SFI SYSTEM DETAILS CAMSHAFT TIMING OIL CONTROL VALVE

  1. CONSTRUCTION

    1. This camshaft timing oil control valve assembly controls the spool valve using duty-cycle control from the ECM. This allows hydraulic pressure to be applied to the advanced or retarded side of the VVT-i controller. When the engine is stopped, the camshaft timing oil control valve assembly is in the most retarded position.
