Do You Know What Your Check Engine Light Is Trying To Tell You?

103 55
Do those lights on your vehicle's dashboard drive you nuts when they start flashing at you? Nearly every vehicle has them and they are there for good reasons.
What do they indicate and what should you do if the check engine light comes on? In the following paragraphs, you will see the course of action you should take if you encounter this problem.
The check engine light monitors several systems in your auto.
This pesky light is there for good reasons.
If it is flashing on and off it indicates a larger problem than if it is steadily lit.
In either case, you should consult your mechanic as soon as possible.
Auto repair shops have diagnostic machines that can pin point the exact problem in your engine.
There is a cost when they use them but it is worth it.
However, there are some immediate things you can check on your own.
First check your coolant level.
An over heated engine is very dangerous for your car.
You should stop immediately and add coolant to prevent the engine's block from cracking.
If this happens it could cost you thousands of dollars to repair.
Another thing you can check is if your gas cap is securely in place.
Some engine lights can be faulty but you shouldn't risk not having yours checked out.
Many people tend to ignore the light thinking it will eventually go out on its own.
However, there can be a problem with the engine control unit, the on board diagnostic system or the emissions system.
These things monitor several systems in your engine and if something is wrong with one of these systems your check engine light will come on.
Some of the items that could be wrong with your auto are as follows:
  • A wet engine
  • A blown head gasket
  • Faulty oxygen sensors
  • Worn out spark plugs or wires
  • Loose or cracked hoses and manifolds
  • Sticky exhaust gas recirculation valves
  • Pinched or deteriorated fuel injector O-rings
The check engine light is your friend and not a pesky nuisance.
It is there to help you take good care of your vehicle.
When it lights up there are some quick checks you can do on your own, but if your efforts don't fix the problem then a trip to the mechanic is necessary.
This visit may cost you but it is well worth the money to protect the investment you have in your automobile.
