Where is Bank 2 Sensor 1?

[Carolina Rauder]

Come on somebody help me out......

Bank 2 refers to the opposite side of the engine the 1st cylinder in the firing order is located. Sensor 1 refers to the 1st O2 sensor.

Funny thing is Bosch makes 85% of all O2 sensors on the market, the ones with the Bosch name pass the most stringent testing, the ones that fail are then sent back through the process, re-tested at a lower standard, passed, and sold as aftermarket. I know this because my wife runs the test line.

So can you get confirmation whether Bosch makes Motorcraft O2 sensors?

Bank 2 Sensor 1

Ok so I know that sensor 1 is before Cats. Which side is bank 2 driver side or passenger side?

The last set of Motorcraft O2 sensors I bought looked identical to a new set of NGK sensors I had. And I do mean identical. Currently I'm running NGK O2 sensors in all three of my Panthers with no problems at all.

Bank 2
Driver side or Passenger side?

[javiloh]

The rear sensors are Ford part # 5W6Z-9G444-BA

[Carolina Rauder]

I need to know which Sensor to change out!?! My print out read Bank 2 Sensor 1...... Someone PLEASE tell me which sensor that is FRONT/REAR? DRIVERSIDE/PASSENGERSIDE?

[STEPS]

bank 2 is the passenger side

[RF Overlord]

bank 2 is the passenger sideNo. Bank 1 is always the side with the #1 cylinder, which on the Ford 4.6 is on the passenger side, therefor Bank 2 is the driver's side. Sensor #1 is the one closest to the exhaust manifold.
