This is a genuine HONDA replacement component, part number 30530RB0004. The knock sensor is a critical part of your vehicle's engine management system. Its primary function is to detect abnormal combustion, commonly known as engine knock or pinging. When the knock sensor detects this phenomenon, it sends a signal to the engine control unit (ECU). The ECU then adjusts ignition timing to retard the spark, thereby preventing further knocking. This process is vital for protecting your engine from potential damage caused by pre-ignition or detonation. Replacing a faulty knock sensor with this OEM part ensures that your HONDA's engine operates efficiently and safely. It helps maintain optimal power delivery, fuel economy, and reduces the risk of costly internal engine repairs.
