Verify the following scan tool parameters are within 25°C (45°F) of each other.
- Start-Up IAT Sensor 1
- Start-Up IAT Sensor 2
- If not within 25°C (45°F)
  Refer to Circuit/System Testing.
- Go to next step: If within 25°C (45°F)
Engine running.
Verify the following scan tool parameters are between: -38 and +149°C (-36 and +300°F).
- IAT Sensor 1
- IAT Sensor 2
- If not between: -38 and +149°C (-36 and +300°F)
  Refer to Circuit/System Testing.
- Go to next step: If between: -38 and +149°C (-36 and +300°F)
Operate the vehicle within the conditions for running the DTC. You may also operate the vehicle within the conditions that you observed from the freeze frame/failure records data.
