2005 Ford E350 code issues Sign In

I just replaced all 8 cylinders in my Ford E350 box truck - 5.4L I now get the following codes:

PO113 IAT Sensor 1 Circuit High Input
PO113 Pending
PO102 MAF or VAF A circuit low input
PO 2106 - not even listed in my codes book

Can anyone shed light on what these may indicate and what I might of done when changing cylinders?

What do you mean you changed the cylinders?

Inspect the MAF sensor connector. Make sure the wiring or the terminals aren't damaged.

Thanks, Sorry, I changed the plugs and coils

It is an Ford e350 v8, 5.4L gas engine

Will check the sensor..

Re: 2005 Ford E350 code issues Sign In

My last post consisted of asking for help with the following codes:

PO 113
PO 113 Pend
PO 102 Pend
P 2106 Pend.

Since then I have done a physical check of the wiring and all seems fine. The check engine light, then, went off..Today it just came back on with the following codes:

PO 354
PO 356
PO 351 Pd
PO 353 Pd
PO 354 Pd
PO 356 Pd
PO 357 Pd
PO 358 Pd

I understand it is a wiring issue, what can I do myself before taking it in.. Has anyone else had this type of issue? Could it be as simple as replacing the wiring connectors...(they do get minipulated a bit when replacing the coils, boot and plugs which I did, hence the beginning of all these code issues..)

Thanks

Did all these codes show up before you did your tune up and replacement of the coils? Did you replace all the coils?

All those codes are primary coil circuit faults for every coil on that engine. Usually when you have a coil primary circuit problem the coil that the code sets for isn't firing, so you have a rough running engine with misfires.

Did you unplug any coils while the engine was running or while the key was on? Is the engine running bad? Clear the codes and see which ones come back.

How about low supply voltage from the EEC relay?

Hello, and thanks for the response.

The codes were not there before changing all the coils. I changed 6 of the 8 (the other 2 I did within the last year). I did not unplug and of them with engine on...the engine seems to run fine however. I will clear codes and retest..

If the codes clear, "what do I chaulk this up to?"

Thanks,

I have coil code issues in my truck again, most are pending. The truck runs fine, very smooth if fact. The wiring harness looks good as well as the connections. I had code issues before but they cleared, they are back though..any thoughts?

Thanks..

That looks like some kind of problem with the supply line.

Re: 2005 Ford E350 code issues Sign In

Is this the wiring harness? Or something beyond it?

Re: 2005 Ford E350 code issues Sign In

Could be any number of things like wiring, connectors, relays, fuses etc, and that's assuming my wild guess is even correct. It needs to be diagnosed properly with a lab scope.

Re: 2005 Ford E350 code issues Sign In

What is funny is that you said it seems to run fine. Normally if you have a coil circuit code, there will be a misfire occurring at the same time. Faults in the primary circuit and the coil doesn't fire.

It could be an intermittent problem too, so that is a possibility.

HT is right that the primary coil circuits should be connected to a lab scope and checked out. Maybe the replacement coils have some sort of design difference, making the PCM think there is a primary circuit fault.

If the harness and coils check good, you could have a problem with the PCM itself. The ignition control module is built into the PCM. When the ignition control module doesn't detect a coil firing it doesn't send the IDM signal to the PCM, so the PCM thinks the coil circuit is open or shorted.
