Test 3 - 6:

SYMPTOM
P0111 - INTAKE AIR TEMP SENSOR PERFORMANCE

WHEN MONITORED
With the ignition on. Coolant Temperature greater than 71 °C (160 °F) No Inlet Air Temperature Sensor Faults present

SET CONDITION
After 5 warm cycles have occurred (coolant increases from great than 4.4 °C (40 °F) to a minimum of 71 °C (160 °F) and the odometer mileage has increased 196.6 miles and the Inlet Air Temperature has increased less than 3 °C (5.4 °F) change in temperature. Two trip fault.

POSSIBLE CAUSES
- Good trip equal to zero
- IAT sensor voltage below 1.0 Volts
- Resistance in the (K900) sensor ground circuit
- Resistance in the (K21) IAT sensor signal circuit voltage drop
- PCM
