and has been fine now.

 

Auto zone had a tps with a 2 year warranty for under $50. I know when they detailed my truck they got something wet under the hood and it ran really crappy for awhile but eventually got back to normal.
