Throttle Actuator Control System – Forced Idle
P2104 Throttle actuator control system – forced idle
Description
If a problem is detected which could result in faster engine speed than commanded by the pedal, the actuator
is switched out, allowing the throttle valve to default to a 6% mechanically sprung setting. This provides a fast
idle speed which may be used to effect a 'limp home' mechanism.
