My 07 Volvo S80 check engine code is bringing up P001D and the Autozone reader says:

Cam A circuit Open Check Camshaft Position Sensor (CMP)

Will someone please tell me which one is Cam A from this picture: http://i1090.photobucket.com/albums/...110_210931.jpg

 

97 views, can anyone please help me? I should be receiving my new cam shaft later this week. Thanks.

 

Not trying to come off as rude, but aren't all s80 motors DOHC. Buying a new cam and leaving an old cam in will cause problems for an older motor. Why wouldn't you buy a complete set/kit? Cam A if I had to guess would be the intake cam, so the one in front closest to you when looking at the motor

 

Thanks, jrigss! You're not being rude at all. I was just looking for a response... any response and yours definitely helps. It also confuses me as well because I have not heard of that. Can Tech or anyone else confirm that? I'm just talking about the sensor.

 

I'd go to a volvo dealer maybe they would be able to tell you for certain which camshaft is A and B.

 

How did you diagnose this problem as requiring a new camshaft? It's very unlikely that that's the problem.

 

The code and the lack of acceleration is how I diagnosed it. I'm going to clean the MAS today though because I did read something about that. If you have any other suggestions, please send them my way. I'm open to trying anything. Otherwise, I'm going to thave to take it to the dealership this week to see if they have something else that will properly diagnose it further than the Autozone code reader.

 

Poor accel unfortunatley leaves a wide variety of potential problems, but I agree.. Go to volvo and use their diagnosis machines that have software built around the s80 ecu. The downside is it won't be free since your 07 is probably out of warranty

 

Yes, I just called and it's $117 just for the diagnosis. Ouch!

 

Really? I just had my 2000 in last month and the diagnosis was covered under Volvo Service for Life or some such title. The charge appeared in the itemized bill, but was then deducted at the bottom.

 

The code is probably P0010, not P001D. This code is set when there's a problem with the variable valve timing on your intake(?) camshaft. The problem is likely to be some kind of defect with the VVT circuit wiring or connectors or the VVT solenoid. I have a vague idea that the VVT solenoid can get dirty and can sometimes be fixed just by cleaning. But I don't own an S80 and am not familiar with your engine so that's pretty much as far as I can take you.

 

Thanks guys! Willvo, you were correct. I asked them about it and they passed me to someone else who said they would do a complimentary diagnostic. Migbro, I think you were right too. Turned out to be the connector to the cam shaft sensor was faulty and they replaced it. Thanks again for everyone's help!
