Stuck Throttle

The Stuck Throttle module detects if the electronic throttle motor is mechanically stuck (not responding to control). This is done by comparing the measured throttle position and the target throttle position. If the difference between the two values exceed Stuck Throttle Position Error Threshold for longer than Stuck Throttle Error Time, stuck throttle security activates.

When stuck throttle security activates, the electronic throttle motor is inhibited and engine kill is requested. This also triggers a DTC.

The engine kill is achieved by shutting off both ignition and injection one cylinder at a time.

NOTE: The stuck throttle system is only applicable to electronic throttle applications.
