What Is a Knock Sensor?
The is a device that sends a signal to your vehicle’s powertrain control module (PCM) when it detects an engine knock, which occurs when the ignition timing is off. The PCM uses the data to adjust the timing and resolve the excess detonation in the ignition cycle.
How Much Does a Knock Sensor Replacement Cost?
A knock sensor can cost anywhere between $10 and $100, depending on factors like its brand, configuration, and your vehicle’s specifications. It varies based on the rates in your area and your vehicle’s make and model.

Introduction to Knock Sensor
The abnormal noise inside the engine can be detected by one of the major automotive sensors: YZHIDIANF’s knock sensor. It can monitor the vibration and sound of the engine during operation; in particular, when pre-combustion or knock occurs in the combustion chamber, the sensor responds in real-time and sends a signal to the engine control unit. It monitors the real-time knock and dynamically adjusts the ignition time and fuel mixture ratio during the operation of the engine to protect the engine and optimize performance.
Product Function
YZHIDIANF’s knock sensor has many functions and advantages:
1. Accurate monitoring
It can precisely sense the knock of the engine and make sure the response is timely to avoid serious damage to the engine.
2. Improvement in combustion efficiency
The whole idea of feedback helps the ECU to make correct ignition time, allowing fuel to burn completely, thus improving an engine’s fuel economy.
3. Engine long life service
It serves in the early detection of potential knocking problems and reduces component wear and damage for an extension in the life.
4. Easy installation
Simple in design, applied to more model types, and easy to install and replace for vehicle maintenance personnel.
