Conditions for Setting the DTC
NOTE:
P00E9 Can fail under any of the following 3 sets of conditions.
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 25°C (45°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 (45°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 (45°F).
P00E9-Condition 2
- The ECM determines the IAT sensor 1 start-up temperature is between the IAT sensor 3 and the IAT sensor 2 start-up temperatures
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 (45°F).
AND
- The ECM determines the absolute difference between IAT sensor 3 and the IAT sensor 1 start-up temperatures is greater than the absolute difference between IAT sensor 2 and the IAT sensor 1 start-up temperatures.
P00E9-Condition 3
- The ECM determines the IAT sensor 2 start-up temperature is between the IAT sensor 3 and the IAT sensor 1 start-up temperatures
AND
- The ECM determines the absolute difference between IAT sensor 3 and the IAT sensor 1 start-up temperatures is greater than 25°C (45°F).
AND
- The absolute difference between IAT sensor 3 and the IAT sensor 2 start-up temperatures is greater than the absolute difference between IAT sensor 2 and the IAT sensor 1 start-up temperatures.
DTC P00E9 runs once an ignition cycle when one of the above 3 enabling sets of conditions are met.
