2013 Ford Explorer Police Interceptor, AWDSECTION DTC P0301-P0309: Cylinder X Misfire Detected
DTC P030X: CYLINDER X MISFIRE DETECTED

Description: 
NOTE: x represents cylinder numbers 1 through 9.
The misfire detection monitor is designed to monitor engine misfire and identify the specific cylinder in which the misfire has occurred. Misfire is defined as lack of combustion in a cylinder due to absence of spark, incorrect fuel metering, low compression, or any other cause.
Possible Causes: 
  • Ignition system
  • Fuel injectors
  • Running out of fuel
  • EVAP purge valve
  • Fuel pressure
  • Evaporative emission system
  • Exhaust gas recirculation (EGR) system
  • Base engine
  • Misfire monitor neutral profile correction has not been relearned since the last mechanical repair
Diagnostic Aids:  The malfunction indicator lamp (MIL) blinks once per second when a misfire severe enough to cause catalyst damage is detected. If the MIL is on steady state due to a misfire, this indicates the threshold for emissions was exceeded and caused the vehicle to fail an inspection and maintenance tailpipe test.
