Toyota 15330-0T010 Valve Assy, Camshaft Timing Oil Control

The Variable Valve Timing-intelligent (VVT-i) it is used in all the models and helps to adjust the valve timing depending on the driving situation by changing the intake camshaft timing through the intake engine oil pressure that changes the controller on every intake camshaft. This system has two CMP sensors, PCM, two VVT-i oil control valves, and two intake camshaft sprocket or actuator. The controller also has the timing rotor of VVT-i sensor, the housing of which includes the impeller-type vane, lock pin and the timing chain sprocket of the intake camshaft, and the vane is fixed on the end of the camshaft. The camshaft timing oil control valve is managed by PCM which specifically shifts the oil flow to advance or rear areas of the controller; one for each camshaft. To remove the oil control valve, make sure that the ignition key is off, then unclasp the engine cover, unplug the electrical connection of the valve and shift the engine harness. Subsequently, to disassemble the valve when the mounting bolt is taken off, and assembling is done in the backward manner. For testing the OCV should be disconnected and its resistance between the terminals should come to between 6.9 to 7.9 ohms at the atmospheric temperature. Also, applying battery voltage to the OCV while observing the connector terminals should show positive voltage on the right and negative on the left; this should not exceed a few seconds. If the OCV does not meet the specifications or does not perform correctly it should be changed.
