A bad knock sensor may also not let the engine accelerate properly while driving on the highway, and cause the vehicle to lose fuel mileage. ... Once the computer realizes the knock sensor is not working properly, your vehicle will most likely lose power.

What happens if a knock sensor goes bad?

Pinging Noise From the Engine

If the knock sensor fails, the PCM may not recognize or correct spark knock. As a result, you may hear a metallic pinging noise from the engine. The noise is often most noticeable when the engine is under a heavy load.

What sound does a bad knock sensor make?

Noises. If the knock sensor is not working properly, you will likely hear sounds emitting from the engine. You may hear loud thumping noises that become louder over time. The noise is a result of fuel and air igniting inside the cylinder, instead of reaching the point of combustion.

What happens if you don't replace knock sensor?

If the knock sensor is not working then the engine could start pinging without the computer being able to detect it. ... If the knock sensor is bad through testing then if it is not replaced the engine may have reduced power, loss of fuel mileage, and hesitations.

A knock sensor causing engine shaking or rough idle often results in a service engine light or code warning. The driver can check against factory code lists for that particular vehicle to confirm the cause, then inspect the knock sensor for proper resistance, replacing it if necessary.

Can a bad spark plug cause a knock sensor code?

Will a bad spark plug cause a knock? Yes, if your plugs remain tainted out, it can create a misfire which throws the timing away. If the timing is thrown out, then it throws knock code. If the knock code suspects vibration and suspects are misfiring, it retards the timing, which will cause a knock code.
