2007 F150 5.4L with Gryphon

[Caforddude]

So I got a call a few ago telling me my truck was ready and the problem has been resolved, or resolved itself.

They said all they did was an oil change and that corrected the condition. They ran it for a bit and did not get any codes. They said when they drained the old oil it came out brown and gritty...

I have not picked up the truck yet so I do not know what the paperwork says but I will let you know if it says any different when I get it.

I have taken a few things from this incident:
1) Rancho Ford in Temecula has horrible customer service. Stick with established dealership relationships like I have always preached in the past and these types of incidents can probably be avoided. Shame on me for not following my own advice.
2) As much as I have defended Wal-Mart's oil changes as being fine, because of this bad experience I will not take my truck back to them for service.
3) the 2009 Chrysler Sebring, while cute, has less guts then a 3 legged donkey.

OH YEAH ALL FIXED...I DIDN'T EVEN FREAKIN MAKE IT HOME BEFORE IT DID THE EXACT SAME THING AGAIN!!!!!!!!!!!!!!!!!!!!!

FREAKIN IDIOTS AT THAT DEALERSHIP ALL THE WAY AROUND. I'M NOT A MECHANIC AND I CAN SEE AND HEAR IT AIN'T WORKING RIGHT

These are their notes word for word.


"Eng runs really rough and the ck eng light is not on

Check engine light on eec test codes p0012 p0022 p0340 pinpoint test. log data. found vct errors of -53 deg. recommend change oil and filter then retest. road test after service. retest pass."

Both of their test drives combined were 6 miles. My drive home from the dealership is 6 miles. problem happened about 4 miles into drive for me.

Another user was kind enough to give me the trouble codes meanings. His post.

P0012 = "A" Camshaft Position - Timing Over-Retarded (Bank 1)
P0022 = "A" Camshaft Position - Timing Over-Retarded (Bank 2)
P0340 = Camshaft Position Sensor Circuit Malfunction

If the cam timing exceeds a maximum calibrated limit or is stuck in a retarded position, will set codes P0012 or P0022 or both. dealer recorded your VCT at -53 degrees.

Possible causes are:
Incorrect camshaft timing
VCT solenoid valve stuck open or continuous oil flow to piston chamber
Camshaft advance mechanism binding, or faulty VCT unit

P0012 & P0022 codes are caused by a mechanical fault of the VCT unit or related components.

Symptoms may include:
rough idle
stall or hard start.

Perform specific component tests for the VCT unit outlined by FMC.

P0340 indicates that a problem was detected in the camshaft position sensor circuit. This means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM.

Symptoms may include:
Hard starting or no start
Rough running / misfiring
Loss of engine power

A code P0340 could mean one or more of the following has happened:
- wire or connector in the circuit could be grounded/shorted/broken
- camshaft position sensor may have failed
- PCM may have failed
- open circuit exists
- crankshaft position sensor failed

Generic diagnostics for P0340:
Visually inspect all the wiring and connectors in the circuit
Check for continuity in the circuit wiring
Check the operation (voltage) of the camshaft position sensor
Replace the camshaft position sensor as required
Check the crankshaft position circuit
Replace circuit wiring and/or connectors as required
Diagnose/replace the PCM as required
