Uh, yeah. There are 4 O2 sensors: two primary sensors in the headers which sense the A/F ratio and play a major role in the way the car runs as the ECU uses that A/F information to adjust both cylinder banks fuel/timing to maintain an optimal A/F ratio. The two o2 sensors that are in the cats are only there to monitor the condition of the converters, basically to make sure they are present and doing their job.

To access the A/F ratio, you can use OBD 2 live monitors.
