Can't program throttle.

[prodiver]

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.
