Diagnostic Trouble Code Identification/Availability
The following table lists only those codes available for this engine, as well as their identifications.
The diagnostic trouble code charts are used to find and repair problems which the Diagnostic Circuit Check has found. If the Diagnostic Circuit Check shows that codes have been stored, proceed to the appropriate code chart. If more than one code has been stored, always start code diagnosis with the lowest code number and work upward.
These charts are not contained in this article. They can be found in the appropriate article in the ENGINE PERFORMANCE Section.
