P1131 OBD II code
Hello,
I just purchased an 1997 Explorer with 70,000 miles and after a week i got a P1131 code. If someone could please tell me what this code is for i would appreciate it very much. I looked up the codes on line and found that it says "Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank 1"...does this mean i have a bad Oxyegen Sensor??? , and which bank is #1
