Codes P0012 and P0014

[Sky Render]

Yesterday and today, the car felt... weird. Like it was down on power or something. Today on my lunch break, I had to punch it to merge into traffic. I looked down at the tach and saw the CEL illuminated.

I pulled the codes with my Aeroforce gauge: P0012 and P0014.

Any ideas what that could be caused by? It looks like it's a problem with VCT. The engine is stock other than a cat-back exhaust, AEM intake, and Ford Racing ProCal tune.

Have you tried clearing the codes or flashing back to stock?

No, I left the codes on there for diagnosis purposes. I searched all over the Interwebs and couldn't find much on that P0014 code... What I don't understand is how both VCT solenoids on one bank could fail at the same time. Since the '14 code also lists "System Performance" as a descriptor, I'm hoping it's just one bad VCT solenoid.

I hate to do this, but I dropped it off at the dealer. Fortunately, the powertrain is still under warranty. I'm glad I paid the dealer $90 to flash the ProCal and keep my warranty.

Freaking dealer had me leave work early yesterday to drop the car off ASAP then didn't even look at it until 1400 today. Bastards.

They said they cleared the code, reset the PCM, and that everything is working fine now. They're going to hook up their diagnostic tool tomorrow morning and go for a drive to get a datalog. But it's allegedly running fine now.

^ This is why so many of us don't bother with the warranty. Simply not worth the extra time and aggravation jumping through all their hoops, plus the outrageous charges on anything they can slip in that isn't covered by the warranty. Oh, they will eventually get it right but it might take 3 trips to the dealership first because they simply cleared the codes rather than determining the cause.

I hope my negativity is unwarranted and that they treat you well.

Sounds about right for a stealership

There are precisely two dealerships that I trust with my car: Oursman Lincoln/Volvo/Audi in Frederick, MD (whose manager I went to high school with) and Keystone Ford in Chambersburg, PA (whose service manager is a family friend). I've always had great experiences with both of them.

Unfortunately, they were both totally booked this week, and I wanted to get this looked at and fixed before I leave for VIR tomorrow. So I had to take it to the Ford dealership I bought it from.

If they can't find the problem and it seems to be running OK, I guess I'll just take my ProCal scanner with me in case I need to clear codes again? And maybe make an appointment with Keystone to get some competent people looking at it?

EDIT: Just got a call from the stealership. Service Advisor person told me he took it for a drive up and down the Interstate and had no issues, no CELs, and nothing on the data log. He did say that oil contamination can cause issues with the VCT solenoids (which is true) and that running a different oil viscosity such as the 5W-30 I normally run can also cause issues (which is partially true). So I told him to do a full synthetic oil change with 5W-20 while the car is there, and I'll pick it up this afternoon.

The damn codes both came back on the way home. Shit.

Any ideas?

^Per skwerl, two more trips and the dealership will get it right....

Sorry about the bad luck with the dealership not getting it corrected before your trip.

I've been texting back and forth with @kevinatfms all evening. He first told me to check the VCT solenoid connectors. I did, and they look fine. I even checked the terminals.

Unfortunately, that leaves three things: VCT Solenoids, cam phasers, or timing chain.

None of those is going to be fixed tomorrow. I previously had the timing belt TSB done, so I wonder if that is related somehow. Then again, I had that done like 2 years ago.

Got a call. Parts ordered for VCT solenoid and the wiring pigtail.

best of luck. your mustang is in our thoughts and prayers

 

[kevinatfms]

Told you it was either the wiring or solenoids!

Glad to hear they are gonna fix it.

So replacing the VCT solenoid didn't fix the problem. And the dealer currently has no idea what could be causing the issue. Still getting codes P0012 and P0014 and loss of low-end power.

They called to ask if I had a "tune" on the car. I told them, "Yes, I paid you to install it 2 years ago to keep my warranty intact. I've had no issues with it." Said something about diagnostic procedures might change if the car has the FRPP ProCal tune on it.

Would it be unreasonable of me to ask them to just give me a new long block at this point? Or maybe replace the entire damn head and timing chain? They've confirmed it's still under warranty.

 

[kevinatfms]

Ford won't allow that. They will send a regional engineer who will verify what the problem is. Best bet is the can sprocket/phaser assembly.
The tech should be able to command a certain timing advance and hold it through IDS and then watch the output from the cam sensor. If he has done this correctly it would show the phaser being stuck at a certain timing degree.

Round two: new cam phasers ordered. <__<

Sorry to hear about the recent troubles Vince... I hope it works out.

 

[32V Stang]

hopefully that fixes it or next they'll need to pull the cam caps and check for scoring. it could be an oil pressure issue

 

[Sky Render]

True, VCT issues can be caused by oil pressure. I have an oil pressure gauge, however, and I get 22+ PSI at hot idle.

You might need a new harness too.
