92 civic vx with b18b cel for code 41 primary o2 senor heater, already repinned at the shock tower. Tried 2 new sensors but cel still comes on. Anything else i can try?

 

Make sure the wiring is in good shape and intact for the o2 sensor first. If the ECU isn't getting any input from the new o2 sensor it's very likely shorted wire or something like that. Once you check the simple stuff like that then you can get back to pinpointing the issue

 

I just get a 10w resistor and put it inline on the heater circuit. The o2 heaters never last but the o2 works fine for years after the heaters fail, from my experience...

 

Okay ill try and do that asap when i get some free time see if theres any shorts or anything. Here is a picture on the connector D see if its in the correct slots.
