DTC Information: DTC Detecting Condition

Item		Detecting Condition	Possible Cause
DTC Strategy	Case1, 2	Engine speed is below the target while ISC torque is at the maximum during catalyst heating phase	Intake air restriction Exhaust restriction Engine mechanical concern Damaged or sludgy throttle body Vacuum leaks Damaged ECM
DTC Strategy	Case3	Fuel cut-off during stand-still, idle condition and catalyst heating phase
Enable Conditions		Vehicle speed is same as 0 km/h (0 mph) Accelerator pedal is 0% After catalyst heating is greater than 0s Catalyst heating is active Remark: (Catalyst heating condition) ECT at start is between -12 and 42°C (50 and 107.6°F) IAT is greater than -12°C (50°F) BARO is greater than 75.4 kPa (Accelerator pedal) % value of APS1 value, if APS1 has a fault, APS2 is used instead
Threshold Value	Case1	Difference between target engine speed and actual engine speed is greater than 100 RPM Difference between maximum idle torque and actual idle torque is less than 10Nm
	Case2	Difference between actual engine speed and target engine speed is greater than 200 RPM Difference between actual idle torque and min. idle torque is less than 20Nm
	Case3	Greater than 3 times
Diagnostic Time		12s (Once per driving cycle)
MIL ON Condition		2 driving cycles
