Question We have two trouble code service engine light on


We have 2001 Saturn SL2 with 220k miles.

I have two trouble codes P0037 and P0410

I believe p0037 means replace downstream oxygen sensor(after cat)

and p0410 means something about air pump correct?

How should I start trouble shooting please advice.
