Check engine and VSC lights gone - P0037
So I had a check engine light code was "P0037" Bank 1 Sensor 2 Heater Circuit Low. I thought it was lower O2 sensor on the front cat. Turned out to the Air fuel mixture sensor. Just an FYI if anyone else get this code

didn't know the GS used A/F ratio sensors... I've probably replaced all of my o2 sensors on my 2gs3.. and they were just that.. o2 sensors... the only time I've had to replace an a/f ratio sensor was on my 2000 Solara with calif emiisions..

you guys realize they are essentially the same thing...
they are actually truly both O2 sensors, its just that some are a little more sensitive...
standard O2 sensor range is 0 to 1 volt, wideband O2 sensor (sometimes referred to as an air/fuel ratio sensor) is 0 to 5 volts...
