A Artur1976 Member Contributor : 2003.7 mazdaSpeed Protege Jan 11, 2009 #1 I am getting this code P0037 HO2S Heater Control Circuit Low Bank 1 Sensor 2. I just put on a brand new O2 sensor. What else could be the problem?

S slavrenz Member : 2001 Mazda Protege LX 2.0 Jan 12, 2009 #2 Make sure you replaced the right sensor. P0037 is for the rear sensor, not the front. If that's the one you replaced, then you've either got some bad wiring around the sensor or your computer, or you've got a bad computer.
