Camshaft Reference/Position Sensor, OEM - E36 323i/328i/M3, E39 528i, Z3 2.8
OEM cam position sensor and direct replacement for BMW part #12141703221
The engine computer takes the camshaft position from this sensor to assist in setting timing and even when starting the engine. A bad cam position sensor will lead to hard starting and reduced power as the engine computer reverts to 'safe mode' maps. There will also be a fault code and check engine light for camshaft reference sensor.
This sensor fits all M52 and S52 engines fitted to the 1996-1999 E36 323is/328i/M3, 1997-1998 E39 528i, 1997-1998 Z3 2.8, and 1998-2000 MZ3 S52.
A new o-ring is not included with the sensor. Please order the o-ring separately (see link below).
