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 P0014 when the accumulated deviation is too high. The target camshaft position is predetermined value depending on engine speed and throttle angle in the ECM.
