PO141 code 850 1997

Actually it is a rear O2 sensor heater circuit malfunction code. I do not know what the resistance is for that heater circuit but I bet it is the same as the front one. You could probably check the resistance on the front one and compare it to the rear. Chances are it is dead in the water.
