Review on Benefast VTEC Solenoid Spool Valve: Timing Oil Pressure Switch & Gasket 🔧 – Honda Accord CR-V Element Civic Acura RSX Acura TSX – Replacement# 15810-RAA-A01 15810-RAA-A03 by Chris Beals

While the Honda VTEC Solenoid remains a reliable component, it does not last forever. Thick, dirty, or viscous oil can clog the phaser or solenoid. This is the main cause of these parts getting stuck. Thin oil can also cause premature wear of moving parts. An electronic solenoid can also fail if one of its wirings burns out. Replacing the VTEC solenoid is much easier and can be performed by an experienced technician.
