BANK 1 SENSOR 1 IS THE ONE IN THE EXHAUST MANIFOLD. BANK 2 SENSOR 2 IS BELOW THE CATALYTIC CONVERTER.
P0171 SHOULD GO AWAY WITH A GOOD O2 SENSOR BUT DO CHECK FOR VACUUM LEAKS TO BE SURE. 3.1/3.4L ENGINES HAVE A BAD DESIGN INTAKE MANIFOLD GASKET, THE LEAK OIL, COOLANT, AND AIR.

bank 1 is the drivers side bank, so b1s1 would be the drivers side closest to the engine. if the truck is equipped with several 02 sensors then bank 2 or b2s1 would be passenger side closest to the engine. those are called upstream o2 sensors and the others downstream b1s2 and b1s2 b= bank 1= drivers side s=sensor 2=downstream. hope this helps.

hi yes it is, just unplug cable and unscrew sensor its that simple, if it was bank 02, sensor 2 that would be the one after the catalytic converter...hope this clears it up for you...

SOURCE: where exactly is o2 sensor
in the drivers side or the top of the exhaust manifold where it bolts up to the exhaust pipe back by the firewall. Sensor 1 is always before the catalytic converter. Sensor 2 is always after the converter

Tips for a great answer:
Oxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 1)
What does that mean? Essentially the same as P0136 and P0137, a P0131 code refers to the first oxygen sensor on Bank 1.
P0131 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 1 is located in front of the catalytic converter.
Symptoms There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination.
Causes A code P0131 may mean that one or more of the following has happened:
