15810-RAA-A03 VTEC Solenoid Spool Valve with Oil Pressure Switch and Gasket Compatible with

VTEC (which stands for Variable Valve Timing and Lift Electronic Control) is an electronic and mechanical system in some Honda engines that allows the engine to effectively have multiple camshafts. As the engine moves into different rpm ranges, the engine's computer can activate alternate lobes on the camshaft and change the cam's timing. In this way, the engine gets the best features of low-speed and high-speed camshafts in the same engine.

• 【Replaces OE】- VTEC Solenoid OE# 15810-RAA-A03, 15810-PNE-G01, 15810-PPA-A01, 15810-RAA-A01, 15810-RAA-A02, 917-224.
• 【Compatible】- VTEC valve compatible with 2.0L 2.4L
• 【Function】 - The VTEC system provides the engine with valve timing optimized for both low and high RPM operations. The VTEC solenoid actually allows oil to flow to the internal galleries of the overhead camshaft. This means that the housing of the solenoid is holding back full engine oil pressure. A spool solenoid valve can direct the flow of hydraulic fluid. The valve is made up of spools that rotate or slide to block and open channels in a hydraulic system.
• 【Common symptoms】- If your vehicle won't go past 3000 RPM, a check engine light (CEL) with code P2646 or P2647 shows up on your dash or dirty motor oil; roughness of idling engine; fuel efficiency is reduced. You need to replace your VTEC Solenoid Spool Valve in time.
• 【Quality & Installation】- solenoid utilizes aluminum valve bodies that are surface-treated to create micro finished surfaces for increased wear resistance, means you will get a fairly reliable solenoid assembly to perform excellently under all engine operating conditions. The spool valve solenoid assembly can easily be located inside the engine bay behind the engine on the passenger side of the vehicle and can be removed by removing 3 bolts.
