C5 Codes

Hey guys constantly getting P0134, 0135, 0154 and 0155 codes. Basically an issue with my O2 sensors. Could an aggressive cam, unburnt fuel and such trip those codes.

Possibly. Could be dead O2s too. Two of the codes are heater codes, and 2 are insufficient activity codes.

Hmm, I never thought of that. Is there a way to bench test them first?

It's easier to just scan them, that'll at least tell you if they're switching.

You can ohm the heaters, but I'm not sure what the resistance should be. Used to know, but that brain space has since been occupied by more important numbers LOL
