Bank 2 is the drivers side of the engine in your Mercury Mountaineer
Sensor 1 is between the engine and the catalytic converter ( upstream )
Sensor 2 is after the catalytic converter ( downstream )
Bank 1 is the passenger side of the engine in a Mercury Mountaineer ( V6 + V8 ) Sensor 2 is after the catalytic converter ( downstream )
Bank 1 is the passenger side of the engine in your Mercury Mountaineer ( V6 and V8 ) and bank 2 is the drivers side of the engine
Bank 2 is the drivers side of the engine in a Mercury Mountaineer Sensor 2 is in the exhaust after the catalytic converter ( downstream )
Bank 2 is the drivers side of the engine in your Mercury Mountaineer ( V6 + V8 ) Sensor 1 is in the exhaust close to the engine before the exhaust enters the catalytic converter
On a 2002 Mercury Mountaineer ( V6 and V8 engines ) Bank 2 is the drivers side of the engine Sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter
On a 2000 Mercury Mountaineer ( 4.0 V6 and 5.0 V8 ) Bank 2 is the drivers side of the engine Sensor 1 is close to the engine BEFORE the exhaust enters the catalytic converter Sensor 2 is AFTER the exhaust has passed through the catalytic converter

No , the 5.0 liter V8 engine in a 1998 Mercury Mountaineer has ( 1 ) timing CHAIN
On a 1997 Mercury Mountaineer ( V6 and V8 ) Bank 2 is the drivers side of the engine
your bank one sensor is the o2 sensor on the exhaust manifold bank one means that it is on the same side of the engine as the #1 cylinder (driver side for the v6 not sure on the v8)
If you have a 1997 to 1998 Mercury Mountaineer or Ford Explorer with a V8 engine, you will have a 4R70W transmission.
For a 1997 Mercury Mountaineer ( 5.0 liter V8 ) ( there are a total of 4 oxygen sensors , 2 sensors that are used with the PCM to adjust the fuel ratio that are nearest the engine on both sides , and 2 sensors that are also called catalyst monitors because they are in the exhaust after the catalytic converters ( downstream sensors ) On the passenger side of the engine in a Mercury Mountaineer ( Bank 1 ) Sensor 1 ( upstream sensor ) and Sensor 2 ( downstream sensor ) On the drivers side ( Bank 2 ) Sensor 1 ( upstream sensor ) and Sensor 2 ( downstream sensor )
