Same as Ford Escape.
P0351 - Ignition Coil A - Primary/Secondary Circuit

Cylinder #1, Pin 26 at the PCM, computer.

I would replace the coil on the plug (COP) for that cylinder and see if its' ok. If not, then it is possible that the bad coil took out the driver in the PCM. The test at Pin 26 to see if the light blinks, must be done with the correct tester or it will damage the PCM.

Hope it's the coil.

report results.

4 cylinder or 6 cylinder engine?

P0354 - Ignition Coil D Primary/Secondary Circuit Malfunction.

Description of DTC:
The ignition signal from the Powertrain Control Module (PCM) or Electronic Control Module(ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

Symptoms:
- Lack/Loss of Power
- The engine may be harder to start
- Engine hesitation
- Check Engine Light On
- No spark

Possible Causes:
- Open or short in the ignition coil circuit
- Ignition coil circuit shorted to ground
- Ignition coil connector
- Damaged ignition coil
- Damaged PCM or ECM

Possible Solutions:
- If damage, repair ignition coil circuit
- Replace ignition coil
- Replace PCM or ECM


P0355 - Ignition Coil E Primary/Secondary Circuit Malfunction.

P0356 - Ignition Coil F Primary/Secondary Circuit Malfunction.

P1391 - Not a valid obd code.
B1391 - Oil Level Switch Circuit Failure
C1391 - Not a valid obd code.
U1391 - Not a valid obd code.
Its possible you may have misread this code. If it is B1391 that would be the only code with 1391 for your vehicle.

P0351 - Ignition Coil A Primary / Secondary Circuit Malfunction. The ignition signal from the Powertrain Control Module or Electronic Control Module is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

Possible Causes:
- Open or short in the ignition coil circuit
- Ignition coil circuit shorted to ground
- Ignition coil connector
- Damaged ignition coil
- Damaged PCM

P0352 - Ignition Coil B Primary / Secondary Circuit Malfunction.
Same repair info as P0351.

P0353 - Ignition Coil C Primary / Secondary Circuit Malfunction.
Same repair info as P0351



Solutions:
- If damage, repair ignition coil circuit
- Replaced ignition coil
- Replaced PCM or ECM

Does the vehicle have coil on plug ignition or coilpack ? And it's not primary or secondary coil malfunctioning It's primary or secondary circuit . I'm assuming it has a coil pack because you say plug wires.
P0350 - Ignition Coil (Undetermined) Primary/Secondary Circuit Malfunction Each ignition primary circuit is continuously monitored. The test fails when the PCM does not receive a valid IDM pulse signal from the ignition module (integrated in the PCM).

• Open or short in the Ignition START/RUN circuit.
• Open coil driver circuit.
• Coil driver circuit shorted to ground.
• Damaged coil.
• Damaged PCM.
• Coil driver circuit shorted to VPWR.

P0351 - Ignition Coil A Primary/Secondary Circuit Malfunction See the description for DTC P0350. See the possible causes for DTC P0350.
Pull the spark plugs out an look at them , check the gap ,if too wide replace them . If the spark plug gap gets too worn ,the spark won't jump the gap. It will find the least resistance path to ground ,and it will do it inside the coil . Going from the secondary circuit back to the primary coil an to ground through the PCM - engine computer . The PCM has transistors inside that open an close the primary side to ground ,this builds up a magnetic field around the secondary inducing high voltage spark . Well this can short out the transistor inside the PCM . Most of the time that's what these type codes mean . The PCM would need to be replaced an programmed . This can also damage the catalytic converter. Your best bet , take your vehicle to a qualified repair shop.

These codes are for a malfunctioning ignition coil/s.
P0351= ignition coil A primary/secondary circuit malfunction.
P0354= ignition coil D primary/secondary circuit malfunction.
visually check the coil packs for burn marks, damage, loose wire connectors, and the wire harness to each of the coils for damage. How long has this been happening? Has any work been done recently? Did the engine compartment recently get wet?

Integrated ignition coil on plug

Ignition coil F is cylinder number 6 need to check or replace
Spark plug or coil,

Very rare you have to check PCM pin E39 to see if you have a short in the wire.
