P0123 help???

[Trowa3909]

Hey guys, I have a 97ex, I did the 99-00 si B16a2 swap in it and it has run well for over a year now. But tonight I had a CEL come up, and it is a P0123 code which is 'Throttle Position (TP) Sensor Circuit High Input' Any ideas of a problem or how to fix it??? Thanks

change your throttle position sensor

I have heard of TPS sensors getting high voltage if they are logged with water lol.. did you wash your car recently? Just try resetting the code for now and see if it comes back...

Is the engine running rough or surging at all? Also check the wires and make sure there's no short, etc, and clean the TB.


If you do all that and you still have the code, I agree with Jersey8, replace the TPS.
