DTC Information And Inspection: DTC Detecting Condition

Item Detecting Condition Possible Cause
DTC Strategy
  • Monitor the engine coolant temperature #2
  1. Poor connector connection
  2. Faulty cooling system
  3. Faulty ECT sensor #2 circuit
  4. Faulty ECT sensor #2
Enable Condition
  • Battery voltage is between 11V and 16V
  • Engine stop time is more than 360 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
  • The activated temperature sensor is above -30°C (-22°F)
Threshold Value
  • Difference between the maximum value of the engine coolant temperature 2 sensor and the maximum value of the ambient air/intake air/engine coolant temperature 1/oil temperature is more than 20°C (68°F) and is detected more than 3 times
Diagnostic Time
  • 0.4 seconds
MIL ON Condition
  • 2 driving cycles
