Note! Some variation in the illustrations may occur, but the essential information is always correct.
Removal
Remove the CPS solenoid. Refer to: CPS solenoid, B6324S See: Service and Repair/Removal and Replacement/CPS Solenoid
The CPS (Cam Profile Switch) solenoid has four inputs/outputs: (1.) Port T, (2.) Port A (3.) Port T and (4.) Port P
A CPS solenoid does not have a built in spring. It is therefore necessary to press the valve in slightly during fault-tracing to get the solenoid to work
satisfactorily during the test. Use a short M8 screw or similar.
The lack of spring also means that it may sound as if something is loose inside the solenoid if it is shaken. This is completely normal.
Press in the valve slightly.
Blow compressed air into the A port (2).
Air should come out through both return holes (1 and 3).
For further function checks, continue with "checks". If the duct appears to be blocked, go to "cleaning".
