Can a bad TPS cause problems with the A/C?

possibly... in the tune there are functions of how much throttle position is required to turn the compressor off.

if you are revving it at in park and the ac is kicking off, try unplugging the TPS and see what it does. Had a car once that did that and when we unplugged it, the ac stayed on..

The A/C is turned off at WOT, is the TPS is reading such a percentage it will turn it off or keep it from engaging.

The low pressure switch can keep it off as well.

^ what they said.............do u have a Check Engine light on??

Yes, and it's throwing two codes...one is the TPS and the other is the skip shift.

I think the next question is whats the AC doing? not turning on at all sometimes turning on or what?

BowtieGirlZ28

Yeah, sometimes it runs and sometimes it doesn't...I guess I'm going to charge it and see if it helps.

pressure test it! wallmart sells the stuff cheap that will charge it and has a gauge to see what psi its running, its in a blue bottle.

If its turning off and on at idle it could just be low, or your TPS could be throwing weird signals making it think you are going wot or something..? im not positive about that but im pretty sure that the two problems arnt going to be related..

If you go ahead and replace the TPS first you can rule it out just to be safe, TPS cost about $8 from autozone and takes like 30 seconds to install.

Yea but its not a simple plug and play, at least sometime you need a volt meter to make sure your voltage settings is correct for idle and wot, I have had to slot the holes in the TPS in order to get the proper voltage..

What he said ^^. I just had to **** with that when hogging out the holes for the tps to make it adjustable so i can get the proper voltage out of it.

a bad tps sensor will definatly cause the issue you are describing........replace the tps and go from there

good luck!!
