Hi,

Pulled the sensor and just for kicks, I measured resistance across the two poles. Got a reading (forgot what it was) though.

Is there a specific resistance reading for this part? Or perhaps another measurement. I measured the voltage at the IATS plug and got a reading there too. I think anout 4 volts.

Reinstalled sensor after cleaning it off and I still get a 81.36% reading at pin 3 -- X11 connector.

Any thoughts?
