"Bank 1, Sensor 1" Code. Which O2 Sensor? - 5/13/2008 1:32:45 PM    fivehundo   Posts: 58 Joined: 3/7/2008 From: Jackson, CA Status: offline Okay, So after replacing my clutch, and my diff I've got a check engine light on...   (when it rains, it pours) Ran the code and it says "Bank 1, sensor 1 O2 sensor". It's a 4.7L 4x4 2003 extended cab. Which one is that? Is that like the driver's side front or the passenger side front or what? Thanks for the help... _____________________________ "95 is the route you were on, it was NOT the speed limit sign." - Georgia State Policeman Post #: 1
