U0107

What it means

The Throttle Actuator Control Module has stopped transmitting on the vehicle data bus, so other control units no longer receive its messages. Electronic throttle control can drop to limp mode with sharply reduced power. Typical causes are loss of power or ground at the module, an open or shorted CAN/LIN bus wire, a connector fault, or an internal module failure.

Is it safe to drive?

This code can put the vehicle into limp or reduced-power mode. Avoid extended driving and have the vehicle diagnosed promptly.

Most likely causes

  high

  One of the most commonly reported causes for this code — check this first.

• CAN wiring to throttle module broken

  medium

  A plausible cause — test and verify before replacing parts.

• Gateway module routing CAN messages incorrectly

  low

  Less common, but worth ruling out after the more likely causes.
