Symptom Chart
Diagnostics in this service information assumes a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to
DIAGNOSTIC METHODS
for information about these practices.
In most circumstances, the PCM sets DTCs
to help guide with diagnostics. Refer to the DTC CHART before using the symptom chart. The Condition 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 system and the individual components in that system.
