Conditions For Setting The DTC

WARNING: This page is about a different car, the 2003 GMC Savana and 2003 Chevrolet Chevy Express. However, it is still accessible from the selected car via links, so may be relevant.

The Powertrain Control Module (PCM) detects a deceleration in the crankshaft speed that is characteristic of either an emission type misfire or a catalyst-damaging type misfire.
