Question

2002 Dodge Ram 1500, where is the HO2S bank 2 sensor 1 heater at?

Answer 1

HI there,

The heater is part of the sensor. It has a heating element inside it that works when you first start the vehicle to try and get it into closed loop faster. Usually when you have this code, replacing the sensor will resolve the problem because the heater element inside the sensor has burned out.
