Knock Sensor Harness Guides

How to Replace Your Knock Sensor Harness in Six Steps

If lately you've been seeing your “Check Engine” light turned on, of if you've been experiencing some weird engine problems, then you should never take it for granted. When this happens, you need to have your engine checked right away, as some of its components are probably worn out. One component that you need to check is your knock sensor harness. This part is connected to the knock sensor, which is responsible for sensing vibrations caused by engine knock or detonation. The sensor helps protect the engine from getting damage, that's why it is important to ensure that it is not rusty and always in good condition. You can readily replace your knock sensor harness in just a few steps.

Difficulty level: Moderate

What you'll need:

  • Adjustable wrench
  • Camera (optional)
  • Replacement knock sensor harness

Step 1: Open the hood of your vehicle. Make sure that your engine has cooled down before touching it, since you'll be working near the engine block.

Step 2: Look for the knock sensor part, which is mounted on the engine block near the intake manifold. You can readily see the knock sensor harness attached to it. You may refer to your vehicle's owner's manual to locate the knock sensor harness, if you can't find it.

Step 3: Remove any engine components or brackets that are getting in the way of removing the knock sensor harness. Use a wrench to remove the bolts in a counter-clockwise direction. It would be helpful if you have a camera to take photos of the components before you remove them. This is to help you during re-assembly.

Step 4: Remove the wiring harness from the knock sensor by squeezing in on the tabs that hold the connector in place. Pull the old harness away from the sensor, and replace it with your new part. Make sure that it snaps into place.

Step 5: Check if you also need to replace your entire knock sensor. Look for signs of premature wear like rust and corrosion. It is best to replace the sensor and the harness at once to save your time and effort.

Step 6: Disassemble the components and brackets that you removed to access the sensor. Tighten the bolts using the adjustable wrench in a clockwise direction. Close the hood, and try starting your engine. It should work just fine if you were able to put back the parts in their proper place.

Just like that, your vehicle is ready to roll again. You can finish the installation of your new knock sensor harness in less than an hour. It would be great if you have someone to assist you, especially in disassembly. To ensure that your replacement harness will not wear out easily, make sure that first, it is a high-quality original equipment manufacturer (OEM) part. It is better to invest for this part than to compromise quality by purchasing a cheap aftermarket part. After all, the harness helps keep your engine protected, and it would cost you a lot if you let your engine succumb to damage and premature wear.
