Where is the location of 02 Sensor on a 1996 S10 4x4 4.3 liter for example where is Bank 1 Sensor 2 in the Exhaust system?
Bank one is usually the left side of the motor and sensor 2 would be the one past the converter.
There are two oxygen sensors one is called the upstream oxygen sensor located in the exhaust manifold and one downstream directly behind the catalytic converter. I think the one you are looking for is mounted in the exhaust manifold sometimes referred to as bank 1 and sensor 1 being the first in the exhaust system. Hope this helps you.
They should be in the exhaust system close to the engine ( either in the exhaust manifold outlets or the exhaust pipe ) before the exhaust enters the catalytic converters Bank 1 is the passenger side of the engine and sensor 1 is the upstream sensor Bank 2 is the driver side of the engine and sensor 1 is the upstream sensor on that side
