Check Engine Light - What it means CARS Complete Auto Repair Service

Check Engine Light -
 What the light means and what to do if it comes on.

What The Light Means
      1) Onboard Diagnostics (OBD)
          A)  This controls and monitors your vehicle performance - such as engine speed,  (RPM)
                 fuel mixture, ignition timing. The computer also tells the automatic transmission when to shift.
          B)  When the computer finds a problem it can't correct, it turns on a light that is labeled

                 "engine, or Service engine"        

        C)  When the light come on the computer has stored a "trouble code" in its memory that

                that identifies the source of the problem. (such as - malfunctioning sensor or a
               misfiring engine.
          D)   This is then read with an electronic scan tool or a Diagnostic computer.

What to do
If the 'check engine" light comes on it will either blink or remain constant, depending on the problem.  But it means it is time to get your car/truck checked.

      1)   In late - model cars it usually indicates a misfire that can be burning up your fuel dumping it into your exhaust system.( Have car or truck looked at a.s.a.p.)
                 *This can quickly damage your catalytic converter- requiring expensive repair.
     2) If the light is steady - Just schedule and appointment  - not usually an emergency.
Today's automotive computers often try to compensate when there's a problem; so you may not notice deterioration in performance, even though your fuel mileage is suffering and your vehicle is emitting levels of hydrocarbons & pollutants.
Tips if you Check Engine Light Comes On   
     1) Check your dashboard lights / gauges for 
           A)     Low oil pressure
           B)     Overheating
                      These conditions mean you should pull over and shut off the engine a.s.a.p. in a safe
                      place.
                             On most cars - Yellow "check engine" means investigate - giving you time to
                             investigate and schedule an appointment.
          C)     Try tightening your gas cap. ( keep in mind, it may take several trips before the light
                    resets.
          D)     Reduce speed and load.  If  the 'check engine" light is blinking or you notice any serious
                         *Performance problems, such as a loss of power, reduced speed.  Reduce your speed & try to reduce the load ( if your towing a trailer) on the engine.  ( make an appointment  to have code read)
        
The best advice is to read your owner's manual beforehand and learn the purpose of the "check engine" light and every other gauge and warning indicator on your dashboard.
