Bank 1 On the passanger side sensors Sensor2 the bottom O2 Post CAT sensor
Bank 1 is the passenger side of your engine on your Ford Explorer Sensor 2 is in the exhaust pipe after the catalytic converter ( downstream )
Bank 1 is the passenger side of the engine on a Ford Expedition Sensor 2 is in the exhaust after it has passed through the catalytic converter ( downstream )
On a 1998 Mercury Grand Marquis : Bank 1 is the passenger side of the engine Sensor 2 is AFTER the exhaust has passed through the catalytic converter
Bank 1 is the passenger side exhaust pipe that leaves the engine and turns into your catalytic converter and extends to the muffler and ends as exhaust pipe on the passenger side. Sensor 2 would be downstream and behind or after the catalytic converter. Bank two is driver's side, and sensor 2 again is the sensor after the cat.

O2 heater circut malfunction Bank 1 sensor2. " rear oxygen sensor is bad"
Bank 1 is the bank that sits closest to the front of the vehicle. Bank one is the bank with cylinder # 1. You have 4 oxygen sensors, (bank 1 sensor 1, bank 1 sensor 2, bank 2 sensor 1 and bank 2 sensor2). Follow the exhaust from the head of bank 1. The first sensor you come to is sensor 1, the second is sensor 2.
Sensor 2 is the downstream sensor (after the catalytic converter). Bank 1 is the drivers side of the engine
It has two. One is before the catalytic converter (Bank1 Sensor1) and one after the catalytic converter (Bank 1 Sensor2)
