Diagnostic Trouble Code Definitions

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 DIAGNOSTIC TROUBLE CODE DEFINITIONS  table, diagnose by symptom in TROUBLE SHOOTING - NO CODES 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.

(1) DTCs apply to all models, unless otherwise indicated.
(2) Refer to WIRING DIAGRAMS article to verify model is equipped with cylinder head or engine coolant temperature sensor.
(3) See DIAGNOSIS - 4R44E AUTOMATIC TRANSMISSION or AUTOMATIC TRANSMISSION - DIAGNOSIS - 5R44E & 5R55E .
(4) See TEST A: DTC P0442: SMALL LEAK DETECTED IN EVAP SYSTEM  under SYSTEM TESTS (EVAPORATIVE EMISSIONS).
(5) Flash Vehicle Identification Block needs to be reprogrammed. See FLASH VEHICLE IDENTIFICATION BLOCK PROCEDURE  under PROGRAMMING PCM.
(6) Ensure aftermarket performance products are not being used before replacing PCM. Replace PCM. See PROGRAMMING PCM .
(7) DTC P1000 is ignored in KOEO and KOER ON-DEMAND SELF-TEST. If DTC P1000 is retrieved from continuous memory, go to Test QC  , step  1).
(8) See appropriate CRUISE CONTROL SYSTEMS article in ACCESSORIES & EQUIPMENT for test procedures.
(9) DTC is transfer case related. See appropriate DIAGNOSIS article in TRANSFER CASES for test procedures.
