When Monitored
WARNING: This page is about a different variant/trim than selected.
This diagnostic runs when the following conditions are met:
- Engine off time is greater than 480 minutes.
- Ambient temperature is greater than -64°C (-83°F).
- Intake air temperature is greater than -64°C (-83°F).
- Engine coolant temperature is greater than -64°C (-83°F).
- Vehicle speed is above 30-35 mph for 30 seconds to one minute depending on calibrated values.
- Once the vehicle is soaked for a calibrated engine off time and then driven over the calibrated speed and load conditions for a calibrated time, the PCM compares the Ambient, Engine Coolant and Intake Air Temperature Sensor values.
