Sensor 2 is the one after the catalytic converter. Located strait down under intake.
closest sensor to the motor
Is this bank 2 sensor 1 or sensor 2?
The bank 1, sensor 3, O2 sensor would be the O2 sensor post cat.
On a Ford Expedition ( 4.6 and 5.4 ) Bank 1 is the passenger side of the engine Sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter Sensor 2 would be AFTER the exhaust has passed through the catalytic converter
3, sensor 1 bank 1, sensor 2 bank 1, sensor 2 bank 2
From what i read, the bank one sensor is on the driver's side of the exhaust manifold. Bank one refers to the first cylinder.
It is the sensor below the catalytic converter.
This would be the sensor after the catalytic converter.
bank one is the rear head, sensor 2 would be the lower one
Bank one sensor one oxygen sensor
The one after the catalytic converter.
That is the O2 sensor behind the catalytic converter.
