Hi everyone, I am trying to get my check engine light off on my 2003 Saab 9-3 Linear. I am down to 1 Code that needs to be resolved. Autozone scanned the computer and it came up with Code P0037 heated Oxygen Sensor Heater Control Circuit Lower Bank 1 Sensor 2.

This is obviously an o2 sensor... when ordering the part I need to know if the 2 o2 sensors are the same or different. I can not find a clear answer for this. I'm guessing this is the sensor towards the back after the cat, but not sure. If anyone knows a part number or any information on this please post it.

Any tips or pics for install would be great as well if anyone has any.

Thanks
Scott

Yes this is the sensor after the cat. It has a different part number due to longer wires and the plug is slightly different so you can't confuse the two.
