DTC Information: DTC Detecting Condition

Item Detecting Condition Possible cause
DTC Strategy
  • Monitoring deviation between target idle speed and actual engine speed during catalyst heating
  • Restriction in intake or exhaust system
  • Air leakage
  • Checking operation of ETC
Enable Conditions
  • Catalyst heating (ECT at engine start is between -10°C (14°F) and 43° C (109.4°F))
  • Time after start is loger than 9s
  • Vehicle speed is slower than 56.32km/h (35 Mph)
  • Gas Pedal value is less than 0.01%(Pedal is not pushed at all)
Threshold Value
  • Current RPM is lower than target RPM as much as 270 RPM (Engine speed is too low) and idle torque controller is equal to 40 N.m during 5s
  • Current RPM is higher than target RPM as much as 500 RPM (Engine speed too high) and idle torque controller is equal to -20 N.m during 5s
Diagnostic Time
  • 5s
MIL ON Condition
  • 2 driving cycles
