Typical Malfunction Thresholds
| Absolute value (Intake air temperature at 21 seconds after engine start - Engine coolant temperature at engine start) | Higher than 12 to 22°C (21.6 to 39.6°F)] (varies with ambient air temperature) |
| Absolute value (Intake air temperature at 21 seconds after engine start - Ambient air temperature at 21 seconds after engine start) | Higher than 20 to 32°C (36.0 to 57.6°F)] (varies with ambient air temperature) |
