15811-R40-A01 is the single Pressure Switch, Spool, Solenoid.
15811-R41-L01 is the dual Pressure switches, Spools, & Solenoids
Why? Because I heard that the spool's oil control valve is responsible for "leaking" and causing pressure in the actuator to "leak down" causing the start up rattle. Is that not the case?
Also, a highly respected member here, who wrenches on cars himself, highly suggested replacing the spool valve.
I ordered both of them because I'm not 100% sure which valve I have (I needed to order right away and the mechanic had the car locked up in his garage). So I'll just send back the valve (or both) that I didn't use.
VCT & VTEC are 2 completely separate systems......
*The VCT is comprised of a Control Solenoid with a built-in spool valve & a the VCT Phaser/Actuator (Intake Cam Gear).
*VTEC is for Primary & Secondary Rocker Arm control....While this system has it's own problems, It's a lot more reliable than the VCT system & has its own DTC's/Monitor's via the Pressure switches.
