I just took the car in to the dealer because my CEL was coming on and going out every so often. P0131 O2 Sensor Circuit Low Voltage (Bank 1 Sensor 1) (according to the code list on this site) is what was revealed. Do I need a new O2 sensor, new battery or shell out the $200 - $300 to get it looked at and fixed?
