I'm battling this same problem on 04 LX. I just bought car and believe someone has worked on it before. It was dang near finger tight when took old one out. It was densco brand, would that possibly been one from factory? Or would it have had different brand?

. I have nothing to compare it too but it doesn't look bad as far as all chalked up.

The P1157 indicates an open/short in the wiring this is why the code is different. Usually a new O2 sensor fixed it because the issue is at sensor. There is something wrong with the wiring in the line or you have a bad sensor. Denso seems to be the only ones that work correctly on these cars but sometimes you can get a bad one. Have you gotten a replacement.
ive not found the problem you know which wires does.and the ohms or volts they put out thanks
