Test Procedure

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, 2011 Ford Fusion, 2010 Mercury Milan, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
  1. JF1 CHECK FOR THE PRESENCE OF PCM DIAGNOSTIC TROUBLE CODES (DTCS) P0351, P0352, P0353, AND P0354 TOGETHER 
    NOTE: DTCs P0351, P0352, P0353 and P0354 together indicate that all 4 ignition coils lost IGN START/RUN voltage while the PCM sustained VPWR.

    Possible causes:

  7. JF7 DETERMINE WHICH COIL IS NOT FIRING PROPERLY 
    NOTE: Electronic ignition engine timing is entirely controlled by the PCM. Electronic ignition timing is not adjustable. Do not attempt to check base timing. You will receive false readings.
    NOTE: Pull on the suspect coil connector to determine if it is correctly seated before proceeding with the current diagnostic path. If the suspect coil connector is not seated correctly, reconnect the suspect connector until an audible click can be heard.
    • Determine which coil is not firing properly using the information from Pinpoint Test JB or a DTC and the table at the beginning of this pinpoint test.
    • Record the suspect cylinder, coil, and PCM pin number from the table.
