1.2L REVOTRON ENGINE 175 III. SOLENOID VALVE (OIL CONTROL VALVE) COMPONENT DETAILS The variable camshaft timing oil control solenoid (also called the Camshaft Position (CMP) actuator) is attached to camshaft and is hydraulically operated in order to change the angle of the camshaft relative to Crankshaft Position. The variable camshaft timing oil control solenoid is controlled by the control module. The control module sends a pulse width modulated 12 volt signal to a variable camshaft timing oil control solenoid. The solenoid controls the amount of engine oil flow. The control module increases the pulse width to accomplish the desired camshaft operation. Coil resistance -7.4 ± 0.5 Ω at 20˚C. Insulation resistance -50 M Ω Min (With 500V Mega Ohm meter). Leakage shall be 1.0 cm3 / min. COMPONENT LOCATION TESTING 1. Ensure the vehicle has the proper oil viscosity. 2. Observe the engine oil level. The engine oil level should be within the operating range. 3. Allow the engine to reach operating temperature. 4. Increase the engine speed to 1,500 RPM. 5. Command solenoid to 25 percent. The angle desired parameter should match the solenoid actual parameter. NOTE Once dropped, should not be use. CONNECTOR DETAIL PINOUT DETAILS PIN DESCRIPTION 1 - Ve Side 2 + Ve Side
