[QUOTE="Robert Howell, post: 1034471, member: 70748"] Check to heater wire for voltage, also plug one in at a time and look for voltage drop. I don't know the circuit off-hand but if you get the same fault across two sensors at the same time I suspect they are parallel wired off of the same circuit. A short in one can cause an over current to be read by the ECU. Piece of mind - nice avatar! [/QUOTE]
