Top 6 Reasons Your Check Engine Light May Be On And Also Blinking by Automotive1(m): 12:38am On Feb 12, 2018




The check engine light is the most mysterious of all of the dashboard lights, as well as the most menacing. It’s one thing when your tire pressure monitoring system light comes on, but it’s a whole different ball game when there could be something wrong with your engine. 

The check engine light can mean many different things, from a loose fuel cap to a misfiring engine. It doesn’t mean you need to immediately pull your car over to the side of the road, but to be safe, it’s best to take it to your mechanic to see what may be wrong.

Reason why your Check Engine Light may be on

1)When your oxygen sensor needs replacing
Your oxygen sensor measures the amount of unburned oxygen in your vehicle’s exhaust system. A car with a failed oxygen sensor will appear to operate normally, but generally will not pass an emissions test.

2)If the fuel cap is loose,damaged or missing
The fuel cap seals the fuel system and helps maintain pressure within the fuel tank. It also prevents petrol fumes from being released into the atmosphere while you aren’t driving your car.

3)When catalytic converter needs replacing
Catalytic converter protect our environment by converting harmful carbon monoxide into carbon dioxide. Without a properly working catalytic converter, your car will be unable to drive, due to inevitable engine failure.

4)Mass airflow sensor needs replacing
It measures the amount of air entering the engine to determine how much fuel is needed to run your engine efficiently. Your engine may experience reduced power.

5)Insufficient exhaust gas recirculation valve flow
EGR works by recirculating a portion of your engine’s exhaust gas back to the engine cylinders. Whenever the EGR valve is blocked or not working normally, engine performance can go down.

6)Spark plugs or plug wires need replacing
Spark plugs ignite the air/fuel mixture in the combustion chamber of your vehicle.Spark plug wires deliver the spark from the ignition coil to the spark plugs. Neglecting to replace your spark plugs will ultimately cause engine failure.

Reason why your check engine light is blinking or flashing

A blinking or flashing dashboard light usually indicates a more severe problem.It usually indicates a severe engine misfire allowing unburned fuel to be dumped into the exhaust system. There it can quickly raise the temperature of the catalytic converter to a point where damage is likely, requiring an expensive repair. 

So when your check-engine light appears either blinking or constant, don’t ignore it. If you postpone repairs, you risk additional damage that can cost thousands of naira to fix.

My car check engine is been there since 2014 when I imported the vehicle to Nigeria we have carried out lot of diagnose on it and the check engine remains there.

Then we concluded that is a rewiring issue... Are we still on point or it's something else

The car is Nissan quest 2000

This is not correct,car will still drive and engine will not fail,but fuel consumption may increase without a properly working catalytic converter.Except the exhaust pipes are blocked by the broken pieces of the cat converter.

Emission tests? Nigerians don't care about the environment, we only care about how to fill our stomach.

Two times my CEL was flashing was:
1. Bent valve. How it happened, i don't know till today. No timing belt cut.

2. Damaged nozzles...2 out of the 6 nozzles weren't working.
