my friend just helped me install a vafc on my 99 gsr..after the installation..everything was fine..the thing was we thought vtec engages at 5500 so we set it to 5500..when it really engages at 4400 ..after driving it a while and hitting vtec..it threw a cel..22..can anyone confirm that 22 is vtec malfunction..what should i do now..im really worried that i might really damaged my car..after the cel came on..we disconnected the battery to reset it so the cel would go away..now when i reach around the vtec rpm doesnt feel like it engages anymore..when i use to hit it..it can hear the diff tone in the exhaust..now it stays the same thoughout the rpm band..any help on where to go from here..i set it back to 4400 now and the codes off for i disconnected battery..

 

CEL 22 is the VTEC Oil Pressure Switch

 

code 22 is a VTEC Oil Pressure Switch defective circuit or unplugged / defective oil pressure switch

 

so since thats the problem..what do i do and where do i go from here to fix that problem? thanks

 

Check your wiring again to make sure you installed the VAFC properly.

 

are you suppose to connect the blue wire.? the vtm signal one..that seems to be the only one that the diagram doesnt say to connect..everything else is soldered into place..?i was told by some to connect it and the problem will be fixed but others say dont because if i do vtec wont engage

 

I have the same problem for about 5 months and i cant seem to find out what it is i bought a new vtec pressure switchy todya it should be in in about three day. has anyone else had this problem and the vtec presure switch didnt work where would i go from there?

 

Yes, connect the blue VTM wire. Apexi released updated instructions that state to connect this wire if you experience problems. I didn't hook it up at first because I had the old instructions ... threw a code. Hooked up the VTM and all problems were solved.

 

I hook it up as well but im still throwing a code 22. I unhook my vtec pressure switch and then reconected it and my car was fine all weekend but now im throwing it again.

 

i was told the vtm hooked up would make vtec not engage? is that not true?
