Camshaft sensor

The camshaft sensor is mounted at the top rear of the cylinder head cover. The DDE control unit provides the sensor with an earthing point (M_NWG). Via the activated terminal 87, the camshaft sensor is supplied with on-board supply voltage. The camshaft sensor is designed as a Hall sensor.

There are three different segments at the back of the camshaft and these move past the camshaft sensor. The DDE control unit evaluates the resulting voltage signal (three different square-wave signals per camshaft revolution).
