Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have or may
begin programs to inspect the emission control equipment
on your vehicle. Failure to pass this inspection could
prevent you from getting a vehicle registration.
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
SERVICE ENGINE SOON light is on or not
working properly.
Your vehicle will not pass this inspection if the
OBD (on
-
board diagnostic) system determines that
critical emission control systems have not been
completely diagnosed by the system. The vehicle would
be considered not ready for inspection. This can happen
if you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still does
not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center to
prepare the vehicle for inspection.
Oil Pressure Light
This light tells you if there
could be a problem with
your vehicle’s engine
oil pressure.
The oil pressure light can come on briefly when you
turn your key to RUN. It goes off once you turn the key
to START. That’s just a check to be sure the light works.
This is normal and doesn’t show a problem. If it doesn’t
come on and then go off, be sure to have it fixed so it
will be there to warn you if there is a problem.
When this light comes on and stays on, and a chime
sounds, it means oil isn’t going through the engine
properly. The oil could be low, or there might be some
other oil problem. See your dealer for service.
