The resistance value of temperature sensor may test good at certain temperature but it might be defective at other temperaturesIf in doubt, try new sensorAlso remember this validates the operation of the sensor at room temperatureIt does not validate the over temperature functionalityTo test it, the sensor could be removed from the engineair silencer and heated with heat gun while it is still connected to the harness to see if the ECM will detect the high temperature condition and generate fault code
