P0011

DTC P0011 "A" Camshaft Position-Timing Over-Advanced or System Performance (Bank 1)

DESCRIPTION

The CVVT (Continuously Variable Valve Timing) system is installed to the chain sprocket of the exhaust camshaft There is no variation in valve timing of the exhaust cam because the exhaust camshaft is driven by the timing belt. The timing of the intake cam is varied by the relative operation the CVVT vane to the housing. This system helps the engine decrease exhaust gases and increase engine power and fuel economy by changing the valve open/close timing of the intake camshaft.

DTC DETECTING CONDITION

1. DTC Description
The deviation of the camshaft position from the target point is evaluated during stable driving condition. The ECM accumulates this deviation for a certain period and sets DTC P0011 when the accumulated deviation is too high. If this error code is set again in the next driving cycle, the ECM illuminates the MIL.
The target camshaft position is predetermined value depending on engine speed and throttle angle in the ECM
