Low oil levels can also cause problems with the VVT solenoid and other timing system components. Typically the VVT system does not activate until the engine is at higher RPM or is introduced to load bearing situations like driving uphill. However, if the VVT solenoid is malfunctioning, it is possible that it will introduce additional engine oil to the VVT gears.
This can cause the engine to idle rough , specifically the engine RPM to fluctuate as the system is activated. If not checked quickly, it can cause additional engine components to wear prematurely.
If your engine idle is rough , make sure to have a certified mechanic inspect this as soon as possible. The purpose of variable valve timing is to ensure that the valves open and close at the right time to maximize engine performance and reduce fuel consumption. When the VVT solenoid is malfunctioning, the entire system can be compromised, which may result in intake and exhaust valves opening and closing at the wrong time.
This typically causes the fuel economy to drastically reduce. If you recognize any of the above warning signs of a bad or failing variable valve timing solenoid, contact a local ASE certified mechanic from YourMechanic.
They can inspect your vehicle, replace the variable valve timing solenoid if needed, and keep your car or truck running strong. This article originally appeared on YourMechanic.

Changing the oil and filter to the proper oil viscosity for the engine specifications. Repairing or replacing the wiring to the camshaft oil control valve for bank 1 intake camshaft.
The powertrain control module PCM transmits a signal to the solenoids to move a valve spool that regulates the flow of oil to the phaser cavity. You should replace your oil control valve as soon as you notice it has problems. In internal combustion engines, variable valve timing VVT is the process of altering the timing of a valve lift event, and is often used to improve performance, fuel economy or emissions.
Two-stroke engines use a power valve system to get similar results to VVT. Replacing the oil and filter using the proper oil viscosity for the engine. Repairing or replacing the wiring to the camshaft oil control valve for bank 1 exhaust camshaft.
When the solenoid goes bad , something happens so there is inadequate or no current to the starter when you turn the key. And that's what happens when a solenoid goes bad — the engine won't turn over. An oil control valve also referred to as a VVT solenoid is an important component of a vehicle with a variable valve timing VVT system. The existence of the system aims to control the performance of the engine utilizing two methods to retard and advance camshaft angle.
The VVT solenoid is the electrical part that gauges the engine's needs based on oil pressure. It then accordingly controls the camshafts which are the mechanical parts responsible for opening and closing engine valves. What does the variable valve timing solenoid do?
