Broken Oxygen Sensor - BMW 3-Series (E90 E92) Forum

bimmergixxer · 10-11-2012, 01:45 PM

My car threw a code about a bad 02 sensor and while replacing it, I found the problem was to be a broken connector that got wet inside and rusted out. Does anyone have a Bank1 post cat 4 pin connector so I can plug in my new sensor or can I just cut both connectors off and attach the wires together? Thanks.

The connector is used in the calibration of the sensor. People have spliced before and seem to be okay but I'd just buy a new O2 sensor.

The connector for the sensor is fine and I have a new oxygen sensor but I am curious about the connector that connects to the 02 connector
