1999 V70 XCAWD - P0014 code advice

Hello Everyone,

My 1999 Volvo V70 XC (180k miles) has a P0014 code “Cam Position Activator B, Bank 1, Timing Over Advance" and I am looking for some advice on what to fix. I have owned the car for about 5 years / 50k miles and the code just appeared recently. I haven't done anything with the timing or replaced anything that relates to timing so I am reluctant to think the issue is the timing being off. After some research, I have found that there are two parts that can cause this code to appear:

-Cam Shaft Position Sensor
-CVVT Solenoid

I have just replaced the cam shaft position sensor over the weekend, cleared the code, but the code reappeared after a few days of driving. The symptoms my car is having is just poor acceleration. What is strange is that when I replaced the sensor and drove it for a day or so, the acceleration issue was completely gone. It ran great! As soon as the code appeared, the poor acceleration issue came back.

Do you guys think the likely fix is replacing the CVVT solenoid, or do you think something else is causing this? Please let me know if you have any questions. Thanks in advance for any assistance you are willing to provide.

-Ryan

How long has it been since the timing belt has been replaced? You can easily remove the front timing belt cover and check your timing. At-least then your would know its timed correctly

When I purchased the vehicle, there was a service record of the timing belt being replaced around 100k.

The CVVT solenoid is known to fail. Before changing I would remove solenoid and inspect the screen on the gasket for blockage. If you get a serviceable original used solenoid P/N 1275579 it is a direct plug and play. If you get a new solenoid P/N 36002695 you will need to do some light wiring modification. The CVVT gasket P/N is 30731212.

Thanks for the reply and suggestion. I did forget to mention that a little while ago when the code first appeared, I did remove the CVVT solenoid and inspected it and it seemed okay. At that time, I just replaced the gasket with a new one, but the issue persisted. I think I will look into replacing this unless anyone else has any other suggestions?

When the ECU sets the code for CVVT it limits the turbo boost. I'm guessing that you feel that loss in performance as you describe
