Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to: Diagnostic Methods .

In most circumstances, the PCM sets a DTC to help guide diagnostics. Refer to DTC Charts  before using the Symptom Chart. The Symptom column lists the vehicle condition. The Possible Sources column lists a detailed vehicle condition. The Action column lists the action to be performed to determine the cause of the condition. Each action lists the components that can cause the symptom and the individual components in that system.
