Variable valve timing actuator • Continuously modifies the phases of the intake camshaft and crankshaft at the forward

end of the intake camshaft using hydraulic pressure from the oil control valve (OCV).

Oil control valve (OCV) • Operated by current (duty signal) from the PCM. Switches the hydraulic oil passages

to the variable valve timing actuator.

CKP sensor • Inputs engine revolution signal to the PCM.

CMP sensor • Inputs cylinder identification signal to the PCM.

PCM • Controls the oil control valve (OCV) so that optimum valve timing is obtained according

to engine operation conditions.
