Camshaft Position Sensor 2 -G163-, CHECKING: Function

Using the signal from the Camshaft Position Sensor 2 -G163-, the precise position of the camshaft relative to the crankshaft is determined very quickly when the engine is started. Used in combination with the signal from the Engine Speed Sensor -G28-, the signal from the Camshaft Position Sensor 2 -G163- detects which cylinder is at TDC. The fuel can be injected into the corresponding cylinder and ignited. In case of signal failure, the signal from the Engine Speed Sensor -G28- is used instead. Because the camshaft position and the cylinder position cannot be recognized as quickly, it may take longer to start the engine.
