Check Engine light comes on my dash

 

The 'Check Engine' light comes on my dash, what's wrong? Is it safe to drive my

car?

 

Today's vehicles have an onboard engine computer, what we call ECM (Electronic Control

Module) that controls the fuel injection system. The ECM monitors all the engine input sensors 

and make adjustments on air/fuel ratio, ignition timing and emission, etc. When there is a problem 

in your system, the ECM records the problem and stores a trouble code, then it turns the 'Check 

Engine' light on.

Is it safe to drive? It depends on what trouble code is stored in the computer. In worst situation,

driving with check engine light may result in more damage to your vehicle. If your check engine 

light came on or flashing, have the your vehicle inspected as soon as possible.
