Engine knocking in your Honda Civic? That unsettling pinging sound isn't just annoying—it's a sign of trouble. Fuel burning unevenly in the cylinders can sap power, hike emissions, and even lead to costly engine damage over time. Enter the Crash Impact Knock Sensor, a small but mighty component designed for 2006–2011 Civics. It listens for those knocks and pings, feeding data to the engine control unit (ECU) to fine-tune ignition timing on the fly. The result? Smoother operation, better fuel efficiency, and a happier engine.
For DIYers or pros, this sensor is a straightforward fix. Grab some basic tools, swap it in, and you're back to optimal performance without breaking the bank. No more worrying about that telltale noise or power dip—just reliable driving, mile after mile.

As an impulsive buyer, I grabbed this hoping for a quick fix for my Civic's engine noise, and it delivered on that front—no more knocks, and fuel efficiency seems a tad better. But I expected more durability and less heat; it does the job but feels a bit cheap. For the price, it's okay, but I might look for something sturdier next time if issues pop up again. Happy it worked, but keeping an eye on it.
- Pros: The part was quite easy to install with basic tools, and it did stop that annoying pinging sound right away. I noticed the engine running smoother and felt a bit more pep when accelerating, which was a relief.
- Cons: It runs warm after a bit of driving, which had me a bit worried, and the delivery was delayed a day, though that was fine in the end. I'm not fully convinced it'll last long-term based on how it seemed to me.
