Nice but why does the filter have to come off? Didn't need to do this on mine.

Thanks for the amazing guide! My check engine light came on while I was driving home from work. I pulled into the nearest Autozone, and they read a code for a Camshaft Intake Sensor Malfunction. After that, my car would not stay on (instead of idling it would turn off) and during my 1/4-mile drive home, my car felt like it had 50 horsepower.

I changed it without removing my oil filter canister, the only difficult part was getting an allen wrench that fit.

Thanks for write up especially the pics. Took me about 45 min. only because I had trouble finding the right size wrench to take off the vanos solenoid. Ended up breaking it with a large crescent wrench but had to finish with a channel lock to have enough room to turn it. Took off the airbox. Disconnected the tube above the vanos. Took off just the top and filter of the oil canister, didn't remove the whole thing. You just need enough room to get a ratchet with 5mm hex in there. Much easier than wrestling with an allen wrench. I tried, it sucked. The clips on the solenoid and the bottom end of the sensor were really easy to take off (just push the curved section of the little metal clip and pull you don't need to pull the metal clips out). Tied a shoestring to the old sensor when I pulled it out and pulled the new one back down the same way. e46fanatics is the best website ever!

What is this mysterious tube?

Hi All,

I was working to replace the CPS on my '01 330xi, and the "tube in Step 2" started cracking. I'm going to need a replacement, but I'm not sure what to ask for.

Does anybody know what this is, or better yet, have a part number for it?

Thanks,
Ryd

Yeah just did this. This was an intermittent problem my car would stall every time I came to a stop or as soon as I decelerated. Started to get dangerous! I bought the part from autohauz for 70 bucks works like a charm.

Yes, there is more than one camshaft position sensor. This DIY is for the intake side. There is also an exhaust camshaft position sensor.

What part is "the pipe" in Step 2

Whats that pipe that we need to disconnect in step 2.
I broke mine since it's old.

I doubt it's PCV. On diagram looks different.

That pipe/hose connects to the oil seperator aka crankcase valve (CCV). There are 4 other hoses that connect to this oil seperator that often crack over time and from heat.

There are several threads that talked about oil seperator DIY.

Where is the best price I can find the Camshaft Intake Sensor for sale?

BAVAuto is about 120.

I will be performing this repair this weekend. I truly appreciate those that take the time to post these DIY guides.

What really sucks is that I replaced the VANOS seals this weekend (easy task in my opinion) and replacing this sensor would have been much easier at that time.

Live and learn....
