Replace intake camshaft position sensor on 2001 BMW 325ci

Use you VIN number to find out the engine and wiring specs. M54 E46 is just a body code. Engines has variants too.

Check this video. BMW E90 Inlet Intake Camshaft Sensor Remove Replace E91 E92 E93 2006 2011

I think the engine is misfiring because of cam position sensor.These can be the possible causes :
- Faulty Intake Camshaft Position sensor
- Faulty Camshaft Position Solenoid Valve
- Engine mechanical condition - Valve timing off
- Intake Camshaft Position sensor harness is open or shorted
- Intake Camshaft Position sensor circuit poor electrical connection

i doubt its a sudden occurrence. Get the throttle body off and clean it with carb cleaner until its spotless. Check all breather pipes on manifold and intake side and make sure they are clean. Other possible cause is bad throttle position sensor.....

I'm confused. You are asking about camshaft position for a BMW 325ci in a question posted under 2000 Mitzubishi Endevor and didn't mention WHAT ABOUT camshaft position....???

Hi

The codes are P0019 Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor B) &
P0044 HO2S Heater Control Circuit High (Bank 1 Sensor 3)

The camshaft sensor is located on the engine above the alternator. You will need to unscrew the vanos soliniod to replace the sensor

If the car is having trouble maintaining idle (the tach dips and car dies) the common causes are the idle control valve and camshaft position sensors. The cam sensors failing will be indicated by a check engine light.

The ICV can removed and cleaned with good results (I think there is a write up on bimmerfest) or purchased new for about $100.

While you are in there check the intake boot that is Y shaped for cracks, it's prone to fail and will mess up your idle too.

read up on the major forums and you'll get more info

If the fuel filter has been replaced, then maybe these are other reasons:

1. intake camshaft sensor (known to go bad on BMW E46s). ~$100 part.

2. fuel injectors (though I doubt they go bad that easily). ~$100/ piece. Your car has 6.

3. Ignition coils. ~$90 a piece. Your car has 6.

4. mass air flow sensor. Again, another expensive part. ~$300.
