|P011E – Engine Coolant Temperature 1/Ambient Air Temperature Correlation|
|Description: The DTC indicates that the engine coolant temperature (ECT) and ambient air temperature (AAT) sensor readings differ by more than a calibrated value.
Possible Causes: • Biased ECT or AAT sensor
• Damaged ECT or AAT sensor
• Damaged IAT sensor
Diagnostic Aids: Make sure the ECT, AAT and intake air temperature (IAT) sensor readings are within 18°C (32.4°F) of each other after 6 to 8 hours at a stabilized ambient temperature and the vehicle has not been in direct sun light.
