My car just threw a code, I didn't notice any erratic idle symptoms, no over heating, nothing. I went to Autozone and they said that my 02 sensor heater malfunctioned. Bank 1 Sensor 2. They concluded this because they scanned my car and got the P0141. I searched and found that these cars FALSELY throw the codes? I was wondering now that my 01 Grand am is out of warranty with 60k miles, should I take it to the dealership and tell them to update my cars computer? Or will they charge me? And how can I tell which sensor it is, and or if it's really bad?
