Review on High-Quality 15810-RAA-A03 VTEC Solenoid Spool Valve with Oil Pressure Switch & Gasket - Perfect Fit for Honda Accord, CR-V, Element, Civic Si, Acura RSX - Direct Replacement for 15810-PNE-G01, 15810-PPA-A01, 15810-RAA-A01 by Brad Blake

I have a 2006 Honda Accord that went into limp mode and was throwing code P2647. This usually happened after a night of sitting. First I tried replacing the gasket but that didn't change anything. So I decided to replace the whole unit instead of a sensor. I am writing this a week after installation. So far I haven't had any problems. The whole process took me about an hour. It's a bit frustrating because it's impossible to see what you're doing, but it can be done. Watch one of the many YouTube videos before trying and you'll be fine.
