2015 Exhaust Fliud System Fault

mchan68 · September 27, 2018

Got an interesting one here. A 2015 F-250 with the Engine Idled Fault displayed in the cluster apparently for no reason. No DTCs on demand or in continuous memory. Where do I go with this? Anyone else run into this before?

Any permanent DTC's? I would still try performing the drive cycle to see if it will clear.

Today I had a 2016 F750 in with a check engine light and it passed KOEO and had no CDTC's BUT I saw DTC P245C in the permanent DTC list. Turns out the customer was messing around with the truck and cleared the code - Warmups=0 Distance cleared=0.0. WTF!!!

BTW that P245C was caused by a missing vacuum cap on the line coming off the vacuum pump where a hose would connect on a 4X4 equipped pick up. Looked like a critter took it as there were what looked like tooth marks on the nipple. Muddy paw prints all over under the hood. 2nd time I have seen this. Must be tasty rubber.

Nope. This one didn't even have any permanent DTCs nor the Check Engine light on.

Did TSB 14-0192 and truck is now fixed.

Just had one like this. 2012 F-350 pickup. So the tsb technically does not apply. Exhaust fluid system fault-engine idled, on message cluster. No codes. Did tsb 14-0192 cleared out message fine.

Have done multiple repairs for the Exhaust System Fluid Faults. Check out my YouTube channel Powerstroke Tech Talk w/ARod. A lot of good content!

I have one in my bay right now that wont clear. I've tried the drive cycle 5 times, with no luck. It had a blown fuse 36 for the NOX Modules. Replaced the fuse and have been unable to clear the fault since. I did notice that the PC/ED Drive Cycle Procedure is different than the Drive Cycle Procedure in 14-0192. There are some minor differences. I will try the TSB version tomorrow. Hopefully it helps. A buddy at a dealer in Silverthorne Colorado states they have been replacing the PCM for this concern? Has anybody heard of that? I typically haven't had an issue performing the drive cycle.

I remember the very early ones very early in their lives had a pcm that wouldn’t reset once it went to an idle only fault. But I seem to think that they fixed that issue.
