The throttle actuator is operated by the ECM and opens and closes the throttle valve using gears. The opening angle of the throttle valve is detected by the Throttle Position (TP) sensor, which is mounted on the HINT: This ETCS (Electronic Throttle Control System) does not use a throttle cable. DTC DETECTION CONDITION AND TROUBLE AREA MONITOR DESCRIPTION The ECM monitors the electrical current through the electronic actuator, and detects malfunctions and open Example: When the electrical current is less than 0.5 A and the throttle actuator duty ratio exceeds 80%, the ECM MONITOR STRATEGY MONITOR STRATEGY DTC Code DTC Detection Condition Trouble Area P2102 Conditions (a) and (b) continue for 2.0 seconds (1 trip a. Throttle actuator duty ratio 80% or more b. Throttle actuator current less than 0.5 A Open in throttle actuator Throttle actuator ECM P2103 Either of following conditions met (1 trip detection logic): Hybrid IC diagnosis signal failure Hybrid IC current limiter port failure Short in throttle actuator Throttle actuator Throttle valve Throttle body assembly ECM Related DTCs P2102: Throttle actuator current (low current)
