Duct connected to chamber (a)
Duct connected to chamber (b)
Oil feed duct
Oil return duct
When the VCT control unit is being advanced, the chamber (a) fills with engine oil. The
rotor (3) starts to turn counter-clockwise as a result of the EOP prevailing in the chamber
(a). This completes the advance adjustment. The engine oil returning from the chamber (b)
flows via the oil return duct (D) to the VCT oil control solenoid and from there back into the
oil pan.
VCT oil control solenoid
The VCT oil control solenoids are located in the front area in the centre on the valve cover.
The purpose of the VCT oil control solenoids is to supply engine oil to the VCT control units
in accordance with the actuation by the PCM. This causes the camshaft/valve timing to be
either advanced or retarded.
