I was driving to my girlfriends house this afternoon and I noticed that my check engine light turned on. I checked the code and it's a 22 which on an OBD-1 ECU is Vtec Oil Pressure Switch. The thing I don't get is that sometimes the light just comes on and stays on and sometimes it won't be on. For example, it came on 2 weeks ago for the same problem but then turned off and then just came back on today. The weather is just begining to change up here from about 85 degrees to 70 and lower so I don't know if that has anything to do with it. I've got an OBD-1 conversion on my 98 civic running a skunk2 chipped p28. Any suggestions on what to do ?

 

check your oil level.
