The fault is a circuit malfunction. the coil will be attached to no 1 cylinder. Check all connections or replace the coil attached to no 1 cylinder.

SOURCE: Check engine light comes on. p0171 and p0351 codes found

From Lusty Kid:

I know the economy is bad, but change all of the plugs. Check your PCV Valve hose, 150 rottens them out allowing air to be sucked in, thus all kinds of codes.

Depending on mileage. Dismount the EGR valve and clean passages. If you are really good dismount the throtle position sensor body and clean out passages with Choke Cleaner., dismount where the EGR valves connects to the engine, clean out passages. Also check the hose thats behind this mounting to ensure is not clogged. If clogged clean it out. If not replace it. Is about 1.5 ft. long, connects to the PCV Valve Hose.

When is the last time you change your harness. Can't remember??? Replace it. Good Luck

Hi, it sounds to me like voltage to your coils is low. Unfortunately, I do not have a wiring diagram for your car. I suggest you use a voltmeter to check the voltage at the coils with the key on. If you can do this and report the voltage back, maybe another FixYa expert with a wiring diagram or firsthand knowledge can help you with this problem. In any case, please respond to this solution so that the question can be released back to the FixYa team at large.

SOURCE: Need diagram for ignition coils

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.

From a reputable repair website:


P0351 - OBD-II Trouble Code

Auto Systems and Repair

Ignition Coil "A" Circuit Primary/Secondary Malfunction Our emissions expert has put together the following information about the P0351 fault code. We have also included diagnostic procedures you can take to your repair shop if the mechanic is having difficulty analyzing the code.
OBD II Fault Code
  • OBD II P0351 Ignition Coil "A" Circuit Primary/Secondary Malfunction
What does this mean? The ignition coil or coils are responsible for igniting the air/fuel mixture inside the combustion chambers. Without reliable performance from the ignition coil(s) the vehicle will stumble and misfire.
Code P0351 indicates there's an electrical problem in either the primary ( the computer side ) or the secondary ( the spark plug side ) of the Ignition Coil "A" Circuit.
Symptoms
  • Check Engine Light will illuminate
  • Engine idles rough
  • Engine misfires on acceleration
  • In rare cases, the engine may not exhibit noticeable symptoms
Common Problems That Trigger the P0351 Code
  • Defective Ignition Coil(s)
  • Defective Spark Plug(s)
  • Intake Manifold Vacuum leaks
  • Carbon buildup in the Throttle Body air passages
  • Defective Idle Air Control Valve or Electronic Body
Common Misdiagnosis
  • Ignition coil(s) replaced when cause of the malfunction was a vacuum leak
  • Spark Plugs replaced when cause of the malfunction was a vacuum leak

What are some common causes to get trouble code P0351 Primary/Secondary Ignition?


i think this has a coil pack, if so it is a common failure it will give a random misfire code most cases. and also the crank sensors are known to fail .. jay

Codes p0351 miss and is goverened at 2800 rpms.


P0351 is Ignition Coil A Primary/Secondary Circuit Malfunction.
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
Possible solution - If damage, repair ignition coil circuit - Replaced ignition coil - Replaced PCM or ECM When is the code detected? The test fails when the Powertrain Control Module (PCM) or Electronic Control Module(ECM) does not receive a valid pulse signal from the ignition coil.
P0351 Description: 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.
Hope this helps :)

Miss fires and stots off when I give it gas as codes 1391 ,0351, 0352, 0353,


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

I have a 2004 Ford Taurus ses with a 3.0 liter v6(not the dohc model either). Today the check engine light came on. I took it to autozone to have the code run and they told me that it could be the primary...


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.

Engine codes P0354 P0351 engine skips low power


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?
