Cel problem P0037

[Artur1976]

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?

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.

I just got this code today, after installing an AEM wideband.
