Rough Idle #1
|
Detection Condition (Rough Idle)
-
Prerequisite Conditions: The engine is idling with the vehicle is stopped and the accelerator pedal is fully released
-
Detection Conditions: It is judged that combustion is unstable due to the instantaneous change in engine speed for each cylinder
-
Duration: Depending on the combustion status, between 2 and 10 seconds
|

|
Flow chart [Rough Idling] step 3
|
|
Idling is rough due to unstable combustion in the No. 1 cylinder
|
X0822
|
Rough Idle #2
|
Idling is rough due to unstable combustion in the No. 2 cylinder
|

|
Rough Idle (Plural Cylinders)
|
Idling is rough due to multiple cylinders
As more than one cylinder is affected, the EGR system, fuel system, etc. is suspected

X082E
|
Rough Idle (Low Frequency)
|
Slight rough idle symptoms are detected 3 times in 10 trips
HINT:
As the rough idle symptoms are slight, if rough idle codes other than rough idle (low frequency) code X082E are stored, this code will not be stored.
