DIAGNOSTIC TROUBLE CODES

Print

Following is a listing of the Diagnostic Trouble Code Charts for the various engine control systems covered in this manual. When using these charts along with the ECU self-diagnostic system, remember that a code only points to a faulty circuit not necessary to a faulty component. Loose, damaged or corroded connections may contribute to a fault code on a circuit when the sensor or component is operating properly. Be sure that the components are faulty before replacing them, especially the expensive ones.
