I found out this morning, per advanced auto, I need to replace my Bank 2 Sensor 1 O2 sensor. Which one is this? and does anyone have a source where i get one at a good price. I have a 2001 dodge stratus R/T 3.0L.... Thanks for the help.

 

the best price will be at a parts store not the dealer. even then they can be pricey. not sure how the 3.0 is set up but bank mean what side, other number is the sensor closest to the head. badstrat should know. good luck.

 

Bank 2 sensor one is the first sensor before the precat off the exhaust manifold near the firewall side of the car...
