What size resister to fake O2 heater?
Okay so I have two O2 sensors... both O2 portions function fine but the heater's are blown out.
What size resister could i use just to connect the two black wires so the ecu thinks the heater is working?

Should be between 15 to 40 ohms. For power you can conservatively use 15volts... (V^2/R)
So at 15 ohms you need a 15 watt (or higher) resistor.
At 25 ohms you need a 9 watt (or higher) resistor.
At 40 ohms you need a 6 watt resistor.
