It's O2 switching on bank 2 sensor 1. See below for a technical description...
The PCM continuously monitors the Heated Oxygen Sensor (HO2S) activity for 100 seconds. During the monitor period the PCM counts the number of times that the HO2S responds from rich to lean and from lean to rich and adds the amount of time it took to complete all transitions. With this information, an average time for all transitions can be determined. The PCM then divides the rich to lean average by the lean to rich average to obtain a ratio. A DTC P1154 sets if the HO2S ratio is not within range.

Looks like you're in a C5 there - check under the front around the radiator and see if you sucked up a grocery bag or something and it's blocking your radiator.
