CEL has been on on our 99 V70XC for the past several months, however the performance, etc. has been unaffected. We just had the timing belt, tensioners, water pump, etc. changed out and the light has come back on. The tech that worked on it has narrowed the problem down to the Cam Adjust Solenoid.

I have gotten a new solenoid and gasket, and am curious if I should reset the CEL, or just install the new part and let the computer on the car re-set it.

Any info will be very helpful--THANKS!!
