OK I did research and could not find anything!!! I have a 1996 ek4 hatch Just put a
b20 v-tec and all the wiring is good but it keeps throwing the oxygnen sensor code it says sensor 1 bank 2, witch is the one behind the cat right? It has a brand new o2. At first I thought it was the harness but i wired it directly to to the ecu to be safe and still throwing code I tried splicing it to the other o2 and still gives me the o2 code. I put a obd1 ecu with a jumper harness and still gives me the code I don't know what to do any ideas!!! I was using a obd2 scaner to the diognostics code.
