Need help with a code?

[FRESCOLIO]

Sup Fallas? Its been a while. Been busy. I diagnosed a check engine light on my app and found 2 codes. One is Po455 the other is P0455 mod$10. I know they are both evap emision control system leak codes but what part that needs replacing I don't. Im guessing its the converter or o2 sensors thats casuing the light to be on, but I'm not sure. I got a emmission test in the mai;l so maybe I could take it in and gett some info on the exact part needing replacement. Any help will be appreciated.:th_sick2:

Front O2 sensor is bad. Stay away from the Bosch one when you replace it

Napa has NGK or Denso. Any thoughts on them? What is a good brand to put back in?

Denso one...hands down.

P0455 - Evaporative Emission Control System Leak Detected (no purge flow or large leak)

This relates to an o2 sensor how?

This could be something as simple as you started your car with the gas cap off or didn't tighten it down all the way when you were fueling last. It could also be the seal on the cap is bad or... It could be a large crack or hole in the fuel tank/evap system
