- Turn the ignition off.
- Allow the vehicle to sit with the ignition off in an environment where the temperature is consistent and more than -7 °C (19.4 °F) until the engine coolant temperature is equal to ambient temperature.
- Turn the ignition on.
- Using a thermometer, measure and record the underhood and ambient temperatures.
- With a scan tool, read the ambient air temperature, engine coolant temperature, engine oil temperature, and intake air temperature sensor values, as applicable.
Are all temperature sensor values within 10 °C (18 °F) of the thermometer and the other sensor values?
