P0111 - INTAKE AIR TEMPERATURE SENSOR 1 CIRCUIT RANGE/PERFORMANCE (BANK 1)
| For GTDI | |||
| Description: | This DTC sets when the intake air temperature (IAT) sensor value does not correlate with the charge air cooler temperature (CACT) sensor value or the intake air temperature 2 (IAT2) sensor value at ignition ON after a calibrated soak period (typically 6 to 8 hours). If the IAT2 sensor is not present, the engine coolant temperature (ECT) sensor value or the cylinder head temperature (CHT) sensor value is used for the rationality test. This DTC also sets if the IAT sensor value exceeds the maximum calibrated temperature threshold while driving. |
||
| Possible Causes: |
|
||
| Diagnostic Aids: | The IAT sensor is located on the air filter housing. | ||

| Possible Causes: |
|
||
| Diagnostic Aids: | Make sure the IAT reading and the other temperature sensor readings are similar when the engine is cold. | ||
