I've been having my "engine service soon" light come on in my 2004 350z and after a few days it goes off, but when it comes on the car feels like it is going to stall out. The code that it keeps giving is for a TPS (tire pressure sensor) but my car does not have any tire pressure sensors? and i don't see how a tire pressure sensor would cause my car to want to stall out... Has anybody else had this issue and if so any suggestions on how to fix this problem? Thanks for your help guys.

 

Are you sure it's not Throttle Position Sensor?

 

TPS=Throttle Position Sensor
Your TPS is probably bad.

 

I had that code once..I just did the idle relearn procedure...then I cleared the code...never came back..

 

Thanks guys for the help. How do i do the idle relearn procedure?
