Want this question answered?
The bank 1, sensor 3, O2 sensor would be the O2 sensor post cat.
passenger in front of cat but normally when one o2 sensor gos the other 3 are not far behind i would replace them all
You did not specify which O2 sensor it is. Is it sensor 1 bank 1, sensor 2 bank 2, sensor 2 bank 1, or sensor 1 bank 2. There are four O2 sensors on a mazda 626
usually bank 1 is the bank with # 1 cylinder in it and sensor # 1 is the front o2 sensor(usually in the manifold). You will need a O2 sensor socket or a 22mm wrench or deep socket.
P0137 = O2 sensor circuit low volts (bank 1 sensor 2). Could be a faulty B1 S2 O2 sensor.
2001 Tundra v8 code P0135 is a o2 sensor heater circut( Bank1 sensor 1).
Bank 1 is the bank of cylinders that contain the number 1 cylinder. O2 sensor 1 is the first O2 sensor in the exhaust system between the engine and the catalytic converter.
Is this bank 2 sensor 1 or sensor 2?
Bank 1 is the bank of cylinders that contain cylinder 1. The O2 Sensor 1 is the O2 sensor located in the exhaust system between the cylinder head and the catalytic converter, also known as the "upstream" O2 sensor.

That would be the O2 sensor after the catalytic converter.
It is O2 Sensor Circuit Malfunction possibly (bank 2 Sensor 2) Yogi karki It is O2 Sensor Circuit Malfunction possibly (bank 2 Sensor 2) Yogi karki
