I have a 97 civic dx with a ex VTEC engine and a P2P ecu for the motor. It’s throwing codes for secondary o2 sensor switch that body style only came with one and a fuel tank pressure sensor which it doesn’t have either. It runs and drives fine but the ecu is throwing codes for something it doesn’t have. I tried a chipped p28 ecu with a jumper harness and the check engine light went off but I can’t communicate since it’s converted to obd1 and I have a obd2 port. Is there anyway to fix it so it can communicate and clear the light?
