Camshaft sensor code 65

Hi,

That is a BMW code. It is the same as a P0340 which indicates either the cam sensor is not synchronized with the crankshaft sensor or it isn't sending a signal. See pic 1.

Have you replaced the sensor? If not, the first thing I would do is simply inspect it and the connector to it. Make sure nothing is loose, damaged or corroded. I will supply the directions for replacement so you can see location.

Let me know if this helps. Keep in mind, this could even be related to a stretched timing chain.

I hope this helps.

Take care,

Interestingly, often times they go into a predetermined sequence allowing the vehicle to run in a manner which seems normal. However, fuel economy and performance are affected.

Hi,

Do me a favor. We need to check things at the connector. The brown wire is ground to the PCM, the yellow is the signal wire to the PCM. The black wire is power from the PCM.

Check for those things at the connector. If they are good, then something is throwing off the timing between the crank and cam sensors. At 180,000 miles, the chain could be stretched.

Let me know.

Naser, the power wire is the black one; the signal is yellow. A test light may make things a bit tricky. As far as power, (should be around 5v) the light should turn on when the key is in the run position. Checking signal is different and I don't think it will work with a test light.

Make sure to check for continuity to ground as well.

Joe

That is what I would suggest. You should see a pulse signal and I don't think a light would work.
