6.7 Code Issues, Lets Discuss

Breaking Habits · Jun 18, 2014

Alright,

I'm at my witts end.

2014 F450, Delete Pipe, Mini Maxx.

New MAF Sensor

8700 Miles

Has a code for Mass Air Flow Circuit High, and Lost Communication To Glow Plug Module.

The GPM code has been gone for months, and just came back today.

Just updated to the newest Ford Calibration, supposedly fixes the glow plug module code.. I call BS

And the MAF code is there. The H&S is completely updated.

Im scratching my head here. I need this thing straightened out.

do you have an SCT you can toss on it instead?

Breaking Habits · Jun 18, 2014

No, the 13-14 stuff glitches too much still. I wont mess with it until they get their stuff together 100%

Why not call H&S............

Setting a code with a stock intake? You didn't list an aftermarket one in your post, but I know you're pretty fond of the S&B units...

I wasn't trying to be mean I hope it didn't come off that way. They never actually sold a "Race" tuner for a 13-14 so you can't really trouble shoot with them

Why don't you pull that thick bitch in the shop while you're working magic on the phone lines?

We did today. Levi updated it. I replaced the sensor. How do you fix a lost communication and an error code for a new sensor?

The intake is stock. I love my S&B's but this is a stock one unfortunately

Check fuse #36 in the battery Junction box. If it's bad then unplug your nox module completely and install a new fuse. I am willing to put money on it that that is your problem.

I guess I don't understand the exact issue going on but fwiw Bentley did tell me that the Nox sensor is on the same circuit as the glow plug module. You short out your Nox for some reason you loose your glow plugs. Good luck.

My truck had the same exact problem. When I was trying to diagnose it we found that it had no power going to the MAF so we found out what fuse it was and replaced it and as soon as it was put in it blew. We seen that the glow plug control module and nox module shared the fuse with the MAF so I just unplugged the nox module since I didn't need it anyway and away went my problem. I don't really know why it went bad because it obviously wasn't being used but it shorted out for some reason.

Shot in the dark would be whatever module(s) in that circuit could have a fault. I tried to find a wiring diagram with no luck sorry amigo

Wrong truck. Disregard post. Thought it was your 13' under the knife.

That's deff a crazy problem between NOx and GP.

I spoke with them a few weeks ago about a '12, tech support was happy to help me. May be different for a '14 though

Yea, I completely remove the nox module when I do a delete. Hopefully jared can track it down.
