Highlander car fault code p2 1 1 1

Throttle actuator control system-stuck in open position

Throttle actuator control system-stuck in open position

Category: Fuel, Air or Emission Control

Detailed meaning: In the Electronic Throttle Control (ETC) system, the function of the accelerator pedal position (APP) sensor is to transmit the position of the accelerator pedal to the throttle control module in the form of an electrical signal, which serves as a reference for the throttle actuator to control the throttle opening. The throttle actuator is a stepping motor, which is responsible for controlling the throttle opening according to the instruction of the throttle control module. Causes of failure include electronic control module (PCM or ECM) failure. It is recommended to clear the fault code. If the same fault code appears again, the electronic control module needs to be replaced.
