DTC P2102 Throttle Actuator Control Motor Circuit Low; DTC P2103 Throttle Actuator Control Motor Circuit High: Description

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

The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the throttle body. The throttle position sensor provides feedback to the ECM. This feedback allows the ECM to control the throttle motor and monitor the throttle opening angle as the ECM responds to driver inputs.

HINT:

This Electrical Throttle Control System (ETCS) does not use a throttle cable.

DTC DETECTION CONDITION

DTC No.	DTC Detection Condition	Trouble Area
P2102	Conditions (a) and (b) continue for 2.0 seconds: Throttle control motor output duty is 80% or more Throttle control motor current is less than 0.5 A	Open in throttle control motor circuit Throttle control motor ECM
P2103	Following conditions are met. Hybrid IC diagnosis signal: Fail Hybrid IC current limiter port: Fail When electric throttle actuator is ON (i.e. actuator power ON or actuator power supply voltage is 8 V or more)	Short in throttle control motor circuit Throttle control motor Throttle valve Throttle body assembly ECM
