VVT Solenoid Replacement

Material Needed
Engine oil (any grade)
Multi-bit driver set
Ratchet / sockets
Wrenches - box/open end

Step 1: Locate the VVT switch. If so equipped, remove any intake covers for easy access.

Once removed, locate the correct VVT switch you are replacing: suction side or exhaust side.
Once located, remove the electrical connector, paying attention to how much force you use. The underframing of plastic components becomes brittle due to the heating and cooling cycles of the engine.

Step 2: Remove the VVT switch. The VVT switch is typically held in place with a mounting bolt.
Remove it and set it aside. Carefully pull the switch out of its mount, making sure the o-ring or seal is removed along with it.

Step 3: Clean the VVT switch mounting area with a rag. 

Clean the mounting area to prevent dirt or debris from entering the mounting/bore surface.

Making sure the new o-ring/gasket is in place on the new VVT switch, dab a little engine oil on the o-ring so it slides into place without damage. Secure it in place with the mounting bolt and reconnect the electrical connector.

Step 4: Check for leaks. Before replacing the removed engine covers to access the VVT switch, start the vehicle and check for leaks.
Also, check that the check engine light is not on. Once verified, turn off the engine and reconnect any covers.

Step 5: Clear the codes. 

If you don't have a code reader, most vehicles usually clear the error codes automatically after 5-10 ignition cycles: starting the vehicle, driving, shutting down.
