Well, in all the trouble shooting I did for a code 48 CEL I bought a new O2 sensor to fix it. The car already had a fairly new on installed on it when I bought it but was not sure if it was the correct one. Ended up being a bad connector on my wiring harness so now I have an extra O2 sensor with about 500 miles on it. This is a 5-wire O2 made for a 92-95 Civic VX Federal P07 ECU. I paid $170 plus shipping for it but would take $150 shipped or best offer. Let me know if your interested.
