Hi Guys

So I have the following SES codes and I'm wondering what the impact is of not fixing them (I don't need to pass any inspection here). I know my mileage might be impacted. Any other major issue in not fixing the codes?

Current codes are:

[P0135] HO2S1 HTR (B1)
[P0141] HO2S2 HTR (B1)
[P0443] PURG VOLUME CONT/V

 

They will impact ur fuel milage

 

Your EVAP code won't matter too much, but with one upstream O2 dead/dying, your gas mileage may likely take a dive, as watut said.
