Can't program throttle.

09 Viper, start and idles fine but no throttle. Have e done relearn a number of times. Scanner shows DTC P2166 and 2167. Says IN PLANT TEST FAILURE. What is that? Erase codes and they come right back. Checked all wiring and cleaned throttle bodies but still same thing. Any body else had this problem. Going to check all the sensors and components before I start buying parts.

Cheap scanners can display throttle % without even needing to run the car. You can just put it on run position and pull up the throttle parameter.

I do have a good scan tool. Erased all the DTC's. Start car and the only P2166 and P2167 comes up. Suggested repairs that I have found so far is that it is a problem with the ECM, the Throttle sensors (that I just replaced ) or the gas pedal which is a $4000.00 item to replace because the potentiometer in it can only be serviced as a unit. Has anyone else had a problem like this? I would appreciate hearing from you if so.
