I have both of these codes saying that they are at -40 degrees. I know these run on the same circuit to the pcm, but can't figure out where the error is coming from, both sensors test fine and have been swapped and the PCM has been swapped with the same results. I get readings with the key on engine off of 12 volts and the other wire 7 volts treating them like a ground. I am getting frustrated, any ideas? BTW car runs awesome even with both of these codes, but of course no cooling fan.
