PINPOINT TEST HD: Misfire Detection Monitor: Introduction
WARNING: This page does not describe the selected car, but rather 25 other vehicles, including the 2012 Lincoln Navigator L, 2012 Lincoln Navigator, 2012 Lincoln MKZ, 2012 Lincoln MKX, and 2012 Lincoln MKT. However, it is still accessible from the selected car via links, so may be relevant.
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 non-symmetrical loss of cylinder acceleration, which may result in a misfire.
This pinpoint test is intended to diagnose the misfire detection monitor.
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. Refer to FREEZE FRAME DATA .
