Check Engine Light
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable levels
for the life of the vehicle, helping to produce a
cleaner environment. The check engine light comes
on to indicate that there is a problem and service
is required. Malfunctions often will be indicated
by the system before any problem is apparent.

and emission
control systems.
