Burrr Posted August 25, 2022 Report Share Posted August 25, 2022 (edited) I recently changed the plugs and COP on my 2013 Edge, I used aftermarket COP's not Ford. . Today we got 4 DTC's, P0304, P0351, P0352 and P0354. I pulled the coil for number 4 as this was the easiest to diagnose and found the coil shaft was cracked all of the way around abount half way down the shaft. I installed one of the original coils and cleared the codes, the car runs fine. My question is will the cracked coil cause the other codes - "Primary/secondary circuit malfuntion" in the other cylinders? The firing order indicates that the other cylinders with issues fire on either side of the bad coil.

Haz Posted August 25, 2022 Report Share Posted August 25, 2022 Congratulations on restoring your Edge to normal operation. Sorry that I cannot offer any personal insight, but perhaps you can gain understanding from the following Diagnostic Trouble Code (DTC) information and PDF download links to associated Pinpoint Tests from the all-models Ford 2013 Gasoline Powertrain Control/Emissions Diagnosis Manual... Good luck! 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. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to Pinpoint Test HD. P0351 - Ignition Coil A Primary/Secondary Circuit Description: This DTC sets when the PCM does not receive a valid ignition diagnostic monitor (IDM) pulse signal from the ignition module PCM. Possible Causes: IGN START/RUN circuit open IGN START/RUN circuit short to ground Coil driver circuit open Coil driver circuit short to voltage Coil driver circuit short to ground Damaged coil Diagnostic Aids: DTC P035x only sets for a coil primary circuit failure. A secondary ignition coil or spark plug failure does not set DTC P035x. DTC P030x does not set for a coil primary circuit malfunction. DTC P035x may set with or without DTC P030x; however DTC P035x sets first. When this DTC is set, the PCM enters failure mode effects management (FMEM) which shuts down the injector for the associated cylinder in order to protect the catalytic converter. This is normal operation; do not attempt to diagnose the injector with this DTC present. If a primary coil is damaged due to a harness short to ground the PCM will not be damaged. Do not replace the PCM without verifying the coil driver functionality. Use the 12-volt non-powered test lamp to verify START/RUN voltage at the ignition coil harness connector. Check the coil driver circuit for open, short to voltage, or short to ground. Application Key On Engine Off Key On Engine Running Continuous Memory Fiesta GO to Pinpoint Test JE. All others GO to Pinpoint Test JF. P0352 - Ignition Coil B Primary/Secondary Circuit Description: This DTC sets when the PCM does not receive a valid ignition diagnostic monitor (IDM) pulse signal from the ignition module PCM. Possible Causes: IGN START/RUN circuit open IGN START/RUN circuit short to ground Coil driver circuit open Coil driver circuit short to voltage Coil driver circuit short to ground Damaged coil Diagnostic Aids: DTC P035x only sets for a coil primary circuit failure.

WWWPerfA_ZN0W Posted August 28, 2022 Report Share Posted August 28, 2022 did you have codes before you did the work? how many miles on your vehicle? did you use motorcraft plugs or are they aftermarket as well? although relatively uncommon on this generation, the pcm may be suspect if the coils check out. but seems like these aftermarket coils may not be quality at all. you can check basic stats using the method shown here 1 Quote Link to comment Share on other sites More sharing options...
