| DTC Strategy |
|
- Poor connector connection
- Air cleaner dirt
- Damage to the engine oil cap or dipstick, not attached or improperly mounted
- Intake system leakage
- Faulty IAT sensor
|
| Enable Condition |
Case 1 |
- Engine speed is between 768 and 960 RPM
- Engine Coolant Temperature (ECT) is greater than 56°C (132.8°F)
- Integrated mass air flow is greater than 9000g
- Battery voltage is between 11V and 16V
|
| Case 3 |
- Battery voltage is between 11V and 16V
- Engine stop time is more than 480 minutes
- After engine start, engine coolant and engine oil temperature decreases below 2.5°C (36.5°F) for 15 seconds over 25 km/h (15.53 MPH) in vehicle speed
- After engine start, the ambient air temperature decreases below 2.0°C (35.6°F) for 15 seconds over 25 km/h (15.53 MPH) in vehicle speed
- After engine start, the intake air temperature decreases below 4.0°C (39.2°F) for 15 seconds over 25 km/h (15.53 MPH) in vehicle speed
- Intake air temperature is above -30°C (-22°F)
|
| Threshold Value |
Case 1 |
- Intake air temperature signal variation since engine start less than 0.15 - 0.26°C (32.27 - 32.47°F) (Depending on intake temperature)
|
| Case 3 |
- Difference between the maximum value of the intake air temperature sensor and the maximum value of the ambient air/engine coolant temperature 1/engine coolant temperature 2/oil temperature is more than 20° C (68°F) and is detected more than 3 times
