Camshaft Position Sensor: Description and Operation
The function of the camshaft position (CMP) sensor is to detect the camshaft flanks. The signal from the sensor is used by the engine control module
Each camshaft has four flanks per camshaft revolution. A pulse wheel on the camshaft consisting of four teeth (the teeth are positioned by each flank) is
The flanks are not symmetric on the camshaft. This allows the control module to determine which flank has been detected and therefore which operating
When the operating cycle of the camshaft is established, the control module is able to determine which cylinder should be ignited. In the event of misfire
Data about the position of the camshaft is used during camshaft control (CVVT). See Function.
The sensor, which is a magnetic resistor with a permanent magnet, is grounded in the control module and supplied with 5 V from the control module.
The camshaft position (CMP) sensor is positioned at the rear of the engine by the controllable camshaft (CVVT).
The engine control module (ECM) can diagnose the camshaft position (CMP) sensor.
