Walker 242-1269 Ignition Knock (Detonation) Sensor
Walker 242-1269 Ignition Knock Sensor
Walker 242-1269 is an OE replacement ignition knock sensor for gasoline engines that need accurate detonation detection and factory-style electrical connection. It is built for direct replacement service on 2002-2003 Nissan Altima and 2002-2003 Nissan Sentra applications.
Sensor Only Product Line
Walker’s Sensor Only line focuses on replacement sensors engineered to match OE specifications for signal range, sensitivity, and output. This approach helps restore proper engine control input without changing the original system design.
Key Features
- OE replacement knock sensor for engine detonation monitoring
- Engineered to match OE frequency range, sensitivity, and electrical output
- Heat- and oil-resistant construction for engine-block and cylinder-head environments
- Direct-fit threaded installation with factory-style electrical terminals
- Female connector with rectangle shape, 1 connector, 2 terminals
- Part number 242-1269 for catalog and cross-reference use
Detailed Description
The Walker 242-1269 ignition knock sensor monitors engine vibration and sends a signal to the ECU so ignition timing can be adjusted when knock is detected. That real-time timing correction helps protect the engine from spark knock, reduce drivability complaints, and maintain proper combustion control. This sensor is a direct replacement for 2002-2003 Nissan Altima and 2002-2003 Nissan Sentra models listed in the fitment data, making it a practical choice when servicing a knock sensor fault or restoring original engine management response. This part cross-references Standard Ignition KS209 for the same application.
What It Helps Fix
- Knock sensor fault codes such as P0325 or P0330
- Erratic ignition timing caused by inaccurate knock detection
- Spark knock or detonation under load
- Reduced fuel economy related to timing correction issues
- Drivability problems tied to failed engine vibration sensing
Installation Notes and Tips
Install the sensor in the original threaded location and connect it using the factory-style terminal layout. Verify connector shape, terminal count, and vehicle application before installation. For best results, inspect the harness and mounting surface for damage or contamination during service.
Quality Assurance
Walker designs this sensor as an OE replacement component built to match the original application requirements for fit, signal response, and durability in high-heat, oil-exposed engine locations.
