How To Remove Knock Sensor

If you’ve bought a home in a city that has age restrictions, it’s likely that your house has a “knock sensor garage door opener” installed. Recent advances in technology have allowed these sensors to be installed in many different types of buildings, including single unit homes and apartments. The knock proximity sensor is the ultimate sentry for better homes and better health.

The Benefits of a Knock Sensor

The knock sensor is a device in the engine that alerts the car when the car knocks or “knocks” against something. When this transpires, the engine tells it to stop spinning at that exact moment and start again when there’s no more “knocking”. The benefits of a knock sensor include avoiding potential engine damage which saves your engine as well as exhaust pipes up to 70% of fuel, reducing carbon emissions by 40%, and decreasing your maintenance cost.

What can be done if you have a knock sensor in your vehicle?

One of the most frustrating parts of owning a new car is when you hit something and your light-up knock sensor begins to beep a loud alarm. Sometimes drivers get annoyed by the alarm and remove it altogether, which is not recommended. You must have the entire knocking unit taken out if it has been knocked off or broken by curbs, shopping carts or other vehicles. You might find some new knock sensors at your local auto parts store or on eBay for about $60. It’s worth repairing the sensor for just $50 to keep your vehicle in top shape!

How to remove a knock sensor without having to change the engine

If a person wants to replace the knock sensor in their vehicle, they need to be mindful that it can also take a while before it’s replaced. It is recommended that they don’t do so if the engine isn’t worn down or has many miles. If someone wanted to change their knock sensor, they must remove it completely by finding out how it fits inside of the engine and drilling through the body.

All you need to know about removing a knock sensor

The purpose of the knock sensor is to tell the engine when it needs to adjust smoothing power. It’s a little paddle called the knock sensor, and it’s mounted on one of the piston rods just below where they come out of the cylinder head. When you start a car with a knock sensor, then every time that piston comes up above 5,000rev/min in its stroke, it will split air across the two pairs of valves into an intake and exhaust valve. Without a knock sensor, sometimes your car will experience misfires and backfires at startup due to this excessive vibration in the piston rod assembly hitting against either the retaining spring or fuel control lower mount bolt.


Using the knock sensor is a popular way to find any car problems. When all else fails, this is one of the first tests someone will perform. This sensor watches for knocks and movement inside the engine to give you peace of mind and stop your check engine light from coming on.
