2005 Mustang GT TPS question

[jbpt1970]

I have been getting failsafe mode with p2106 and p2135 codes. I considered it the TPS and attempted to change it myself after cleaning my "stock" throttle body. The care would not come out of failsafe mode. I reinstalled the old TPS and cleared the codes and it ran fine for 1 week, then failsafe again. I have a C&L street CAI with predator tune 93 octane. Will this require return to dealership? If so, should I return to stock? My car is no longer under warranty. Thanks.

Could be the sensor wires, I had someone not to long ago with this same problem and it was not the sensor, but a faulty wire. If you are going to go to the dealership, I would return the car back to stock.

Check the TPS voltage and verify that it is the proper range. You can adjust it by turning the hex screw that is on the top driver side of the throttle body. Google for the procedure and proper range of the voltage.
