Misfire Detection Monitor
MISFIRE DETECTION MONITOR
This pinpoint test is intended to diagnose the misfire detection monitor.
NOTE: Mechanical noise caused by the front end accessory drive components, mechanically driven cooling fans, or rough roads at high RPM with light load conditions may produce a nonsymmetrical loss of cylinder acceleration, which may result in a misfire.
Clearing the powertrain control module (PCM) diagnostic trouble codes (DTCs) erases any PCM recorded freeze frame data. Make sure to record any PCM freeze frame information before proceeding. See Electronic Engine Control (EEC) System.
