How to know if your variable timing solenoid is bad?
Symptoms of a Bad Variable Valve Timing Solenoid and How to Replace 1 Check Engine Light On. 2 Dirty Engine Oil. 3 Roughness in Idling Engine. 4 Decline in Fuel Efficiency.
When to replace a variable valve solenoid ( VVT )?
Now that you know what all symptoms indicate variable valve timing solenoid failure, you must also know that it is imperative to replace a faulty VVT solenoid. Once you have diagnosed a problem in the variable valve timing solenoid, it is best that you either get it replace or do it yourself.
How does the variable valve timing system work?
The function of the VVT is to control the open and shut timing of the valves so as to maximize fuel economy. Any malfunction here can cause wastage of fuel or dip in performance. If you notice decreased fuel economy, chances are that the variable valve timing sensor or some other part of the VVT system is failing.
What’s the best way to replace a solenoid?
Step 11: Lube the solenoid. Apply the lithium grease to the seals on the solenoid spool. The spool is the part you are inserting into the port. Step 12: Insert the solenoid. Take the new solenoid and insert it into the mounting surface hole. There is slight resistance when installed but that indicates the seals are properly snug.

How does the PCM control the VVT solenoids?
The PCM controls the VVT solenoids based on input from various sensors. Typically, there’s one VVT solenoid for each actuator. Some vehicles only have an actuator on the exhaust camshaft or the intake camshaft, while others have actuators on both.
