What does p0012 mean on a Volkswagen Passat?
It affects vehicles with variable valve timing (VVT). The list of VVT vehicles is growing, and the Volkswagen Passat can have VVT, and is known to develop this code. P0012 is generic, which means that it has the same definition for the Passat as it does on any other vehicle.
What kind of timing actuator does a p0012 have?
With P0012, the camshaft actuator is leaving the timing retarded. Camshaft Position Actuators change the lift of the camshaft up to 25 degrees. They are hydraulic, which means that they use the vehicle’s engine oil to control lift.
Why does my Ford Escape have a p0012?
With P0012, the camshaft actuator is leaving the timing retarded. Camshaft Position Actuators change the lift of the camshaft up to 25 degrees. They are hydraulic, which means that they use the vehicle’s engine oil to control lift. So, if you have low oil pressure or dirty oil, it can keep them from doing their job properly, and trigger P0012.
What does p0012 stand for in VVT?
P0012 is generic, which means that it has the same definition for the Passat as it does on any other vehicle. VVT changes the frequency and distribution of gases entering and exiting the combustion chamber. It allows the engine to act as though it has different camshaft profiles at different RPM’s.
What causes the variable camshaft timing code p0012?
This over-retarded timing condition could be during the advancing or retarding phase of the camshaft timing. What causes the P0012 code? The variable camshaft timing (VCT) oil control valve (OCV) stuck in the open position.
What does the p0012 code on an ECM mean?
The camshaft (s) is (are) adjusted by the ECM through the use of an oil control valve (s) (OCV) also called variable valve timing control solenoid valves. The P0012 code is set when the ECM detects the camshaft timing for the intake camshaft on bank 1 is more retarded than what it has been set to be. What Are The Symptoms Of Code P0012?
What are the symptoms of the p0012 OBD-II code?
The variable camshaft timing (VCT) oil control valve (OCV) stuck in the open position. The camshaft phaser is damaged and stuck in the retarded position. Oil flow problems to the VCT piston and phaser. What are the symptoms of the P0012 code? The ECM will turn on the Check Engine Light if the timing cannot be commanded to move.
What do you need to know about error code p0012?
For error code P0012, one or more of the below repairs may be needed to solve the underlying issue. For each possible repair, the estimated cost of repair includes the cost of the relevant parts and the cost of labor required to make the repair.
