| Case 1 |
DTC Strategy |
- Sensor signal stuck in range
|
- Poor connecting condition
- Faulty OTS
|
| Enable Condition |
- Difference between highest and lowest modeled oil Temp is higher than 30 to 100°C (86 to 212°F)
- Engine coolant Temp. is higher than 90°C (194°F)
- Engine coolant Temp. is higher than 90°C (194°F)
- Battery voltage between 11V and 16V
|
| Threshold Value |
- Difference between highest and lowest modeled oil Temp. is lower than 2 to 35°C (35.6 to 95°F)
- Sensor signal is stuck in range
|
| Diagnostic Time |
- 0 to 13 min. (depending on start temp.)
|
| Case 2 |
DTC Strategy |
- Sensor signal implausible low
|
| Enable Condition |
- Battery voltage between 6V and 16V
- Coolant Temp. (at start) is lower than 40°C (104°F)
- Modeled oil temperature is higher than 70°C (158°F)
|
| Threshold Value |
- Engine oil temperature (EOT) is lower than 20°C (68°F)
- Sensor signal is implausibly low
|
| Diagnostic Time |
|
| Case 3 |
DTC Strategy |
- Sensor signal implausible high
|
| Enable Condition |
- Coolant Temperature is lower than 70°C (158°F)
- Battery voltage between 6V and 16V
|
| Threshold Value |
- Measured oil Temp is higher than 100°C (212°F)
- Sensor signal is implausibly high
|
| Diagnostic Time |
|
| Case 4 |
DTC Strategy |
- Comparing with other temperatures (ECT, IAT, AAT) at start after long engine stop time
|
| Enable Condition |
- Battery voltage between 11V and 16V
- Engine stop time is longer than 480 minutes
- ECT decrease in 15s after engine start is less than 2°C (35.6°F)
|
| Threshold Value |
- Deviation between EOT and 2 other temp sensors (ECT, AAT, IAT) is higher than 20°C (68°F) when deviation among other temp sensors (ECT, AAT, IAT) is lower than 20°C (68°F)
