My engine light has come on so I ran some codes to see what the issue is. Here is the code;

P2272 O2 sensor signal biased/stuck lean (bank 2 sensor 2)

Does this simply mean that the O2 sensor is bad, or could something else cause this to react this way?

I would say you may have a bad vacuum leak that is feeding the front side of the intake manifold.

Exhaust leak near O2 sensor
Contaminated or failed HO2S2 (Sensor 2)
HO2S2 wiring/circuit problem
Loose installation of HO2S2
Fuel pressure incorrect
Faulty fuel injector
Engine coolant leak
Faulty purge solenoid valve
From the internet search for P2272.
