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 it
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.

Light
If you have a low engine
oil pressure problem, this
light will stay on after
you start your engine, or
come on and you will hear
a chime when you are
driving.
This indicates that your engine is not receiving enough
oil. The engine could be low on oil, or could have
some other oil problem. Have it fixed immediately.
When the ignition is on but the engine is not running,
the light will come on as a test to show you it is working,
but the light will go out when the engine is running. If
it doesn’t come on with the ignition
on,
you may have a
problem with the bulb. Have it fixed right away.

if
the oil pressi..

you do, your engine can become
so

catches fire. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.

Damage to your engine from neglected oil
problems can be costly and
