Greetings people...
I'm new here, but desperate. I have my girlfriend's 2001 Dodge Stratus with a 3.0L V6 that has an O2 heater circuit malfunction (Bank 2 Sensor 1). I have ordered a new pre-cat O2 sensor, but I cannot figure out which sensor it is. Can someone point it out to me in a picture or something? I'm hoping it will be an easy one for me to reach.

Thanks very much.
Alex
