Replacement for Variable Timing Solenoid — Fits 2015–2017 Nissan Altima Keep your Altima running smoothly by replacing a worn or failed variable timing (VVT) solenoid with a directfit replacement designed for 2015–2017 Nissan Altima models. This solenoid restores reliable oil control to the camshaft phasers so your engine maintains correct valve timing, smooth idle, and performance. Key benefits Restores proper valve timing control: replaces a faulty VVT solenoid to correct timing irregularities that cause rough idle, reduced power, or reduced fuel efficiency. Clears drivability issues: addresses common symptoms like stalling, hesitation on acceleration, or engine codes related to camshaft timing. Directfit replacement: designed to match the original part's form and mounting location for a straightforward installation—no modification required. Durable and reliable: built to withstand engine oil and heat exposure for longterm service life. What this part does (functionality) The variable timing solenoid meters engine oil pressure to the variable cam phaser(s), allowing the engine control unit to advance or retard camshaft timing as needed. Proper VVT operation improves lowend torque, rpm power, idle stability, and fuel economy. Compatibility Specifically for 2015, 2016, and 2017 Nissan Altima models equipped with variable valve timing. Intended as a replacement for the factory VVT solenoid in the listed model years. Confirm compatibility with your vehicle by comparing the part to your existing solenoid before . Key attributes Function: Controls oil flow to camshaft phaser(s) for variable valve timing operation. Fit: Directfit design for 2015–2017 Nissan Altima (matches OE mounting points). Construction: Enginegrade materials and seals designed to resist oil degradation and underhood temperatures. Performance: Restores stable cam timing actuation for consistent idle, responsiveness, and efficiency. Installation: Typically replaces the original solenoid without modification; recommended installation by a qualified technician or competent DIYer familiar with engine components. Common symptoms that indicate replacement is needed Check Engine Light with codes related to camshaft timing or VVT (for example camshaft position/actuation codes). Rough or erratic idle, especially after startup. Decreased fuel economy or noticeable loss of lowend torque. Engine hesitation or stalling during acceleration. Use cases / applications a failed VVT solenoid after diagnosis of cam timing codes or visible oil leakage from the solenoid area. Preventive maintenance when experiencing intermittent timingrelated drivability problems or during routine engine service to restore consistent VVT operation. project for a 2015–2017 Nissan Altima undergoing cylinder head or timing component service where the solenoid is being replaced as part of restoring proper engine timing control. Installation notes and tips Always disconnect the battery and follow vehicle manufacturer safety procedures before beginning work. Verify engine compatibility and compare the replacement part visually to the removed solenoid prior to installation. Clean surrounding area to prevent contamination of the oil passages; ensure electrical connector and sealing surfaces are clean and secure. If unfamiliar with VVT system service, consult a professional technician to ensure correct installation and calibration. What you receive One replacement variable timing (VVT) solenoid intended for 2015–2017 Nissan Altima models. This replacement VVT solenoid is a practical solution to restore proper camshaft timing control and improve drivability for affected Nissan Altima vehicles from 2015 to 2017.
