Hello,
My daughter drives a 1992 Accord LX. Recently, it started lighting up the check engine light. It is currently a code 41, o2 sensor heater. I have chgd the o2 sensor 3 times, 3 different brands, and I still end up with that or a code 43.

I have chkd for power at the connector, and it is there.

I have read on the internet, where it could be caused by a poor connection in a connector plug located near the top of the strut, passenger side. I found that connector by separating the connector and rechecking for power at the 02 heater connector. It was clean and dry, but I blew it out, sprayed electrical connector cleaner on it, let it dry, blew it out again and reassembled. No help.

Anybody else go through multiple o2 sensors in a early 90's accord? What was the fix?

Thank you, Bob
