Just got a chipped P28 ECU and right away its throwing a code 22 which is the VTEC pressure valve?? I know that I need the VTEC oil pressure sensor wire disabled in my ECU, which I don't know if it was done or not now that it is throwing this code. I have a 97 TypeR motor in a 99 Si with the OBDII to OBDI jumper harness and a chipped P28 ECU. Any help to fix this problem would be much appreciated.

 

you can jumper proper voltage to the loose plug, tap out the housing and put in the correct switch, or go to a scrap yard or Acura to get the correct plate and sensor. They go on in about a minute.

 

Run uberdata to get rid of that code and have the added bonus of a standalone EMS
