I recently bought a 2001 v70 turbo 2.4 liter.
Initially when buying it , about 4 codes came up that were related to the ignition coils - I replaced all of the ignitor coils and spark plugs - all those codes went away( yay) ... Another code that came up when I bought it was "P0014
Exhaust b camshaft position timing over advanced bank 1"

After clearing all the codes, as I mentioned,all of the ignition coil related ones stayed off - however the P0014 code still comes up and now ....
"Po234 Turbo charger super charger Overboost condition"

I'm hoping if I replace the camshaft position sensor , that 1 it will take the p0014 code of and 2 perhaps the turbo related code is coming up due to the camshaft sensor....

Also, I was surprised by how much the part is - first o'reilly's said $400 something but NAPA said $200 something.

Anyone have any experience in these codes ?

 

Your cam timing code is probably being set because the cam timing is not correct - not because the sensor is bad - So you might want to check/set the cam timing correctly and make sure the variable cam timing is working correctly.

The overboost code - you just purchased the car - sometimes people make adjustments to the wastegate trying to get more boost - to make the Volvo station wagon faster. Hey, I understand I've done the same thing beginning with a 1981 240 turbo, then hilton and other tunes on later cars - I would trust the code and proceed with the diagnostic steps outlined for each code in VIDA. (The Volvo factory service manual)

If you don't have a copy of VIDA, or are not aware of the info you can get from it - you should download and install the stolen/hacked copy of VIDA 2014d. It's easily found, Swedespeed has a copy in their OBD section. You can click on the code in VIDA and it will give you a list of things to check and the factory diagnostic process. Well worth the 0 dollars!

 

Thank you,

These are really helpful suggestions!
I'm going to download the vida.

The process of tuning the camshaft sounds a bit more advanced than just replacing it. I'll need to do some research.

Also, I looked at swedspeed and couldn't locate the obd section. But perhaps I need to sign up with them to access that Information.

Again, thanks for the help!!

??? I'm sorry I don't understand replacing versus "tuning" the camshaft.

You don't replace a camshaft (well you can but you would still have to set the camshaft timing) , and

Sure, you can replace the cam timing valve (occasionally they are bad or the oil line to them is clogged) - and waste $$$ dollars - or maybe find out what the real problem is the first time.

A stored code does not mean that a part is bad - it means the computer thinks there is a problem related to the part -

 

What I mean is :
Replacing the cam shaft timing position sensor.

My thought is ,

If the sensor is not functioning properly, then the timing wont be functioning properly...

so ,

replacing the sensor will hopefully fix the timing ?

 

It sounds like you want a quick fix and have convinced yourself that a part is bad rather than diagnose what the real problem is. It gets very expensive and frustrating to try to repair cars that way.

There is a reasonable diagnostic process for any repair - randomly replacing expensive parts because you think they are bad is not a reasonable process.

Those cam sensors are very reliable, I've replaced almost 90 of the 1991-1998 cam positions sensors because they failed - but for the 1999+ cars with a new style sensor, I've replaced 1 on a 6cyl s80 back in 2010.

The first step would be to verify the cam belt is installed correctly, and the VVT system is working properly. It could be that the cam timing is simply one tooth off - or the filter screen in the VVT gasket is clogged (due to lack of oil changes)

Modern cars are difficult to diagnose - so if a timing belt check/re-installation is above your ability, pay a qualified shop to do it for you - sometimes to set the cam timing correctly requires a special tool - to lock the cams in position. Paying someone to do it right the first time may end up costing less than replacing expensive unneeded parts.

Google your code - what comes up is stuff like this -

"Causes A P0014 DTC trouble code may be caused by one or more of the following: Incorrect camshaft timing Wiring problems (harness/wiring) in intake timing control valve control solenoid system Continuous oil flow to VCT piston chamber Failed timing valve control solenoid (stuck open)
