TROUBLESHOOTING GUIDE

Most of the fuel and emission control systems are electrically controlled, often making it difficult to diagnose problems, especially intermittent problems. Before undertaking actual checks, take a few minutes to talk with a customer who approaches with a drivability complaint. The customer is often a good source of information on such problems, especially the intermittent ones. Through a talk with the customer, you will usually find out what the symptoms are and under what conditions they occur.

The diagnostic index lists troubleshooting items in a table with the columns: No. (each troubleshooting item is assigned a number), Troubleshooting Item (there are 27 troubleshooting items; choose the item that most closely corresponds to the actual symptom), Description (describes each troubleshooting item), and Page (shows the reference page). See fig2 for the annotated layout.
