Banks?

[ChiTDI]

'03 Ford 150 V6, CEL code gave me O2 sensor for
Bank 2 sensor one.
What is the configuration of the banks? Passenger/driver side?
There are four sensors, two before the Cat, two behind.
My thinking is the bad sensor is in front of the cat on the passenger side. Sound right?

Bank one is always where cylinder one is on a Ford. And is when looking at the front of the engine (belts, crank pulley) the left side.

From the factory service manual...

Bank one is the RH side (LH side when looking at the engine)
Bank two is the LH side (RH side when looking at the engine)

Your code is for the sensor on the LH side of the engine before the cat.
