Engine code P0012 : Variable cam timing over-retarded. Changing the phasing of both cams can increase or decrease the overlap. Then release the accelerator pedal. A good scan tool would probably help too. Some examples of this include while a vehicle is carrying additional weight, traveling up hills, or when acceleration is expedited through throttle control.
This is what allows just the right amount of oil supply, this allowing the engine to give great and fuel efficient performance. Please or to join the conversation. Replace the solenoid, remove the rag and reinstall the cover. Ford uses several types of systems on different applications to perform these functions, and the type of setup they use dramatically effect the advantages gained. Apr 11, 2011 Code P0012 - Variable Camshaft Timing Over Retarded - Bank 1 How does a P0012 code trigger the check engine light? It can, in fact, practically monitor all the individual parts of the car. It controls the intake camshaft actuator. You will need to remove the valve cover, the timing cover, then remove the timing belt, the camshaft sprockets, and finally the camshafts to remove the vct solenoid as it goes around the camshaft.
Make sure that you keep the cables aside by preferably trying them down with a bungee cord. This oil supply actually travels through the block, into the camshaft front bearing, through the camshaft, then finally into the phaser. The correct viscosity of oil is being used. Please or to join the conversation. This is a small electrical solenoid located on the top of the engine. I recommend you read through that article first before this one.
This replacement job should be straightforward, and the only issue is if you have been driving the car for a while with the solenoid not working as it should. Thank you for using FixYa, have a nice day. Another thing is if the truck is at or above 2000 rpm, no problems. In most cases though, the mechanic can change out the solenoid quickly and without any complications. Locating Mounting Bolts and Removing Usually there is just one bolt that you will find.
