Misfire Monitor and Readiness Code

WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. 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.
