Walker Products 242-1414 Ignition Knock Detonation Sensor

The Walker Products 242-1414 is a direct-fit ignition knock (detonation) sensor engineered to restore proper engine management function. Knock sensors monitor engine block vibrations associated with detonation or pinging and relay that signal to the ECM, which then retards ignition timing to protect the engine from damage.

Key Features:

• OE Fit, Form & Function: Engineered and tested to meet or exceed original equipment performance and durability standards
• High-Quality Materials: Built to withstand the harsh thermal and vibrational conditions of the engine environment for long-lasting reliability
• Direct-Fit Installation: Designed as a drop-in replacement to minimize downtime and simplify installation
• Engine Protection: Accurate detonation detection safeguards the engine against knock-related damage
• Optimized Performance: Precise knock monitoring helps the ECM optimize ignition timing and combustion efficiency, supporting better fuel economy
• ISO 9001 / IATF 16949 Certified: Manufactured under Walker Products' rigorous quality management standards

Common symptoms that indicate a failed knock sensor include audible engine knock or pinging and a noticeable loss of power. Service is recommended when these symptoms develop or when diagnostic testing reveals a faulty sensor signal. Walker Products has been supplying the automotive aftermarket with quality engine management and fuel system components since 1946.
