I have a 92 prelude SI with a 2001 2.2 vtec in it. I bought it with the swap already done. I jumpered the connector to access the codes and I got Codes 1,21, and 22.... I guess 1 is the oxygen sensor circuit fault, 21 is the vtec oil pressure switch, and 22 is the Vtec actuator/solenoid.... I need to get my check engine light to stay off because I have to pass emissions soon. The engine runs great and vtec works and everything. I dont know where to start with this because the original harness and computer were retained and i guess he put some kind of chip in it to allow vtec to be used. I would really like to find a page about how to put an OBD2 engine in a OBD1 car because he kept it OBD1 and I want to be able to fix this. I assume since the CEL is on, the computer is using preset values for the air/fuel mixture, so that can't be good for extended use. I have put over 2000 miles on it since I got it and have had no problems. Pleae someone point me in the right direction. I am a Jeep Tech so I do have knoweledge to some extent of electrical, but I would like to see from a conversion article what wires he actually ran and where they go. Thanks alot guys!

P.S
I'm also have some oil consumption. The engine has around 40k on it and no leaks whatsoever, and no blue smoke... I go through about 1 qt every 1k miles... this seems alot, could it be valve seals seeping by? or is my CEL causing a rich mixture which is washing the pistons off and then it is getting by the rings? any ideas?

 

no one knows whats going on here?
