P0015 = Camshaft reset valve, incorrect signal. It is not a faulty CPS trouble code.

Explanation of Camshaft Reset Valve.
Each time that the engine is switched off the camshaft pulley sets itself in the locked position. The control module checks that the camshaft pulley leaves the locked position when the engine is started again. Diagnostic trouble code DTC P0015 (ECM-61, Volvo code) is stored if the control module detects that the camshaft pulley is in the locked position.

Possible Source
1. Low oil pressure in the engine...
2. Blocked oil ducts for the camshaft reset valve...
3. Defective camshaft reset valve...
