Question about Dodge Dakota
No idea as no vehicle stated but if unsure then use a multi meter to determine which sensor isnt working by testing for a resistance across the heater wires and a voltage varying between .15 to .085 volts on the other two wires

Bank 1 is the same side as cylinder #1 and bank 2 is the same side as cylinder #2. Good luck and hope this helps.

is your vehicle equip with a v6 engine? if so it mean when standing in front the vhicle the exhaust on your right is on bank 2 & the o2 sensor should be mounted there

The 1.8 is a 4 cyl. engine . it has only 2 oxygen sensors . Nissan engine controll systems devides its EGO sensors into banks . Bank 1 is the upstream (top before the catylyctic converter) . Bank 2 is the downstream (after the cat. conv.) I recomend you change both for emissions reasons

The first and most obvious thing is to replace the O2 sensors. With age, they deteriorate and can give inaccurate readings which in turn will throw off the remainder of the fuel/ignition management system.
It has been actually recommended that they be replaced as part of a 'tune up" because even if not completely failed or out of range enough to trigger a dash light or code, they can drag down your fuel mileage. With no other codes showing, it's likely that is the problem.
That said, the O2 sensors will also react to other faults in the system such as a bad injector etc. There is no good way to tell though unless you replace them first (the sensors not the injectors).
There are two different grades of sensor...the cheaper "universal" type that requires you to put the wires in the correct positions and assemble the plug and one that has the plug pre-assembled, which is specific to your system. I recommend you get the pre-assembled one to avoid making any wiring mistakes. Always make sure that the wiring is secured away from any hot items and also away from moving objects such as your driveshaft.

Air/Fuel Sensors are mounted upstream of the catalytic converter. They are located on the exhaust manifold side of the catalytic converter (pre-converter - Sensors 1). Oxygen Sensors are mounted downstream of the catalytic converter (post-converter - Sensors 2). The catalytic converter has two chambers (left and right). Bank1 is left, drivers side. Bank2 is right, passengers side. The Bank2 Sensor1 sensor (Air/Fuel Sensor) is the one located on the 'right and ahead' of the converter. The PowerTrain Control Module (PCM) is reporting that the heater or circuit ( wiring / plug-in) of the sensor is malfunctioning.
