Does anyone with a 2004 Maxima have an OBD2 scan-tool that would be willing to pull some sensor values and post them? My Bank 1 Sensor 1 and Bank 2 Sensor 1 O2/Air Fuel Ratio Sensors have mismatched voltages which doesn't make sense. Thinking I had a bad sensor I replaced both Air Fuel Sensors in both banks and the voltage values remained mismatched. Here are the values I am interested in, warm engine at idle and warm engine at 2000 rpm:

SAE 0x14 Oxygen Sensor Voltage Bank 1 Sensor 1. My value= .3V
SAE 0x15 Oxygen Sensor Voltage Bank 1 Sensor 2. My value= .3V
SAE 0x18 Oxygen Sensor Voltage Bank 2 Sensor 1. My value= .61V
SAE 0x19 Oxygen Sensor Voltage Bank 2 Sensor 2. My value= .3V

Thanks in advance for you time.

 

I had a problem with O2 sensor bank 2 .
I have replaced my engine and SES light came . checke by revUP tuner and said I have O2 sensor bank 2 but which on ? I dont know .

I didnt replace it for 3 years but the car still runing good
