P2107

Throttle Actuator A Control Module Processor

Throttle actuator control (drive-by-wire) Generic OBD-II High

What it means

P2107 means the throttle actuator control module (the drive-by-wire "brain" that moves the throttle plate) has detected an internal processor fault. Because the module can no longer trust its own throttle control, the PCM usually commands reduced-power or limp mode as a safety measure, so the engine feels sluggish and unresponsive.

High

Can I keep driving? Drive gently and get it looked at soon — this usually forces the engine into reduced-power or limp mode, so acceleration and highway merging can be unsafe.

Common symptoms

What you'll notice

Common causes

Most likely first

  1. Internal fault in the throttle actuator control (TAC) module or PCM processor
  2. Corroded or loose connectors / damaged wiring to the throttle body
  3. Faulty throttle actuator motor or throttle body assembly
  4. PCM software fault requiring a reflash or update

How to diagnose & fix

Work through it in order

  1. Scan for companion throttle codes (P2101-P2112) and read freeze-frame data to see the conditions when it set.
  2. Inspect and clean the throttle body, then clear the code and re-test — a sticking plate can trip the processor's self-check.
  3. Check the throttle-body connector and wiring for corrosion, bent pins, and good power/ground.
  4. Check for a PCM/TAC module software update or TSB for the vehicle.
  5. If the fault is internal to the module, replace or reprogram the TAC module / PCM as specified.

FAQ

Quick answers

Is it safe to drive with P2107?+
Only briefly and gently. It typically drops the engine into reduced-power mode, so acceleration is limited — get it diagnosed before relying on the car.
Can I just clear P2107?+
You can, but if the throttle module's internal check keeps failing it will return, often putting the car back into limp mode.
