Trouble diagnosis name: Throttle control motor circuit short

Component Description

The throttle control motor is operated by the ECM and it opens and closes the throttle valve.

The current opening angle of the throttle valve is detected by the throttle position sensor and it provides feedback to the ECM to control the throttle control motor to make the throttle valve opening angle properly in response to driving condition.

DTC detecting condition:

• ECM detects short both circuits between ECM and throttle control motor.

Possible cause:

• Harness or connectors (Throttle control motor circuit is shorted.)
• Electric throttle control actuator (Throttle control motor)
