DTC P174E? (6.4)

drunk on diesel · Jun 2, 2015

6.4 custom tuning on the X4 is relatively new. There are going to be teething issues.

anybody want to buy a $700 XRT PRO street?

This truck is relatively new to me and I'm just starting to play with it, so I'm not sure how to tell this yet.

Yes, X4 7015.

I will contact Matt directly if my internet searches prove useless, but I wanted to put in my effort first.

No not yet

Look at your build date on you door jamb sticker.

Let me know what Matt says about the code. Thanks

I just spoke to GH. They said that the code comes from them rolling the strategy back in their tune. Stock your TCM and ABS module both have the most current flash, but when they wrote the tune they chose the strategy with the least oil dilution problems. With the tune loaded the PCM is picking up on the ABS module and TCM module not matching and it throws the code.

So it won't cause any problems?

if you have a check engine light on, that's a problem in my book

I wonder if this code will cause shifting or that high idle problem I have LOL.

have you always had the high idle problem or only with this tune?

Not according to them. It's a soft code with no CEL and that's the extent of it.

I agree it's a nuisance, but I don't think it's anything more than that. If they're correct in their assessment I don't look at it any different then the EGR codes I used to get on my 6.0. They tune kept the CEL away and prevented any driving issues, but the code was still there when I pulled the DTC.

Give them a call and ask. My truck has been having a weird 2-3 shift that I thought might be related to this code, but the shifting issue went away yesterday. I suppose it was still just learning my driving style.

if they're no CEL, I consider it a non-issue

Only when we started to get into the "single turbo" tunes love the tune its near perfect but the high idle and this code lol.

6.4 P174E code

Sorry to resurrect an older thread but theres not too much info out there on this. did any of you guys solve this code?
I just finished my 2008 f350 project. cab off, studs, single setup, new built trans, new fuel pumps etc. I getting 3 codes
P2701
P0756
P174E

The truck does not shift into 2nd or 5th. Due to the first 2 codes. Im wondering if the 174E code is causing this. I just installed GH tunes.
