P2135 & P0122 Piwis code

Recommended Posts

I've been having these codes lately. They are all related to the pedal and after changing the pedal sensor I really thought the codes with go away but unfortunately not. I'm on a mafless Proto tune so Maf can't be it. The pedal has a very bad delay after revving almost 2-3 sec off. If I delete code they reappear as soon as I rev.

Any clue where to go after he pedal sensor gentlemen?

Check the connections and/or replace the pedal sensor.

Related to P2135 and P0122,

I have a 02, 996 GT2 and I'm experiencing similar issues. 


Any update on how this was fixed or if you found the solution?


I have already replace the Pedal Sensor with a brand new unit, still having the issue. Now will check the TB, which ground point should i check??
