Diagnostic Trouble Codes (DTCs)
This section contains the J2012 Diagnostic Trouble Codes
(DTCs) as defined by the Society of Automotive Engineers (SAE).
Diagnostic Trouble Codes (DTCs) are recommendations not a
requirement. Manufacturers may not follow these, but most do.
Check vehicle’s service manual for DTC meaning if the code(s)
you are getting does not make sense.
Diagnostic Trouble Code (DTCs) definitions have been assigned
or reserved by the Society of Automotive Engineers (SAE) to
direct to proper service area(s).
Codes not assigned or reserved by the Society of Automotive
Engineers (SAE) are reserved for the manufacturer and referred
to as Manufacturer Specific Diagnostic Trouble Codes (DTCs).
Remember:
• Visual inspections are important!
• Problems with wiring and connectors are common,
especially for intermittent faults.
• Mechanical problems (vacuum leaks, binding or
sticking linkages, etc.) can make a good sensor look
bad to the computer.
• Incorrect information from a sensor may cause the
computer to control the engine in the wrong way. Faulty
engine operation might even make the computer show
a known good sensor as being bad!
NOTE: Additional DTC definitions can be obtained from the CD
supplied. If there are any problems operating the
