System Fault Help

My check engine light just came on and a few miles later the "exhaust fluid system fault" also came on. I plugged in my scanner and these codes came up:

P2479 b1s2
P2033 b1s2
P050E
P0231 b1s2

I'm assuming these mean bank one sensor 2 is bad. Can anyone verify? I don't remember all these codes when the #4 sensor went bad.

Thanks in advance!

P050E - Cold Start Engine Exhaust Temperature Too Low
P0231 - Fuel Pump Secondary Circuit Low
P2033 - Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 2
P2479 - Exhaust Gas Temperature Out of Range (Bank 1 Sensor 2)

Thanks, I changed sensor #2 and everything seems to be okay now. My scanner still shows P2033 and the word "permanent" is right next to it. I assume it stays forever?

The exhaust fluid was mostly full it would only take a gallon, but the light went off after about five miles. Is there a simple fix for this?

Might be the sequence you tried to clear the code...or your scanner is not capable of clearing it.

Son of a Gun, I just had my engine light come on again. This time code P247A. The list says it's sensor #3. This sensor looks a little different than the other three, can someone confirm? From what I can tell so far it's the one on top of the DPF.

Thanks again in advance!
