P2107 - THROTTLE ACTUATOR CONTROL (TAC) MODULE PROCESSOR

Description:  The electronic throttle control (ETC) area of the powertrain control module (PCM) failed the self-test. The concern could be the result of an incorrect throttle position (TP) command, or TAC motor wires shorted together.
Possible Causes: 
  • TAC motor harness circuit short to ground
  • TAC motor harness circuit short to voltage
  • Damaged electronic throttle body (ETB)
  • Damaged PCM
Diagnostic Aids:  This DTC may be accompanied by other DTCs. Diagnose other DTCs first. A TAC motor circuit PID reading may indicate a concern, if available.
