Detecting Condition |
Possible Cause |
| DTC Strategy |
Case 1 |
|
- Poor connector connection
- Short or open circuit
- Faulty humidity sensor
|
| Case 2 |
|
| Enable Conditions |
Case 1 |
- Engine coolant temperature is less than 70°C (158°F)
- When the difference between HFM humidity temperature and Ambient air temperature temperature is above 6°C (42.8°F)
- No HFM chip heating
- No humidity sensor device error
- No SENT protocol error
- Ambient air temperature is between -10 to 50°C (14 to 122°F)
- Engine coolant temperature is between -10 to 60°C (14 to 140°F) at engine start
- The difference between the coolant temperature value and the ambient air temperature sensor value at engine start is less than 10°C (50°F)
- Accumulated crankshaft revolution is less than 100 times
|
| Case 2 |
- No HFM chip heating
- No humidity sensor device error
- No SENT protocol error
- Ambient air temperature is between -10 to 50°C (14 to 122°F)
- Engine coolant temperature is between -10 to 60°C (14 to 140°F) at engine start
- The difference between the coolant temperature value and the ambient air temperature sensor value at engine start is less than 10°C (50°F)
- Accumulated crankshaft revolution is less than 100 times
|
| Threshold Value |
Case 1 |
- If there is an error in maximum humidity plausibility
|
| Case 2 |
- The difference between the maximum relative humidity and the minimum relative humidity is less than 5%
- The difference between the maximum HFM humidity temperature and the minimum HFM humidity temperature is more than 10°C (50°F)
