Detecting Condition & Fail Safe |
Possible Cause |
| Case 1 |
DTC Strategy |
|
- Poor connection or damaged harness
- Faulty ECT sensor
- Faulty cooling system
|
| Enable Conditions |
- Battery voltage is between 6 V and 16 V
- Coolant temperature at Start lower than 76°C (169°F)
|
| Threshold Value |
- When water Temperature is not changed comparing with it at the time of engine start
|
| Case 2 |
DTC Strategy |
|
| Enable Conditions |
- Battery voltage is between 6 V and 16 V
- Coolant temperature at Start lower than 76°C (169°F)
- IAT at engine start between -10°C (14°F) and 70°C (158°F)
- Part Load driving condition (Engine speed higher than 1400 RPM, Vehicle speed faster than 22km/h (13.6mph), Mass air flow greater than 5.5 g/sec)
- Low Load driving condition (Fuel Cut Of or Idle with vehicle speed slower than 19.3km/h (12mph)
- Ambient temperature is higher than -10°C (14°F)
|
| Threshold Value |
- ECT variation since engine start lower than 2.25°C (36.05° F)
|
| Case 3 |
DTC Strategy |
|
| Enable Conditions |
- Engine Coolant Temperature (ECT), Intake Air Temperature (IAT), Engine Oil Temperature (EOT) drop is lower than 2° C (35.6°F) within 15 sec. right after engine starts
- Engine Stop time longer than 480 sec.
|
| Threshold Value |
- Deviation between ECT and 2 other temp. sensors (IAT, AAT or EOT) higher than 20°C (68°F) and Deviation among other temp. sensors (IAT, AAT, EOT) lower than 20° C (68°F)
