| Main Action |
|
- Poor connection or damaged harness
- Faulty OTS
|
| Case 1 |
Prerequisite Condition |
- Battery voltage is between 6V and 16V
- Difference between highest and lowest modeled oil temperature is between 30°C (86°F) and 100°C (212°F)
- Engine coolant temperature is higher than 82°C (179°F
- Engine coolant temperature at start is lower than 53.25°C (181.85°F)
|
| Threshold value |
Sensor signal stuck in range
- Difference between highest and lowest modeled oil temperature is lower than 2°C (35°F) to 35°C (95°F).
|
| Diagnosis Time |
- Maximum 13 minutes (depends on engine coolant temperature while starting)
|
| Case 2 |
Prerequisite Condition |
- Battery voltage is between 6V and 16V
- Engine coolant temperature at start is higher than 40°C (104°F)
- Modeled oik temperature is higher than 70°C (158°F)
|
| Threshold value |
Sensor signal implausible low
- Engine oil temperature is lower than 20°C (68°F)
|
| Diagnosis Time |
|
| Case 3 |
Prerequisite Condition |
- Battery voltage is between 6V and 16V
- Engine coolant temperature is lower than 70°C (158°F).
|
| Threshold value |
Sensor signal implausible high
- Engine oil temperature is higher than 100°C (212°F).
|
| Diagnosis Time |
|
| Case 4 |
Prerequisite Condition |
- Battery voltage is between 6V and 16V
- Engine stop time is longer than 480 minutes
- Engine coolant temperature is dropped lower than or equal to 1.4°C (34.5°F).
|
| Threshold value |
- Deference between engine oil temperature sensor and 2 other temperature sensors (ECT, AAT, IAT) is higher than 20°C (68°F)
- Defference among other temperature sensors (ECT, AAT, IAT) is lower than or equal to 20°C (68°F).
