174 Camshaft Adjustment, Bank 1 - Signal Implausible: Function

In order to increase torque and improve cylinder charging, the engine is equipped with two VarioCam actuators that are incorporated in the camshaft chain tensioners.

The actuators change the position of the inlet camshafts with respect to the outlet camshafts.

The position of the inlet camshafts is checked by the camshaft position sensors.
