The oil pressure is influenced by wear or high mileage and a lack of vehicle maintenance.Ĭheap, low grade oil – The quality of the oil (view on Amazon) is very important to your engine’s performance. The VVT solenoid is electric and uses solenoids that are oil pressurized. No matter how expensive, any vehicle is subject to problems due to wear and tear over time. The components of the internal combustion engine get dirty with deposit buildups over time and passages become blocked after excessive use. Wear and tear– Excessive wear on a vehicle combined with time can cause anything from worn bearings to reductions in the original flow restrictions.
Here are the most common causes of VVT solenoid failure: The VVT solenoid is so important that when it fails, many other parts are in jeopardy. The engine temperature and flow of oil has to operate a specified level. So, why would a VVT solenoid ever fail? The parts to your engine move fast in very harsh, heated conditions. The design and manufacture of VVT solenoids are high precision, high quality processes. Thus, the VVT solenoid opens the exhaust valve as wide as it can go for as long as is needed to maintain the speed and pressure. The engine must also expel a larger amount of exhaust. The VVT solenoid must open the valves as wide as they can go and for as long as is needed to achieve a large amount of power. More specifically, the engine needs more of the air/fuel mixture. When an engine must produce enough power to run uphill at a high speed, more fuel is required. Less fuel is burned which promotes fuel efficiency. The exhaust can be retained to minimize the amount of air that enters the engine during the idle. Thus, the engine requires less intake of air. When the engine is idling, it does not require as much fuel. Engine valves regulate the amount of air enters the engine and how much exhaust leaves. The valve controls how long the different valves in the engine remain open based on the engine requirements. The VVT solenoid regulates the flow of oil based upon the engine load and engine speed.
The valve measures the engine’s needs based upon the oil pressure using camshaft phasing sockets and oil pressurized solenoids to regulate the timing of valve lift events within the RPM range. The VVT works by electricity to regulate the camshafts. The timing of the engine air/fuel intake is regulated by the phase angle and shape of the cams. The VVT solenoid is attached to the camshafts that open and close the valves near the cylinder head block and the timing change or belt cover.
