Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
•
The vehicle will not pass this inspection if the check
engine light is on with the engine running, or if the
key is in ON/RUN and the light is not on.
•
The vehicle will not pass this inspection if the
OBD II (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 the battery has recently
been replaced or if the battery has run down.
The diagnostic system is designed to evaluate
critical emission control systems during normal
driving. This can take several days of routine
driving. If this has been done and the vehicle still
does not pass the inspection for lack of OBD II
system readiness, your dealer/retailer can prepare
the vehicle for inspection.
Oil Pressure Gage (US-Canada)
For vehicles with an engine oil pressure gage, it shows
the engine oil pressure in psi (pounds per square
inch) when the engine is running. Canadian vehicles
indicate pressure in kPa (kilopascals).
Oil pressure can vary with engine speed, outside
temperature and oil viscosity, but if readings are outside
the normal operating range, the oil pressure light
comes on. See Oil Pressure Light on page 3-49 for
more information.
