BMW 12147518628 Camshaft Position Sensor Compatible

The intake Camshaft Position Sensor on the M54 engine is located at the left side of the cylinder head close to its front. First, ensure that the ignition is turned off as a safety precaution. Remove upper engine covers and also air-filter housing with ducts. At the left side of the cylinder head, disconnect Engine Vent Hose from Cylinder Head Cover and VANOS solenoid electrical connector. Unscrew VANOS solenoid and in case of need, disconnect oil supply line from VANOS adjustment unit. Take away Camshaft Position Sensor mounting bolt followed by taking out the sensor from cylinder head. We shall reach under the Intake Manifold to remove Camshaft Position Sensor Harness Bracket Assembly so we can unplug its harness before we can take it out completely. Before removal, attach a stiff wire to the connector that will enable you to route harness during reinstallation easily. While installing new sensor use new sealing O-rings only; make sure that sensor harness is routed same way as before. Verify and clear any fault codes stored in ECM memory. Check ECU for error codes responsible for setting off MIL light. Replacing exhaust Camshaft Position Sensor on M54 engine is similar but it locates on right side of cylinder head closest to front. Besides for N52 engines, intake one mounts at left front face of cylinder head while exhaust one mounts at right front face of cylinder head. Similarly, if not identical steps are followed when replacing these sensors as for M54 engine whereby ignition should be ensured that it is off first together with removing upper engine covers, air filter housing plus ducting, detaching Camshaft Position Sensor electrical connector, removing mounting bolt and installing new one using new sealed O-rings. Verify and clear any fault codes stored in ECM memory. Walk around car ensuring every door is shut tightly or not.

Ensure the ignition is switched OFF. Remove the top engine cover (intake manifold cover). For the right Camshaft Position Sensor, take out the air filter housing and mass air flow sensor. Remove the Camshaft Position Sensor from the front of the timing chain cover on either side. Detach the Camshaft Position Sensor connector from the cable duct. Installation is the reverse of removal, keeping in mind to use a new O-ring when installing the sensor and to apply anti-friction paste during assembly. Ensure the wiring is rerouted as it was originally. Finally, check for fault codes and clear and reset the ECM memory.

The crankshaft sensor detects crankshaft position and rotation speed.

Remove the camshaft sensor mounting bolt and take out the sensor from the cylinder head.

If the CMP sensor fails, there will be no ignition spark and the fuel injectors will not be activated.

The camshaft sensor is also known as the cylinder identification sensor.
