Circuit Description

WARNING: This page is about a different variant/trim than selected.

The idle speed is controlled by the engine control module (ECM). The ECM will command the throttle valve motor to open or close the throttle valve in order to maintain the desired idle speed. If an RPM out of range condition exists, this DTC will set.
