Walker 242-1066 Ignition Knock (Detonation) Sensor

Ignition Knock Sensor Overview

Walker 242-1066 is an OE replacement ignition knock sensor for gasoline engine management systems. It monitors engine vibration so the ECU can adjust ignition timing and reduce spark knock that can affect drivability and engine protection.

Compatible With Chrysler Sebring, Dodge Stratus, Mitsubishi Eclipse, Mitsubishi Diamante, Mitsubishi Galant, Mitsubishi 3000GT, and Dodge Stealth applications listed below, this sensor is built to match OE frequency range, sensitivity, and electrical output. The 242-1066 uses a rectangular female connector with a blade-style terminal layout and includes a wiring harness for factory-style electrical connection.

• OE replacement knock sensor for engine control systems
• Matches OE specifications for frequency range, sensitivity, and output
• Factory-style rectangular connector with blade terminals
• Heat- and oil-resistant construction for engine bay conditions
• Direct threaded installation into the original sensor location
