Symptom Charts Article

WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2004 Mercury Sable, 2004 Mercury Mountaineer, 2004 Mercury Monterey, 2004 Mercury Marauder, and 2004 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.

All diagnosis begins in the SYMPTOM CHARTS article with QT: Step 1: PCM Quick Test. If the PCM Quick Test is completed and no DTCs are received, the technician may be directed to Step 2: No DTCs Present Symptom Chart Index (refer to SYMPTOM CHARTS - CNG, FLEX-FUEL & GASOLINE for details). The No DTCs Present Symptom Chart Index contains the list of symptoms addressed in this article, and will send the technician to the appropriate Step 3: No DTCs Present Symptom Chart. If no PCM DTCs are present and the vehicle symptom is not listed in the Step 2: No DTCs Present Symptom Chart Index, the technician should go the appropriate article to continue diagnosis.
