Hey all, New to the site, but I'm benefited from these threads far before this. Thanks for all the help up to this point. Got a carwash with an undercarriage spray on the way to work this morning. Shortly after a check engine light came on, so I pulled over and read codes C1214 and P0138. I finished driving to work and the car operated normally. I did not observe any change to braking or the engine. Curious if anyone has had experience with a car wash tripping codes? When I get out of work, I plan to do a quick inspection of the downstream 02 sensor and the brake lines to see if I can spot anything out of the ordinary.
