1999 express van 1500
Bank 1 is the same side that the number 1 cylinder of the engine is on and location 2 is the after catalytic converter sensor.
Right side of the car after catalytic converter

lOOK UNDER THE REAR OF THE VEHICLE ABOVE THE SPARE TIRE ON A CROSSMEMBER BETWEEN THE FRAME RAILS.
SOURCE: where is the bank 2 sensor 1 located.
Oxygen sensors are always numbered like this:
Bank 1 sensor 1
Bank 2 sensor 1
Bank 1 sensor 2
Bank 2 sensor 2
some manufacturers use a kind of shorthand that reads different, but means the same thing:
Sensor 1/1 or O2s 1/1
Sensor 2/1 or O2s 2/1
Sensor 1/2 or O2s 1/2
Sensor 2/2 or O2s 2/2
Bank 1 is always the side of the engine where cylinder number 1 is located and, of coarse, Bank 2 is the opposite side.
On a 4 cylinder engine, there is only 1 bank and it is always referred to as Bank 1.
Sensor 1 is always the upstream sensor (The one located BEFORE the catalytic converter)
Sensor 2 is always the downstream sensor (the one that is located AFTER the catalytic converter.
Most GM engines have #1 cylinder located on the left bank, (or Driver's Side) of the engine,
So, the answer to your question would be that you are looking for the sensor located before the catalytic converter on the right (or Passenger Side) of the truck.

Start with fuel system. Listen for fuel pump humm at fuel tank No humm check wiring to pump for power. Then check for spark at plugs and wires. Remove wire from coil and hold near engine and see arch when you crank. No arch. Replace ignition Modular inside distributor cap or cap or rotor
SOURCE: where is bank 1 sensor 2 located?
A Bank indicates what side of your engine (the even numbered cylendars or the odd numbered cylendars) or all of your cylendars if you have an inline motor. sensor two i would hazard a guess is a knock, ping, or temperature sensor on the second piston back from the front on the even numbered side of the engine (or the second piston back from the front if you have an inline engine instead of a v-6)
Hope this helps!
Joe.
