In this episode of the Bumper to Bumper Podcast, hosts Dave Riccio, Co-Creator of Bumper to Bumper radio and Jon Riggle dive deep into one of the most misunderstood components in your car: the oxygen sensor (O2 sensor).

If your check engine light’s ever come on and the parts store told you it’s “just an O2 sensor,” you’ll want to hear this. The guys break down:

- What an O2 sensor actually does (and doesn’t do)

- The difference between O2 sensors and air-fuel ratio sensors

- Why replacing one might not fix your check engine light

- What "lean codes" (P0171, P0174) actually mean

- How false O2 sensor diagnosis cost drivers money

Get a clearer understanding of your car's emissions system, and why a simple parts scan at the auto parts store might be giving you the wrong idea. With real-world examples and expert insight, this episode will help you make smarter decisions when you're hit with an O2 sensor code.
