What are the Signs Associated With a Failing Knock Sensor

Engine knock, pre-ignition & pre-detonation are explosions in the combustion chamber.

Engine knock is only harmful when it occurs at high loads.

These knock sensors are designed to detect these unplanned explosions.

Here are the signs of a failing knock sensor in your car.

Illumination of engine warning light

One of the first signs you will notice is the illumination of warning light.

You should get the vehicle inspected when you see the warning light on the dashboard.

There can be many reasons behind the illumination of the warning light.

You shouldn’t ignore the warning light & get your car inspected.

Abnormal noise

When the knock sensor malfunctions, you will get to hear loud noises from your car.

The longer you take to fix the problem, the louder those noises will become.

The noise occurs due to the ignition of the air and fuel mixture inside the cylinder.

When the mixture reaches the combustion point it explodes.

Poor engine performance

Poor acceleration is a sign of a failing knock sensor in your car.

The worst sign is when the internal engine components become damaged.

You will also experience a burning smell coming from the engine of your car.

The fuel economy of your car will also reduce drastically.

These are the signs associated with a failing knock sensor in your car.

Take your car to a certified repair shop to get the knock sensor replaced.
