Introduction
TROUBLESHOOTING GUIDE
Most of the fuel and emission control system is electrically controlled, often making it difficult to diagnose
problems in the system, 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 intermittent ones. Through talks with the customer, one can find
out what the symptoms are and under what conditions they occur.
