I went to the mechanic to get my oil change and I had him check my CEL again...The following codes were pulled:

P0138(0510) - Rear O2 Sensor
P0140(0512) - Rear O2 Sensor

P0158(0313) - Rear O2 Sensor-B2
P0160(0315) - Rear O2 Sensor-B2

I just wanted to know why there were multiple codes pulled for the same thing? Both of them were Rear Bank 2. So I just have to replace that ONE sensor right?
