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 (P1192 and P1193)

SET CONDITION
After 5 warm cycles have occurred (coolant increases from greater 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). Two trip fault.


POSSIBLE CAUSES
- Good trip equal to zero
- IAT sensor voltage below 1.0 volt
- High resistance in the (K4) sensor ground circuit
- High resistance in the (K21) IAT sensor signal circuit
- PCM
