The winter is kicking the crap out of my car. I need to get a garage but that's a different issue...Anyway..

P0153 C Heated Oxygen Sensor (HO2S) Slow Response Bank 2 Sensor 1
P1416 H C Secondary Air Injection (AIR) System Bank 2
B0432 H Rear Defogger Relay Circuit
B0332 H Outside Air Temp Sensor Short to GND
B0337 H Inside Air Temp Sensor Short to GND

I reset my codes this morning before my drive to work, and then checked them when I arrived. The codes listed above are the ones I received. I didn’t get any “check” lights at all.
The P1416 code I got before and I’m working on getting the parts for the air check valve. All the others are new. Does this look list a grounding issue or should I check each thing? The defroster and heater worked just fine on my way to work this morning. I’ll clear the codes before my trip home and then look again to see what’s up.

The only thing I did this weekend to my car was jack it up and clean the wheel speed sensors and wash it.

I want to confirm....you cleared all codes before work then checked the ECM memory when you got to work and all five of those reset?? If yes, then you've got "hard" codes. I'm not close to my service data right now but those codes may not set a light when they occur. Are they showing up as current or history.

For sure I'd check gronding to see if the 0153 goes away. If it doesn't change the sensor. Two of them indicate shorts to grounds with two different hvac sensors, so they might not be a grounding issue.

I'd suggest, getting out the service manual and using the data in it for each of those codes to troubleshoot those systems.
