Check the What This Fits tab for more fitment details. It allows for more optimum engine performance, reduced emissions, and increased fuel efficiency compared to engines with fixed camshafts. ![]() This part, 237963RC0A, fits Nissan Altima 2015-2022. Variable Camshaft Timing ( VCT) is an automobile variable valve timing technology developed by Ford. ![]() Shop genuine Nissan Valve Timing Solenoids online and head to a trusted service center for installation. Variable Valve Timing (VVT solenoids) or so-called oil control valves are one of the greatest innovations in the automotive industry. Getting regular oil changes is a great way to help avoid this issue entirely. The purpose of variable valve timing (VVT) is to help increase the engines volumetric efficiency and limit the exhaust gasses produced by the vehicle. Oil can clog the passageway from the solenoid to other engine components and prevent it from working correctly. One of the most common reasons for Engine Variable Valve Timing (Vvt) Solenoid problems is dirty engine oil. You may need a new Nissan timing solenoid if your engine starts rough idling, gas mileage gets noticeably worse, or your check engine light illuminates. How can you tell when it's time to replace the Engine Variable Valve Timing (Vvt) Solenoid? Watch for these potential symptoms because in the worst case, a broken or worn Engine Variable Valve Timing (Vvt) Solenoid can lead to engine failure. When the Nissan Engine Variable Valve Timing (Vvt) Solenoid functions like it should, it helps support engine performance and fuel efficiency. It takes note of the engine load and speed and regulates the oil flow accordingly. You'll find the Engine Variable Valve Timing (Vvt) Solenoid inside the timing system. The variable valve timing solenoid is new technology found in select vehicles as part of the VVT system. Replace early to help avoid engine damage.May need to be replaced if Check Engine light is on or engine performance.Helps manage engine oil flow based on speed and load.Standard Ignition engine variable valve timing (. A tarnished actuator may not release or engage. We manufacture engine variable valve timing (vvt) solenoids for virtually every automobile on the road today. The solenoids, control valves, and passages become clogged with a gel from neglected and unchanged oil. The solenoids and actuators used to control these systems can become clogged or have electrical issues. A faulty VVT solenoid or valve could result in a rough idle or poor high-speed engine performance. Test the solenoid and its circuit for resistance with an ohmmeter. As a result, manufacturers have designed engines without EGR valves. Holding the exhaust valve open a little longer allows a small amount of exhaust to enter the chamber, reducing NO x formation. There are different ways to accomplish this Some systems change the timing by opening the intake valve sooner, allowing more air-fuel mixture to enter the combustion chamber.Īlternating between two camshaft lobes for each cylinder provides a smooth idle, low-speed, and high-speed performance. ![]() Variable valve timing delivers smooth idle and low-speed operation and performance and horsepower at higher RPMs. The national cost for a variable valve timing solenoid replacement in 2023 is between 224 and 530 with an average of 377 Save 20-200 on your auto. Most late-model vehicles have some form of (VVT) variable valve timing.
