I Need help with my 2006 impala 3.5 motor. Codes bank 1 sensor 1 and bank 1 sen2

Hello, this is a Q&A forum online - no one can contact you via text. You don't need to know where the sensors are, necessarily, except to perhaps check for proper connection and no physical damage. What is necessary is obtaining a diagnostic tool (or enlisting the help of a trained technician that has one) and performing necessary testing that happens as a result of the codes being set. This testing will determine if you have a circuit problem, sensor issues or some kind of other underlying concern that is only showing by setting those codes. Codes do not say the sensors are faulty! Sure, they coincidentally may be, but I'd look elsewhere via proper testing first. www.repairpal.com/repair-shops
