Hi, Just replaced the VCT solenoids today, It is perfect when revving high and all that , But as soon as i start the car again it comes on with the codesP0011 - Camshaft Position 'A' Timing Over-Advanced or System Performance Bank 1
P0021 - Camshaft Position 'A' Timing Over-Advanced or System Performance Bank 2
It's rather unusual to have overadvanced cam position codes on both banks but it can happen. The cams are normally in the advanced position when parked so it seems that they aren't retarding when they should. This suggests that there may be inadequate oil flow to the phasers due to stuck VCT solenoids.
Try disconnecting the wiring connectors to both solenoids and run the engine. If there's no change you've found the problem.
Yes, it drives great but the code keeps coming back after I clear it with my ODB2 scanner, No issues at all revs good and doesnt stall easyDo you mean the car drives normal but still registers codes? If so, then you have to clear the codes witch a scanner, software, or disconnecting the battery.
I am at 93k original miles on the 2005 mustang, Is it hard to change the phasers?Well, it may seem to run fine but you still have over advanced timing or the codes wouldn't be coming back. Very good chance that it's the cam phasers. How many miles on this car? If they are the originals then it makes sense. Ford redesigned them after they were found to be subpar. Being a 2005 they would have been the first bad design before the revision. If you buy the replacement Ford phasers now they will be the more reliable version.
Like already mentioned it could be an oil pressure issue too. Low pressure to the VCT solenoids will cause these codes. If your 3V engine hasn't had the timing components changed and it's over 100k miles then you are due. Due to extreme wear my engine broke apart the plastic guides and littered my oil pan and pump with plastic bits while also skipping a couple teeth on the timing chain. Beware of this and do not let it go. I did and it cost me big. If you have about 150k or more then you are in the danger zone. The timing kit is about $800 for the complete kit of Ford made parts it's but over $1000 in labor to pay a shop to do it. It's 8 or 9 hours of labor as I recall.
