Conditions for Setting the DTC

P00E9-Condition 1

• The ECM determines the absolute difference between IAT Sensor 1 start-up temperature and the IAT Sensor 2 start-up temperature is less or equal to 30°C (54°F).

  AND 

• The ECM determines the absolute difference between IAT Sensor 3 start-up temperature and the IAT Sensor 1 start-up temperature is greater than 25°C (77°F).

  AND 

• The ECM determines the absolute difference between IAT Sensor 3 start-up temperature and the IAT Sensor 2 start-up temperature is greater than 25°C (77°F).

P00E9-Condition 2

• The ECM determines the IAT Sensor 1 start-up temperature is between the IAT Sensor 3 start-up temperature and the IAT Sensor 2 start-up temperature

  AND 

• The ECM determines the absolute difference between IAT Sensor 3 start-up temperature and the IAT Sensor 2 start-up temperature is greater than 25°C (77°F).

  AND 

• The absolute difference between IAT Sensor 3 start-up temperature and the IAT Sensor 1 start-up temperature is greater than the absolute difference between IAT Sensor 2 start-up temperature and the IAT Sensor 1 start-up temperature.

P00E9-Condition 3

• The ECM determines the IAT Sensor 2 start-up temperature is between the IAT Sensor 3 start-up temperature and the IAT Sensor 1 start-up temperature

  AND 

• The ECM determines the absolute difference between IAT Sensor 3 start-up temperature and the IAT Sensor 1 start-up temperature is greater than 25°C (77°F).

  AND 

• The absolute difference between IAT Sensor 3 start-up temperature and the IAT Sensor 2 start-up temperature is greater than the absolute difference between IAT Sensor 2 start-up temperature and the IAT Sensor 1 start-up temperature.
