Circuit/System Description

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

The engine control module (ECM) uses information from the crankshaft position sensor to determine when a misfire is occurring. By monitoring variations in the crankshaft rotation speed for each cylinder, the ECM can detect individual cylinder misfire events.
