Deciphering What Check Engine Light Means

There are a plethora of malfunctions that the Check Engine light could mean – From something as trivial as a loose gas cap to something major like faulty spark plugs. It usually means a visit to the workshop after which you generally end up with a lighter wallet.

What is the check engine light?

Better known as the MIL (Malfunction Indicator Light), the check engine light is a signal from the cars “Engine computer” that something is wrong. And yes, your car has a computer called the ECU doing all the math to run more efficiently. Every time you put your car into the ignition, the ECU runs a number of the tests across the powertrain (everything essential for a car to keep delivering power to the wheels) to ensure everything is functional. Let’s figure out what it means.

If it Blinks, it’s Serious. Period.

If the check engine light blinks while you’re driving, you should immediately bring your car to a halt at a safe location. Continuing to drive is such a state could unleash heavy damage to some expensive parts of the car. At times like these, you should definitely consider, getting your car towed or getting it checked by a professional mechanic.

But if it’s a Steady Light?

It isn’t something major or an emergency. You can continue driving but should visit a local workshop, as soon as you can, for a quick check-up.

The Most Common Reasons the Check Engine Light Comes on:

It’s unlikely for it to malfunction if the car is maintained well. But if the catalytic converter ends up malfunctioning and requires replacement, it could cost you upwards of Rs.6000.

But if the sensor actually stops working, again it’s a pretty costly affair to replace. These complex electronics are hard to fix.

If the light goes on, quickly check if it’s because of the petrol cap. Tighten if it’s loose or if you see the damage, replace the cap. You should see the light turn off soon enough.

Faulty readings could mean in poor performance and if left this way could eventually damage the catalytic converter which can cost a fortune to replace.

If it’s indeed the bad spark plugs, your local mechanic can replace these in a jiffy and they don’t cost much either.

There will be times when even your mechanic finds it hard to figure out what’s wrong and it could be just some loose sensor wires. But if your “check engine” light is coming on too often, your car is getting old and you’re asking too much from it. It’s about time you sell your old car and let it rest in peace.
