The Check Engine Light can be counted among those unnerving warnings that a car can send to its owner. The light is meant to appear on the dashboard and can either stay illuminated or start blinking. There will be a phrase highlighted, that reads “check engine”. Till that all it could convey is that your car has an issue which is related directly or indirectly to the engine. Many times, this “check engine” light is taken lightly by the car users, if the car continues to drive, but if the car doesn’t move any further while showing up this warning message, then it is really something worrisome, admitted an experienced mechanic of the department of Palmyra check engine light servicing.
He further added that when your car dashboard is displaying the “check engine” light for long, it means, you must take a look at the mechanisms that are working under the hood, by popping it up once. If you do not find anything out of place there, all you can do is call a professional for help.
Loosened Gas Cap:
Do you know that the apparently serious looking check engine light can get turned on just because of a loosened gas cap? This gas cap that seals the engine compartment to protect the fuel and its optimum pressure in the fuel tank, might crack up because of salt deposits or might simply turn loose from its place. But since that will start spilling out the fuel into the compartment, which is dangerous for the vehicle, the check engine light will automatically get turned on to warn you against it.
After fixing back the gas cap issue turns off the check engine light, you are already on the safer side. But if it doesn’t you can try few more tricks, like, replacing the spark plug, change the engine oil, and then try again.
Faulty Oxygen Sensor:
The oxygen sensor plays an important role in vehicles. It is responsible for keeping the exhaust system up and running, by measuring the amount of unburned oxygen. It indicates the efficiency of the engine and if the air-to-fuel ratio is correct. When the oxygen sensor gets out of order, it would not be able to provide the accurate data to the onboard computer.
It is important to know that the damage of the oxygen sensors can happen because of worn-out precious metals that are the major composite items of the oxygen sensor. If you continue to drive your car without replacing the damaged oxygen sensor it can eventually harm the catalytic converter leading to a graver issue that might ask for costlier repairs.
Damaged Catalytic Converter:
The mechanics who conduct CEL testing near Palmyra concluded that the check engine light will certainly get displayed if the catalytic converter of your car engine fails to perform. The catalytic converter is meant to reduce the number of emissions from the exhaust system and is placed there itself. When it gets damaged, the emission starts increasing while decreasing the fuel efficiency of the vehicle.
