03 Honda Element that my wife has been borrowing has a P2646 code for rocker arm actuator blah blah. I don't want to give it back broken. Looked online and followed the diagnosis proceedure. It was low on oil by about a quart so I filled it. No good. Replaced the VTEC oil pressure sensor. No good. Replaced the VTEC solenoid unit. No good. Tested the ECM pins. Tested OK.
Uh... what next?
In reply to curtis73:
What's it doing? What's the complaint besides a CEL?
So, VTEC's NOT kickin' in, y0?
^ Common problem. Just add more vtac fluid.
Not doing anything unusual, just the code. Drives fine. We haven't been borrowing it long enough to notice if the engine operation is different.

With no intent to be devious or dishonest, disconnect the battery and let the ECU re-set itself.
Inform the owners; let them know what happened and what services you performed (out of your own pocket).
It's highly doubtful anything your wife did contributed to the problem; it's a wrong place, wrong time issue. Hopefully, the owners will recognize it would have happened, regardless of who was driving.
I'm not overly worried about it. Its a long-time family friend we're borrowing from and they know less than zero about cars. In appreciation for letting us borrow it I thought I'd get it taken care of (since they aren't letting us pay them for using it) ... and since I work at a repair shop and I get parts for wholesale it isn't really much out of my pocket.
I'll try the ECU thing. I read somewhere about updating with the latest software for the ECU? Any truth to that?
