Hi everyone! I've been driving my '06 CRV for over a year now and have been encountering an issue with the P2646 code, and wanted to know what everyone's thoughts are.
Around March of last year, the check engine light (P2646), VSA, and one that I would describe as a triangle with an exclamation mark all turned on. I took it to the mechanic and they managed to fix some things and turn off the check engine and VSA, but the triangle with the exclamation mark light stayed on. After another 3 months, the CEL and VSA also turned back on, with the same issue. I took it to another mechanic, where I got the solenoid swapped and an oil change, and that seemed to fix the problem. Then a couple months later, the same 3 light turned and this time I took it to my local Honda dealer, where they changed the oil pressure switch and cleared the codes. Problem solved for another couple months. When they turned on again, I drove the car around for about a week and they cleared on their own. I added solvent to clear the engine of any sludge and then did an oil change.
Most of the time, the P2646 appears about every 3 months (2-3000 miles), but after this last oil change (switched from regular to synthetic) back in February, the CEL has been coming on more often. It turns on and may last a couple hours to a few days, and then clear and be okay for about a week, and repeat.
Many thanks in advance!
