Symptom List:
P0110-INTAKE AIR TEMPERATURE SENSOR STUCK
P0111-INTAKE AIR TEMPERATURE SENSOR PERFORMANCE
Test Note: All symptoms listed above are diagnosed using the same tests.
The title for the tests will be P0110-INTAKE AIR TEMPERA-
TURE SENSOR STUCK.
When Monitored and Set Condition:
P0110-INTAKE AIR TEMPERATURE SENSOR STUCK
When Monitored: Engine Running.
Set Condition: After 4 warm-up cycles, the PCM did not see a 2°C (6°F) change in the IAT
Sensor voltage within 200 miles . Two Trip Fault
P0111-INTAKE AIR TEMPERATURE SENSOR PERFORMANCE
When Monitored: Engine off time is greater than 480 minutes. Ambient temperature is
greater than -23°C (-10°F).
Set Condition: After a calibrated amount of cool down time, the PCM compares the ECT
Sensor, IAT Sensor and the Ambient Air Temperature Sensor values. If the IAT Sensor
value is not within calibrated temperature amount of the other two temperature sensors
an error is detected. Two Trip Fault.
