Default CEL after replacing O2 sensors

I've got a 2004 T&C 3.3 front wheel drive that I just replaced both O2 sensors on. I replaced both with Bosch from AutoZone, the downstream one should have tipped me off when they had the wrong part in the right box. I've since put the (I'm assuming) correct ones in their proper places, but am getting confused and annoyed.

My CEL is still on, and I've checked both the OBD2 scanner and the onboard diagnostic (turning the key multiple times to show P codes). OBD2 shows 0032, 0038, and 0038PD, onboard shows 0522, 0032, and 0038. I know 0522 is something to do with the engine oil pressure sensor (it's only done this since my O2 sensors went bad) but I can't figure out why the other codes are coming up.

I've pulled battery power for a few hours hoping to reset the computer, no such luck. I've driven it maybe 60 miles since replacing the second O2 sensor. I've tried to erase the codes using the scanner, no luck there either.

I really don't want to bring it in to the mechanic, since I'm laid off, I figured this was something I could do myself.

Side note, I noticed that if I plug in my block heater my oil light doesn't come on... it also shuts off if I turn it on, notice the light, and immediately shut it back off then restart. There is no known oil leak, and all fluids look good including

People here have reported problems with Bosch O2 sensors. For some reason they don't work well on Chrysler products. Try another brand or a Chrysler OEM part.

Bosch O2 Sensors DO NOT work in Chrysler Products.
