The Check Engine or SES light is one of the most common warnings
to come on the dash of todays cars and trucks.
This indicates the Powertrain Control Module (PCM or ECM) is seeing
a problem in the emissions control system. A simple scan tool is all
that is needed to read the stored trouble codes that the computer has
in its memory. These codes give an indication as to what system is
having a problem. Many of the large national parts store chains will
also do this for free.
If the light is flashing, you need to have the car or truck checked by a
mechanic as soon as possible. This is because a flashing SES means
that the engine is misfiring bad enough to cause catalytic converter
damage. This can be very expensive to replace.
