2000 V40, 89,000 miles. P0341 code. No other codes. P0341 is Camshaft Position Sensor Range/Performance. Car runs fines, no obvious performance issues. Anyone have any advice on this before I start chasing it down?

I changed the timing belt and all related components at 79,000 miles. One other possibly relevant piece of information is that the black plastic split wire loom on top of the cylinder head enclosing the wires to the VVT solenoid has disintegrated leaving the insulated wires themselves touching the valve cover. I've been meaning to get back in there and clean that up before the wire insulation chafes through. First place I'm going to look, don't know if that could throw a P0341 code.

 

No help here. Please let us know what you find.

 

Will do. Haven't got to it yet though.

 

The wires are fine, the looming comes apart all the time. There's insulation on the wires for a reason.

I'd have to convert the code to a Volvo code at work, but I'd start with making sure oil is full and clean, then making sure the camshaft reset valve is clean (you may need to replace it).

 

OK. Checked the oil today - full and very clean. Checked the naked VVT solenoid wires on top of the valve cover - no chafing - and installed spiral wire loom. Timing belt tension checked and looked good - belt twists a maximum of 45 degrees between cam sprockets. VVT pulley was dry with no oil leaks.

And as of today the P0341 code has cleared itself. So.....guess I'll wait and see if it returns.

 

Damn, I've been really busy at work and forgot to cross the generic code with a Volvo code. I'll try and remember Tuesday.

So you took the belt and CVVT hub off?

 

No I didn't. Why would you do that? Not being snarky just don't understand why I'd do that much work for an inspection. There's no oil at all in the timing belt area, VVT pulley is dry.

Will probably take the camshaft reset valve off tomorrow for an inspection and cleaning.

 

I don't know why you would do that either, which was why I asked. But after re-reading, I see I misread it the first time.

I'll check that code out on Tuesday. But I've seen plenty of CVVT hubs need replacement without showing leakage. Cleaning the valve is obviously a much easier (and cheaper) first step though.

 

Just took the valve off. Looks good with no visible carbon or debris. The piston looks a little varnished so I'm soaking the (non-electrical) part of the valve in some carb cleaner right now.

 

due you smell gas in the engine oil ??.....dip stick smell test.....might be a fuel problem. i had this problem with my v70

• also Check that the wiring isn't routed too close to any secondary ignition components (coil, spark plug wires, etc.)
• Visually inspect the wiring at the sensor for any burn marks, discoloration indicative of melting or chafing...........any wires that look suspect ..migbro i would attack .....
• .i re-covered many wires that had too much exposure in my opinion......and said with plain common sense ......." that can not end up good if i dont do something about it . ...hope it hepls ya.......yes im having electrical issues throwing codes when every thing is fine....ps we are trien to help you

Dude, I knew you didn't write that as there are no grammar or spelling errors. So thanks for the copy and paste from this Yahoo answer.

Google, outing plagiarists everywhere.

 

To be honest, I really don't have a problem with you researching the code on Google. Nor do I have a problem with the difficulties you have with the English language. What I do have a problem with is some random sentence fragments being presented as helpful advice. So look into your heart and tell me, is it me who is a pric (sic) [LOL] or is it you who is sorely lacking in self-awareness and dare I say it, integrity?

 

p.s som of the letters dont worc on my computer buddy thats the honest truth IN MY HART.. ..ans somtimes it pumps out random letter its just easier to past ....what i meant about corrosion, burnt wires and so on ....THATS THE HONEST TRUTH FROM ONE VOLVO OWNER TO ANOTHER.......BARE WITH ME IS ALL I ASk......im trien to help.....if i seen a volvo @ side of road in trouble and is was u i would stop ....and make you smile 100% truth.NO HOMO my buddy just bought a s40 for his wife with my advice (265lbs monster ....and he loves the car..so any info u give i pass along. That's what this is all about @ volvoforums

Can I ask you a friendly question .What kind of scanner due you have??

 

Just buy a new keyboard... They aren't expensive. And that doesn't account for the terrible spelling. Do and due are two different words. So are half and have.

 

Haha okay tough guy. Internet threats are cool.

Got a chance to check the code, it actually isn't related to the CVVT. Its likely either corrosion at the camshaft position sensor connector, a problem with the wiring to it or a bad camshaft position sensor. Certainly not very common at all.

 

i agree with you.......

 

Thank you. I really appreciate you taking the time to look that up.

So you have access to a database that links actual reported problems to DTCs? That's awesome.

 

No problem.

I do have access to a database like that, but it isn't very reliable. It is mostly independent shops using generic OBD-II codes.

Sometimes, the description of a generic OBD-II code does not actually mean what it says it does. So I prefer to use the Volvo codes in VIDA, which usually contains a list of possible causes and some fault tracing. The fault tracing is pretty incomplete for your code, unfortunately.

 

i agree .....you got mad info es6t..props
