The code you have P0012 means: Camshaft Timing Over-Retarded. There are potentially other symptoms as well. My scanner says that it's over retarded on bank one. On the end of the sylenoid there is a worm gear that accually turnes to set the correct degree. Heaven only knows what I'd have been charged at a repair shop? It made my day, but seriously, if you can avoid an engine failure, more so if the warranty is out, you should. The door locks lock and unlock to confirm the new code is programmed.
Spray silicone on all exposed rubber elbows from time to time. For an explanation of the system electrical operation and overview of the manufacturer reasoning to install this system in the vehicles see the. Additional comments for consideration regarding the P0012 code The camshaft phaser controls the timing advance and retard function through oil pressure and oil. I baby this truck and need it running. I do run motorcraft oil filters.
One other thing: To help ensure that the engine would pass smog tests, I put 92 octane gas in it for a few days. Then it threw 9 codes. I stomp it when the light turns green and it took off like a bat out of hell. On my F150 the two valves are one part together where the air pump connects as well as the feed to the exhaust manifold.

Truck ran alot better not perfect. Talked to a few mechanics and they said try replacing the Camshaft position sensors. What causes the P0012 code? It could be the Camshaft Position Actuator on Bank 1 or Computer and even Wiring Related.
Camshaft Position Actuators change the lift of the camshaft up to 25 degrees. The engine will run with a pure vacuum on both valves but may stall at idle. I would not do this without a harness … adapter kit like a stingpro F-5511 or a merta 5511. Not only did the P0411 go away but also the P0171 and the pesky come-and-go P0174.

You might also need the manufacturer and data systems that provide specifications and details relative to your specific model. Note: Your drive problems will change depending on the camshaft timing positions when the camshaft stopped advancing. The misfires are from incorrect timing and affected fuel mix. It runs fine until I go to slow down at a light or stop sign. So, if you have low oil pressure or dirty oil, it can keep them from doing their job properly, and trigger P0012.
Then it threw 9 codes. Mine was loose so I merely tightened it. It may be advisable to flush the oil system with a flush designed for this. What are the symptoms of the P0012 code?
