drivers side before the cat conveter.
YES
Bank 1 is the drivers side of the engine. Sensor 1 will be the first sensor that is screwed into the exhaust pipe that is the closest to the engine/exhaust manifold.

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
location bank 1 sensor 1
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.
Bank 1 (one) is the side in front of car (Bank 2 is rear, firewall side) 02 sensor 1 is upstream, on exhaust manifold (02 sensor 2 is downstream, by cat. conv.)
