Onboard Diagnostic System (Obd Ii) - Dodge 2004 Intrepid Owner's Manual

ONBOARD DIAGNOSTIC SYSTEM (OBD II)

To meet new government regulations and promote
cleaner air, your vehicle is equipped with a sophisticated
onboard diagnostic system called OBD II. This system
monitors the performance of the emissions, engine, and
automatic transaxle control systems. When these systems
are operating properly, your vehicle will provide excel-
lent performance and fuel economy, as well as engine
emissions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator or Service Engine
Soon Light. It will also store diagnostic codes and other
information to assist your service technician in making
repairs. Although your vehicle will usually be driveable
and not need towing, see your dealer for service as soon
as possible.
MAINTAINING YOUR VEHICLE 169
CAUTION!
Prolonged driving with the light on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any state emissions
tests can be performed.
If the light is flashing, severe catalytic converter damage
and power loss will soon occur. Immediate service is
required.
If the gas cap is not tightened properly, the light may
come on. Be sure the gas cap is tightened every time you
add fuel. Tighten the cap until you hear it "click."
