P00CE - INTAKE AIR TEMPERATURE MEASUREMENT SYSTEM - MULTIPLE SENSOR CORRELATION - DTC CHART

Description: This DTC sets when the charge air cooler temperature (CACT), intake air temperature (IAT) and the intake air temperature 2 (IAT2) PIDs are each greater than 16.67°C (30°F) different from each other at start up or that each sensor is out of the calibrated range at engine start up after a soak period of at least 6 hours when a block heater is not used.
Possible Causes: Damaged CACT, IAT or IAT2 sensors Contaminated or restricted CACT, IAT or IAT2 sensors Slow responding CACT, IAT or IAT2 sensors
Diagnostic Aids: Compare all sensor readings to the ambient temperature to determine which sensor is reading correctly. This DTC may be accompanied by other DTCs. Check for other DTCs and diagnose those first.
