I have a 2003 Ranger Edge 3.0 V6 and I am getting a bank 1 sensor 2 O2 sensor failure on the scanner code. Can anyone tell me where this is located. I can see at least two sensors directly behind the exhaust manifold connection, but not sure which bank is one and where the 2nd sensor is located.

 

Bank#1 is the passenger side, the second sensor is the one behind the catalytic converter. Use either NGK or Bosch brand sensors as either is considered OEM, any other brands might not be satisfactory.

 

Thanks, already have the Bosch sensor.
