Bank one sensor two refers to the oxygen sensor. The bank one sensor two oxygen sensor is on the front side of the engine, after the catalytic converter.
Your in luck...that should be the oxygen sensor in the exhaust manifold at the front of the engine compartment. Bank 2 is the bank of cylinders that does NOT contain the #1 cylinder. That bank is bank 1. Sensor 1 is the oxygen sensor upstream of the catalytic converter, and sensor 2 is the one after the cat.
Bank one is the side of the engine with cylinder #1. Sensor 2 is after the catalytic converter.
The oxygen sensor bank 1 is located in the exhaust manifold. The oxygen sensor bank 2 on the 1996 BMW 328is is located in the head pipe.
On a ford e350, the bank two sensor two is on the drivers side. The sensor is the one behind the catalytic converter.
If it has a bank two, It would be on the passenger side. I have a 1994 K2500, it only has one oxygen sensor.
Bank 2 Sensor 2 is passanger side after cat.
Replace it. Sensor 2 is the one AFTER the catalytic converter.
bank #1 sensor #2 is the oxygen sensor that is past the catalytic convertor(some mechanics call it the downstream sensor)the sensor is located between the convertor and muffler you can use a 7/8 wrench or a oxygen sensor socket if you have one
The exhaust system has two banks. Each bank has two oxygen sensors. Bank one is on the driver's side. Oxygen sensor 1 is between the exhaust manifold and the catalytic converter. Oxygen sensor 2 is behind the converter.
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.
where is the oxygen sensor location on a 1998 explorer bank 2 sensor
