I've got this code coming on after the car got hot one day, which explains why it got.
P0480 is what Autozone diagnosed. The PCM has determined that a malfunction exists in the control circuit for cooling fan 1.
P0481: Same thing, except with cooling fan 2.
P0133: The response time for oxygen sensor 1 in bank 1 was too slow during testing. Easy enough to replace and figure out, I believe.
What should/can I do myself about codes 480 and 481?
Thanks!
