Crash Impact 77930-SNA-A320 Knock Sensor: Accurate engine knock detection
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.
