Had a few codes pointing to rear O2 sensors being bad. So i replaced them with new (cheap ones i know) cleared the codes. Drove around for 10 mins now im getting 2 codes 0141 0161 heater open fault something. So i reset the codes again and would not pop one until i rested the truck and restarted. Was thinking of putting a resistor between the heater power in to fool the computer. I dont live in a emissions state. The fuel mileage is still horrible about 110 miles to the tank dont know if that matters.

I tried cheap O2 sensors. They simply do not work. Save your time and money and get some OE Bosch sensors.

The last cheap sensor I bought was wired wrong. The signal wire was switched with the ground. I just spliced and switched and all is well.
