Anyone know if there’s a connector to bank 1 o2 sensor other than under the vehicle? I have a 2003 crv. I ohm’d out the heater and its working. I tested the leads from the car and am getting 12v on startup. OBD reader shows no activity and live feed shows activity on bank 2 but nothing on bank 1. I unplugged the sensor and tested the pins while running and was reading around 0.67V a couple minutes after running. OBD was showing 0.000v but bank 2 was around .855v I thought maybe a bad connection under so I probed the vehicle wires behind the connector and im getting the 0.67v. So my guess would be there’s another connection that’s bad or maybe ecu? I’m more familiar with domestic vehicles and ive always found the fault in a sensor or connector. Anyone ever run into this issue?
