Ok, driving down the interstate, all of the sudden out of no where, CEL comes on. I was at a steady drive, maybe 60 mph, no acceleration really, just driving. Code 22, VTEC Oil Pressure Switch. I have unplugged the switch and the VTEC solenoid switch and checked the connectors, both look good, and I plugged back in. Reset CEL and still it showed up. Then I unplugged the oil pressure switch, and check for continuity, about 1.5 ohms at most, so great continuity, and then rotated key to acc. position and checked voltage, and got about 12 volts. So this means the wiring is good. So then I reset then ECU CEL storage, and rotated to the acc, no i did not turn the engine on, and the CEL came back on. So, now what? I know there is a small screen on the solenoid that can get stuff to clog it, but wouldn't it set the CEL 21, VTEC solenoid. If this is true, then obviously I just need a new VTEC oil pressure switch. I just need to make sure that the clogged screen wont set off the oil pressure switch CEL.

 

have you check your oil level?? what kind of condition is your oil in??

 

how is your oil level, i'd also recommend cleaning the mesh underneath the vtec solenoid.
