U0107 Lost Communication with Throttle Actuator Control Module
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.
