I need the location of oxygen 2 sensor on 96 Maxima

bank 1 refers to the side of the engine. on a four cylinder there will onlyu be a bank one. a v-6 will have a bank 1 and a bank 2. Bank 1 will be on the same side of the engine as cylinder number one. Bank 2 will be the opposite side. Sensor 1 is always before the catalytic converter. Sensor 2 is always after the catalytic converter.

So , for example, if your looking for Bank1 Sensor2 it will be in the exhaust pipe after the cat on the same side as the number one cylinder.

Cant find base1 sensor2 on a 96 ford explorer 6 cylinder 4 wheel drive

It's called bank, not base. On a v6 or v8, each side of the engine is called a bank. Bank 1 is always the side where the number 1 cylinder is located. On Fords, number 1 is on the right bank or side, the right as if you were sitting in the vehicle, so well, the passenger side.
Sensor 2 is the oxygen sensor in the exhaust stream after the catalytic converter (somebody recently called it the cadillac converter!). You have two oxygen sensors on the right bank, one before the cat and sensor 2 is after the cat. The only purpose of sensor 2 is so the computer can monitor the efficiency of the catalytic converter. It compares the readings from sensor 1 and sensor 2. Sensor 1 information is how the computer adjusts fuel trim.

Bank 1 o2 sensor 1999 honda accord lx v6, i need the location to change it. i can not find it in the front of my car

Bank 1 is at the back of the engine compartment next to the firewall. You'll need to know if you need to change (bank 1 sensor 1), or (bank1 sensor2). Sensor 1 is located in the exhaust system between the rear cylinder head and the catalytic converter. Sensor 2 is after the cat in the exhaust system after the cat.

2003 ford escape p 136 trouble code what is it and how do i repair it

If the code is P0136 then the code is 02 sensor (bank 1 sensor2) malfunction. Rear sensor.
Inspect wiring, inspect connection and pins, and if that stuff checks out then you may need a 02 sensor.

Location of the bank 1 sensor 2 O2 sensor on a 2001 ford escape

B1 means the sensor is located on the same bank of the engine that has the #1 cylinder. B2 is located on the opposite bank.
S1 means the sensor is located BEFORE the catalytic converter
S2 means the sensor is located AFTER the catalytic converter

You didn't say which engine you have, so I've included the diagrams of both 4 cyl and 6 cyl so you can see the banks
