P2107: Throttle Actuator A Control Module Processor — what it means, the affected system and what to check before replacing parts.

Meaning, symptoms, causes and checks

Throttle Actuator A Control Module Processor. Basic catalogue definition; diagnostic details have not yet been reviewed.

Affected system: Powertrain

Symptoms

  • A throttle-control warning or restricted engine response may occur.
  • The engine may not respond normally to accelerator demand.

Possible causes

  • The throttle-control module may detect a processing or control fault.
  • Damaged actuator wiring, shorts or an electronic throttle-body fault can require exclusion before suspecting the module itself.

What to check

  • Read companion throttle-control codes and inspect the actuator harness for shorts or open contacts.
  • Check power, grounds and motor circuit using the vehicle's repair specifications.
  • Evaluate control-module faults only after peripheral circuits and the throttle body have been tested.

Also written as: P2107-00, P210700 (some scan tools add the fault-type byte, e.g. -00).
