Walker Products Ignition Knock Detonation Sensor Full Service Kit

The Walker Products Ignition Knock (Detonation) Sensor Full Service Kit is a replacement knock sensor (also called a detonation sensor) that helps restore proper knock detection and spark timing control. The knock sensor listens for the vibration of engine knock, which is an unplanned second combustion event in the cylinder. It sends an electrical signal to the engine control unit (ECU). The ECU then adjusts timing to help protect the engine.

Key Features:

• Full Service Kit (FSK): Pairs the sensor with a vehicle-side mating pigtail, as described in Walker's knock sensor program literature
• OE-matched performance: Engineered and tested to OE specifications for fit, form and function, including range, sensitivity and electrical output
• Dependable construction: Made with quality materials designed to hold up under demanding underhood conditions
• ECU signal integration: Provides the electrical output signal the engine computer uses for knock detection and spark timing control
• Broad program coverage: Walker's knock sensor line covers domestic and import cars and light trucks, including gas, diesel, flex fuel and LPG/CNG applications

A failing knock sensor can cause a check engine light, reduced performance, or poor fuel economy. Replacing it with a Walker Full Service Kit gives you a sensor and matching connector hardware from a trusted ignition and emissions brand. Choose the child item that matches your application.
