Why Check Engine Light Blinks

Let’s know more about the reasons that lead to check
engine light blinking.

It measures the air fuel ratio for a proper combustion..

Loosed or damaged or missing Gas cap :-
The gas cap seals the fuel system to maintain a
fuel pressure for combustion.

The sealing is also helpful in preventing the
release of hydrocarbon fumes into
environment when the vehicle is idle.

If the gas cap is broken or damaged, make sure
to replace it a.s.a.p.

Replacement of catalytic converter :-
Catalytic converter coverts the harmful carbon monoxide into
carbon dioxide before it makes the way to environment.

The reasons that can damage the converter :-
 if the regular maintenance of converter is ignored or
 problem with spark plug and ignition coil..

Problematic spark plugand ignitioncoil:-

coilto producespark for combustion.

Both the coil and spark plug can fail due to several
reasons like ;-
 Due to high under-hood temperature
 A regular wear and tear or
 irregular maintenance etc.

Faulty spark plug wires :-
Spark plug wires send energy in the form of electricityto engine. But
when they become eroded; that disturbs the free flow of energy and
makes the vehicle to stall while idling.

Problematic Mass Airflow Sensor (MAF)
Mass air flow sensor measures the pressure and
humidity in the air that enters to engine..

The symptoms of mass air flow sensor failure
are :-
 Rough idle
 Trouble starting etc.

Maintenance of Exhaust gas
recirculation valve

Helpful in an efficient combustion-
--- it sends the hot exhaust gas to
combustion chamber that warms up the fuel
for an efficient combustion..

If the system fails it affects your vehicle in many ways like :-
 Rough idle
 Engine misfire etc..
