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 sensor, which is mounted on the throttle with motor body assembly. The throttle position sensor provides feedback to the

ECM. This feedback allows the ECM to appropriately control the throttle actuator and monitor the throttle opening angle as the ECM responds to

driver inputs.

HINT

This electronic throttle control system does not use a throttle cable.

MONITOR DESCRIPTION

The ECM determines that there is a malfunction in the electronic throttle control system when the throttle valve remains at the fixed angle despite a

high drive current from the ECM. The ECM illuminates the MIL and stores a DTC.

If the malfunction is not repaired successfully, a DTC is stored when the accelerator pedal is fully depressed and released quickly (to fully open and

close the throttle valve) after the engine is next started.
