2007 ford edge changed the plugs at 100000 now getting engine codes Po351 & PO354 is is this a PCM reset problem

Some of the most common repairs for a P0354 code include:

• Replacing or repairing a leaking manifold vacuum
• Replacing faulty wiring to the ignition coil(s)
• Replacing old or mismatched spark plugs
• Replacing or repairing the ignition coil(s)

What repairs can fix the P0352 code?

• Replacing the coil pack
• Replacing the spark plugs
• Repairing a vacuum leak such as a leaking intake manifold gasket or cracked vacuum line
• Replacing the Engine Control Module
• Repair or replacement of any damaged coil pack wiring

These ford coil on plug ignition systems have a habit of frying the transistor inside the PCM - engine computer that controls the firing of the coil. . If the coil driver ( transistor ) inside the computer is fried it will need to be replaced an the computer programmed ,dealer .

The check engine light comes on when your vehicle has a problem with the OBD 2 - onboard diagnostic's system . (emissions) When the light is on there are DTC'S - diagnostic trouble codes stored in the PCM - engine computer ! Changing the spark plug's may or may not do anything . There are a number of sensors that send signals to the PCM so PCM knows how much fuel to add to the engine . You need to take your vehicle to a qualified repair shop an have it check out .

Trouble Codes Check Engine Light On

Replace all the spark plugs &
all the ignition coils

Replace the oxygen sensors,
if over 100,000 miles on them

Codes for ignition coils are not always accurate

You can get many codes for many cylinders & have one or more
bad coils

I would do a cylinder leak down test, to eliminate a mechanical
valve sealing issue

Then if all valves seal-- smoke the intake for vacuum leaks

PO301,PO351 or Coil A -- are all the same-- cylinder #1

Do you know for a fact cylinders one two and four are firing ?
The codes are for circuit problems with the coils on those cylinders. The coils get power from the PCM power relay and the engine computer grounds each coil to fire the spark plug. The codes mean the coils are not firing, and since you replaced the coils there may be too much resistance in the circuits coming from the computer.

It shouldn't need programming, per se.

As long as it's the same model PCM, you should be able to plug it in and go.

Misfire P0351,P0352,P0353,P0354,P0355, P0356 Meaning secondary circuit A,B,C,D,E,F . You may need a PCM If your car has a NGC controller it may have melted the ignition coil mounted on the spark plug. For these to happen You have a defective coil driver circuit in the PCM . This is a multiple coil failure, Before we go there lets do the basic are the connector connected? How about the conection at the juction area all connected, then pcm failed. These are secondary what is the secondary the signal that allows the coil to collapse the magnetic field and gives spark.

It's probably the 4th which is all the way in the back on the left side when you are standing in front of the vehicle facing the engine. There is a water line that runs above that cylinder and drips condensation into it allowing for problems. It's best to replace the plugs AND the (coil pack--which run $60 each).

I just worked on 98 expedition 5.4l had code PO354. This code refer to an open primary coil winding, open wire, or bad PCM.
Check primary winding with ohm meter should be from 0.5 to 1.5 ohms and about 2.5 ohms with a hot engine. check wiring with a noid light, run the engine and shake the harness if light goes out repair harness you should have battery voltage with key on the computer controls the ground side.
