Diagnostic Trouble Code Definitions

NOTE: For DTC descriptions, see Fig 1-Fig 58 .
NOTE: Prior to performing any system test, see HOW TO USE SYSTEM TESTS  under SYSTEM TESTS. If instructed to replace Powertrain Control Module (PCM) after performing a system test, new PCM must be programmed. See PROGRAMMING PCM .

If a DTC appears with an "x" in the numerator (example DTC P071x), "x" denotes any number between 0-9. If a "P" series DTC appears that is not listed in, diagnose by symptom in TROUBLE SHOOTING - NO CODES - CNG, FLEX-FUEL & GASOLINE article for symptom diagnosis. On some models, PCM is capable of storing some body DTCs. If any "B", "C" or "U" series DTCs are retrieved (example DTC B1213, C1702 or U2195), go to appropriate MODULE COMMUNICATIONS NETWORK article in ACCESSORIES & EQUIPMENT to determine test to perform.
