P0172-System too rich (bank1)
P2231- 02 sensor issue
P0455- Evap. system leak.
In this video I show the location of the O2 sensor and the purge valve. These are the most common issues when these code show up on your car.
I made this video in an attempt to further assist people with like issues. I learn as I go in the mechanic field and thought I would attempt to help other DIY people in the process. Hope you enjoy and comment with any questions or issues.
