Help. 2007 F150 5.4L

[CaFordDude]

I currently have a Gryphon and am running the 87 performance tune.

Ok so earlier this week I started hearing wat sounded like a little rattling noise at certain RPM's. I assumed a loose exhaust clamp or something simple I could do when I had the weekend off. Truck has also been hard to start. I assumed maybe needed a new battery even though mine is only 2 years old


Today I was running low on gas and pumped in some 91 octane, only about 5 gallons. Drove home and idle at lights seemed a little rough. Picked up my daughter and headed home. Get home and stop just outside the garage to let my daughter out. Start to pull into the garage and engine starts running REALLY rough. Bouncing between 3-500 RPM's, low based on what I have seen.

Pull the code and I get:
P0012 Intake Camshaft
Position timing
over retarded (bank 1)

Code looked exactly as posted above.

Tune issue? octane issue? Other issue? Any help would be greatly appreciated. I am heading to the snow this weekend and do not want to get stuck up there...

Thanks.

possible causes: camshaft timing incorrectly set---continuous oil flow to the vct piston chamber----erratic camshaft position due to low oil pressure----oil flow restriction in the oil passages or vct valve body---vct solenoid valve stuck open---open or short in the vct circuit---open vpwr circuit---camshaft advance mechanism binding (vct unit)---damaged vct phaser----damaged camshaft position sensor---open or short in the cmp sensor circuits---radio frequency interference (RFI)

So it really sounds like it could be mechanical OR computer?

'fraid so! More examination is necessary.

Just had one in the shop yesterday, same code and noise on drivers side, Left side of the engine was wasted, cylinder bores scored extremly low compression, attempted to sell them a $10,000 engine job.

more than likely, the cam acuator has failed. unless your maintainence is below average on this truck (which i doubt) there should be no issues. in my opinion, the tuner should not have caused the failure.

I was told there might be a TSB covering this issue? Anyone know if that is true or not?

I don't see anything in the 07 5.4 tsbs. I do know the cam phasers aren't very trustworthy.

I dunno if you guys will see this before I leave but is a p1000 code going to be an issue?

When this whole mess first started it started with my truck being hard to start. I thought maybe my battery was going. The truck is only about 18 months old BUT does have 33000 miles so I thought maybe the battery was toast. I took it to the local store to have it tested and they said it was fine.

I have looked up and seen that the p1000 code is for the obd tests not being comleted and that could be caused after the battery has been disconnected and then reconnected. Just trying to make sure I have my ducks in a row.

Thanks guys.

P1000 is just that, OBD2 tests aren't complete. Just disregard unless you're going to do extensive diagnostics.

And they are pulling the valve covers tomorrow to check the cams and what not. Not exactly sure what they are checking for, abuse, broke, stuck...

All the service writer could say was I have NEVER seen both sides go bad before unless it was related to an oil change with a crappy filter...


I'll keep ya posted.

You're making a lot of guys jealous getting a brand new motor for free.
