Fault Family System: Powertrain (P-Codes) 4 SAE Codes

Throttle Actuator Module Fault

Diagnostic & Technical Explanation

Code P2107 (Throttle Actuator A Control Module Processor) is an internal self-check failure inside the ECM/TAC processor circuitry that drives the electronic throttle, distinct from a fault in the throttle body hardware itself. A corrupted or outdated engine control module calibration, an internal driver-stage failure inside the processor, and a marginal power/ground supply to the module during the self-test are the typical causes.

These 4 diagnostic trouble codes share one detection mechanism and one repair path, which is why MechanicDB groups them into a single authored fault family rather than repeating the same explanation 4 times.
