what engine, what size. that is first question.
misfire, map ,maf, iat, ect,tps and cat fail and low coolant temps.

the question is , which is the most important.
all are cept 420, (last that, and bet goes way. later.)

reset the ECU, and see which come back.?
check all fuses.
then post codes that repeat, after fuse checks.

does the engine get fully hot running, 180F minimum?

Forget to write it down?

Generic or Manufacturer?

There are 41 Generic O2 Codes

PO 131--bank 1 sensor 1
PO 137--bank1 sensor 2
PO 143--bank1 sensor 3
PO 151--bank2 sensor 1
PO 157--bank1 sensor2
PO 163--bank2 sensor 3

I would check the computer for codes first. The cooling fan comes on at 220 degrees so if your gauge is right it should not need the fan yet.
