P2646 Solved K24 Honda Element Accord CRV

If you've ever suffered with your Honda being in limp mode (won't accelerate passed 55mph or 2800rpm). Then this is the video for you. After a lot of research, and 25 years of real world experience in the automotive field building race cars and doing general repair work, we've come to the fix, finally, for the infamous P2646 and P2647 code. Which is for the Spool valve solenoid or VTEC solenoid.

To make it easy there are three main causes. For all K24's, the first is the oil itself. For Element's specifically water intrusion plays a major roll in this code setting. And thirdly the oil pressure switch on the Spool valve could be leaking and the spool valve needs replacing.
