Today while driving to work my check engine light came on. I wasn't driving my car hard. I stayed under 4k rpm the whole trip. When I got to work I used a wire to get the code and it flashed code 22. I looked that up to be: "VTEC Oil Pressure Switch defective circuit or unplugged / defective oil pressure switch" Has anyone on here had that code? What ended up being the problem? I didn't wan't get into high rpm so I don't know if VTEC would have engaged. And I have recenty switched to Mobil 1 15w50 racing oil becuase my valve stem seals are kinda bad. Could that be messing with the VTEC?
