Walker 242-1440 Ignition Knock (Detonation) Sensor
Walker Knock Sensor 242-1440 Overview
Walker 242-1440 is an OE replacement ignition knock sensor for gasoline engine management systems. It monitors engine vibration and sends the signal the ECU uses to adjust ignition timing when detonation is detected.
This Sensor Only line focuses on direct-fit replacement parts built to OE specifications for frequency range, sensitivity, and electrical output. It is a practical choice for diagnosing knock sensor faults on 2021-2022 Ford Transit Connect and 2021-2022 Lincoln Corsair applications.
Key Features
- OE replacement ignition knock (detonation) sensor
- Connector quantity: 1
- Connector shape: square
- Terminal quantity: 2
- Connector gender: male
- Terminal gender: female
- Wiring harness included: yes
- Built with heat- and oil-resistant materials for engine-bay conditions
- Direct-fit design for factory threaded mounting locations
Product Details
Walker Sensor Only 242-1440 is engineered to detect the resonant frequency associated with engine knock so the control module can reduce spark advance when detonation occurs. That helps maintain proper ignition control and supports stable engine operation. The part number 242-1440 is also a useful reference when sourcing a replacement for a failed knock sensor on Ford Transit Connect or Lincoln Corsair vehicles.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
Common Issues This Part May Resolve
- Knock sensor fault codes such as P0325 or P0330
- Erratic ignition timing caused by a failed detonation signal
- Audible spark knock under load
- Reduced fuel economy related to incorrect timing correction
- Drivability concerns tied to inaccurate engine vibration sensing
Installation Notes and Tips
Verify the connector style, terminal count, and threaded mounting location before installation. The square male connector with two female terminals should match the factory harness on the listed applications. Clean the mounting surface and follow the vehicle service procedure for torque and connector routing. Confirm the part number 242-1440 against the original sensor before final assembly.
Quality Assurance
Walker builds this knock sensor to OE replacement standards for fit, electrical output, and sensing range. The Sensor Only product line is focused on direct replacement components that match factory requirements for the listed Ford Transit Connect and Lincoln Corsair applications.
