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 cm

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.
