How does the CMP actuator control the camshaft?
The CMP actuator assembly (15) varies the camshaft position in response to directional changes in oil pressure. The CMP actuator solenoid valve controls the oil pressure that is applied to advance or retard a camshaft. Modifying camshaft timing under changing engine demand provides better balance between the following performance concerns:
How to replace the variable valve timing actuator?
When newly replacing the variable valve timing actuator, place alignment marks on the new part in the same position as the old actuator. If the alignment marks on the variable valve timing actuator are not available, refer to the “timing chain ASSEMBLY” in the engine and perform the sprocket position alignment again. . .. . Thank you.
Where can I get a timing chain replacement?
UMR Engines motor mechanics at 7 Moss Street Slacks specialise in engine repairs, so you know you can trust UMR Engines highly trained Engine Technicians for all your timing & installation requirements. UMR Engines is a recommended RACQ approved repairer. [/notdevice]
When to replace timing chain on Holden VE Commodore?
Timing chains are very common on these engines to fail even at relatively low mileage compared to other timing chain engines which can last well over 200,000 km. The average kilometres that we replace timing chains on these engines are around the 100,000 km mark.
What is the function of a camshaft actuator?
Camshaft A camshaft is a shaft attached to the cam. Timing between the rotation of the crankshaft and camshaft is integral to the proper function of a vehicle engine. The camshaft actuator mounts to the end of the camshaft and either slows or speeds up the opening and closing of the poppet valves via commands sent by the Engine Control Unit.

What is the timing between the crankshaft and the camshaft?
Timing between the rotation of the crankshaft and camshaft is integral to the proper function of a vehicle engine. The crankshaft refers to an engine part used to convert reciprocating linear piston motion into rotational motion.
How does the CMP actuator work on an engine?
The CMP actuator assembly has an outer housing that is driven by an engine timing chain. Inside the assembly is a rotor with fixed vanes that is attached to the camshaft. Oil pressure that is applied to the fixed vanes will rotate a specific camshaft in relationship to the crankshaft.
