Bank one sensor one is above the converter.
Bank 1 is the oxygen sensor either screwed into ,or above the catalytic converter. Bank 2 is below the catalytic converter.
Bank 1 sensor 2 is the sensor after the catalytic converterBank 1 sensor 2 is the sensor after the catalytic converter
That is the oxygen sensor screwed into the downstream side of the catalytic converter.That is the oxygen sensor screwed into the downstream side of the catalytic converter.
It's the sensor before the catalytic converter. The 1500 has 1 behind & 1 after the cat
It is the sensor below the catalytic converter.
That is the O2 sensor behind the catalytic converter.
bank 2 is passenger side, sensor 2 is rear sensor (after catalytic converter)
Upstream, driver side.
Bank two sensor two on a 2002 Ram is passenger side, after the catalyst.
02 sensor circuit slow response bank (bank 1 sensor 1)
Passenger side exhaust
