What does the intake camshaft position actuator solenoid do?
What does the intake camshaft position actuator solenoid do?
A camshaft actuator solenoid –normally installed in the front of each cylinder head — is used to precisely control the flow of oil into the camshaft actuator. This changes the rotation of the camshaft to adjust valve timing and valve overlap on the go.
How to check the intake valve control solenoid?
Installs the test intake valve control solenoid for proper diagnosis and follows the pinpoint test to check to see if the valves change during the testing Verify the failure by clearing the code and seeing if the problem is still present. Do not attempt any diagnosis without special tools like a test solenoid.
What causes bank 1 intake valve to not change?
The ECM activates the intake valve solenoid for bank 1, but the valves do not change to the high lift position. The intake valve solenoid has an open or short circuit. The wiring or connections to the intake valve solenoid is shorted or open. The ECM is defective or the connection to the ECM is loosing contact.
How to remove a bad variable valve solenoid?
You will be able to see the connector that lies at the exposed end of the variable valve timing solenoid. Once you have found it, use bungee cables to clear the area of any wires or harnesses. 4. Locating Mounting Bolts and Removing Usually there is just one bolt that you will find. In some cases there will be two.
Is the variable valve timing solenoid and the camshaft position sensor?
Hello. The variable valve timing and the camshaft position sensor are two separate sensors. The camshaft position sensor is more towards the front of the engine and is a lot easier to replace.

How does the VVT solenoid work on a car?
Most vehicles use a hydraulically-operated actuator located at the end of the camshaft to change the camshaft’s position and retard or advance valve timing. Our friend, the VVT solenoid, applies oil pressure to activate the actuator. The PCM controls the VVT solenoids based on input from various sensors.
