SYMPTOM
P0111-INTAKE AIR TEMP SENSOR PERFORMANCE

WHEN MONITORED
With the ignition on and no Intake Air Temperature Sensor open/shorted faults present.

SET CONDITION
After 5 warm cycles have occurred (coolant increases at least 22 °C (40 °F) to a minimum of 71 °C (160 °F) and the odometer mileage has increased 196.6 miles and the Intake Air Temperature has had less than 5 °C (9 °F) change in temperature.

POSSIBLE CAUSES
- Good trip equal to zero
- IAT sensor
- Resistance in the (K21) IAT sensor signal circuit
- Resistance in the (K4) sensor ground circuit
- PCM
