P0096 - INTAKE AIR TEMPERATURE SENSOR 2 CIRCUIT RANGE/PERFORMANCE (BANK 1)
| Description: | This DTC sets when the intake air temperature 2 (IAT2) sensor value does not correlate with the charge air cooler temperature (CACT) sensor value or the intake air temperature (IAT) sensor value at ignition ON after a calibrated soak period (typically 6 to 8 hours). This DTC also sets if the IAT2 sensor value exceeds the maximum calibrated temperature threshold while driving. | ||

| Diagnostic Aids: | The IAT2 sensor is located on top of the intake manifold.

Check for other DTCs and diagnose those first. |
