2000 f53 chassis. P00113 code. voltage too high. The 5.0 volt reference voltage is present at the switch (grey wire) . Grey/red wire is the return and it shows a perfect ground. The switch checked out with the 5 volts to the pin. A little heat and the voltage adjusts accordingly. Switch is good tested by itself. No matter what I do, I get -40 in my live data. I am afraid this means a new PCM. Ouch!! What am I missing?

P0113 IAT voltage too high

Next step is measure voltage at the pin on the PCM.
