DTC U0107: Lost Communication With Throttle Actuator Control ModuleGeneral Description
The powertrain control module (PCM) uses the serial signal line for two-way communication with the throttle actuator control module.
The PCM transmits the accelerator pedal position signal, etc., to the throttle actuator module, and the throttle actuator control module transmits the actual throttle valve position signal, a malfunction signal, etc., to the PCM.
When no serial signals from the throttle actuator control module are received or the serial signals are abnormal for more than a set time, the PCM detects a malfunction and a DTC is stored.
