Bank 1 sensor 1 would be threaded into the exhaust pipe directly after the exhaust manifold on the drivers side of the engine.
where is the oxygen sensor location on a 1998 explorer bank 2 sensor

Bank 1 is the same side as cylinder #1. Sensor 2 is after the catalytic converter.
Bank one is the side of the engine with cylinder #1. Sensor two is after the catalytic converter.
Bank one is the side of the engine with cylinder #1. Sensor two is after the catalytic converter.
2: 1 (Bank 1 Sensor 1) Upstream of the Catalytic Converter on the rear Exhaust Manifold & 1 (Bank 1 Sensor 2) Downstream of the Catalytic Converter on the Exhaust Pipe.....
Bank 2 is the passenger side head. Look at where the exhaust pipe bolts to the exhaust manifold there will be a o2 sensor just below it screewed into the exhaust pipe, that will be #1 02 sensor.
