Diagnostic Trouble Code (DTC) Information ECM-P02A068

Condition 

The Engine control module (ECM) continually monitors the engine's exhaust gases from the oxygen content in the exhaust gases (the lambda value).

Using the built-in functions, the control module can determine the lambda value for each cylinder individually.

The diagnostic trouble code (DTC) is stored if the control module detects that:

• The Engine control module (ECM) detects that the deviation in the lambda value between the cylinders in bank 2 (cyl. 4-6) is too great to compensate using individual fuel trim.

The control module's test for the diagnostic trouble code (DTC) starts in the event of:

• Individual cylinder fuel trim active.

Substitute Value 

• Individual cylinder fuel trim is deactivated.

Possible Source 

• Mechanical fault causes in the engine.

Fault symptom[s] 

• None.
