DTC DESCRIPTION P00AB - INTAKE AIR TEMPERATURE SENSOR 1 CIRCUIT RANGE/PERFORMANCE (BANK 2)
| Description: | This DTC sets when DTC P0111 is not present and the intake air temperature bank 2, sensor 1 (IAT21) value does not correlate with the intake air temperature bank 1, sensor 1 (IAT11) value at ignition ON after a calibrated soak period (typically 6 to 8 hours). The intake air temperature 2 (IAT2) and charge air cooler temperature (CACT) value is used for the rationality test. This DTC also sets if the IAT21 sensor value exceeds the maximum calibrated temperature threshold while driving at a low load and a speed greater than 56 kMH (35 MPH). |
