My 95 Accord EX check engine light came on the other day. I took it to a local shop and they got a code 22 out of the ECU. I've figured out that its something to do with the oil pressure switch. Can anyone tell me in plain english what could be wrong and how severe this error is? Thanks in advance.

 

VTEC Oil Pressure Switch
defective circuit or unplugged / defective oil pressure switch
probably not that serious, just plug the connector for the oil switch back in or buy a new one and replace it
