2001 S60 2.0t, 3 fault codes.

SuperB · Jan 1st, 2015, 16:54

Hi folks.
I recently picked up a 2001 S60 2.0t automatic. It has a few issues, but runs and drives really nicely.
It has 3 fault codes and the engine management light is on.
P2090 Exhaust camshaft reset valve; Signal too low or signal missing
P0245 turbo/supercharger waste gate regulating solenoid valve A low
P0445 evaporative emission control system purge control valve curcuit shorted

I have done a bit of searching on the forum and have found the p0245 fault is the boost solenoid just to the right of the engine. I'm going to replace this.
I have not found much information on p2090 and p0445 other than earthing problems being the possible cause to p2090.

Can anyone advise me on how or what I should be doing to rectify these 2 ?

Many thanks in advance

Take the top cambelt cover off, under there on the left hand side of the top of the engine is the camshaft reset valve/solenoid. Make sure the cabling is in good order.

Thanks John, I'll look into that tomorrow.

Had a look at the wiring today and traced it back to where it joins the loom. All looked in good order and each wire has continuity up to where it joins in the main loom.
Does anyone know what ohm reading the solenoid should display on my multimeter?

I'm getting 4.2 ohms terminal to terminal on the valve.
1.9v to one of the plug terminals with the ignition on.
The other terminal has no resistance to earth, suggesting a good earth.

Did you ever solve this? I have the same 3 fault codes.
