Diagnostic Trouble Code Identification/Availability
NOTE:
The 1.6L "Minimum Function" system does not store codes. They are erased at key OFF.
The following table lists only those codes available for this engine, as well as their identifications.
The fault 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.
