Pcm Code E055, TPS Out Of Adjustment: Action

At next key on, PCM will log PCM Code E055 as current. No diagnostic light or service message will appear.

1. This step checks for TPS adjustment. PCM parameter ED01 displays uncorrected TPS so it can be used to check TPS adjustment.
2. TPS adjustment is okay.
3. If TPS adjustment is okay, ISC and throttle switch operation need to be thoroughly checked. Throttle linkage needs to be checked for proper operation. Check throttle and cruise cables, ensure throttle valves are not binding, check for proper throttle return spring operation and ensure throttle shaft and blades move freely.
