something to do with the throttle actuator control
|
The electronic throttle control system (ETCS) controls the throttle valve opening. The system is composed of the throttle
actuator, the throttle valve, throttle position (TP) sensors A and B, the throttle actuator control module, the ETCS control
relay, the accelerator pedal position (APP) sensor, and the engine control module (ECM).
The APP sensor is operated via the throttle cable to determine the accelerator opening value when the driver presses the
accelerator pedal. The accelerator pedal opening value is converted to a signal in the APP sensor and transmitted to the
ECM to compute the target position. The target position signal is then transmitted to the throttle actuator control module.
The throttle actuator control module determines the throttle valve target position according to the signal received and operates
the throttle actuator to move the throttle valve to the target position. The actual throttle valve position is determined by
TP sensor A installed in the throttle body.
The throttle actuator control module compares the throttle valve target opening angle and the actual throttle valve opening
angle from TP sensor A, and when the difference exceeds the specification, the throttle actuator control module transmits the
malfunction data to the ECM. When the ECM receives the malfunction data from the throttle actuator control module, the
ECM detects the malfunction of the throttle actuator system and a DTC is stored.
