same way you replace any sensor.
The bank 1, sensor 3, O2 sensor would be the O2 sensor post cat.
Bank 1 Sensor 1- driver's side exhaust pipe Bank 1 Sensor 2-right before catalytic converter Bank 1 Sensor 3- right after catalytic converter Bank 1 Sensor 1- passenger side exhaust pipe Bank 1 Sensor 1- driver's side exhaust pipe Bank 1 Sensor 2-right before catalytic converter Bank 1 Sensor 3- right after catalytic converter Bank 2 Sensor 1- passenger side exhaust pipe
3, sensor 1 bank 1, sensor 2 bank 1, sensor 2 bank 2
Bank 1 sensor 1 would be the first sensor on the drivers side exhaust pipe close to the engine. Bank 1 sensor 2 would be the sensor just before the cat converter. Bank 1 sensor 3 would be the sensor just after the cat converter. Bank 2 sensor 1 would be the first sensor on the passenger side exhaust pipe.
Bank 1 sensor 3 should be the one after the catalytic converter.
passenger in front of cat but normally when one o2 sensor gos the other 3 are not far behind i would replace them all
Bank 1 is drivers side where number 1 cylinder is. Sensor 3 is post cat/converter, drivers side
bank 1 means cylinder 1-3 side, sensor 2 means the sensor after the catalytic converter.
Bank 1 sensor 3 would be the O2 sensor after the catalytic converter.
That would be the O2 sensor after the catalytic converter. This sensor monitors the efficiency of the catalytic converter.
That should be the sensor located after the catalytic converter.
That would be the sensor after the catalytic converter.
