Misfire Monitor and Readiness Code

WARNING: This page is about a different car, the 2006 Acura MDX, 2005 Acura MDX, 2004 Acura MDX, and 2003 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

This readiness code is always set to available because misfiring is continuously monitored.
Monitoring pauses, and the misfire counter resets, if the vehicle is driven over a rough road.
Monitoring also pauses, and the misfire counter holds at its current value, if the throttle position changes more than a predetermined value, or if driving conditions fall outside the range of any related enable criteria.
