P0037 H02S Heater Control Circuit Low (Bank 1 Sensor 2)
My 'service engine soon' light has started coming on for a day or so, then it goes off for a day or so, and repeats. There is No 'Increased Emissions' message though. I checked the code, and it reads:
P0037 H02S Heater Control Circuit Low (Bank 1 Sensor 2) I had both Post Catalytic Oxygen Sensors replaced last year. Does anyone have an idea what might cause this? |
