Walker 242-1348 Ignition Knock (Detonation) Sensor
Ignition Knock Sensor for Audi Applications
Walker 242-1348 is an OE replacement ignition knock sensor built to monitor engine vibration and detect detonation events in real time. It is engineered for direct fitment on select Audi models, including the Audi A6 Quattro, Audi A7 Quattro, and Audi Q7, with factory-style electrical connection and OE-matched sensing characteristics.
The Sensor Only line from Walker focuses on direct replacement components that match original equipment requirements for frequency range, sensitivity, and electrical output. This helps the engine control unit respond quickly to knock detection and maintain proper ignition timing under load.
Key Features
- OE replacement ignition knock (detonation) sensor
- Walker Sensor Only product line for direct replacement applications
- Factory-style 2-terminal, pin-style connection
- Female connector with oblong shape
- Male terminal gender for OE-style electrical interface
- Built with heat- and oil-resistant materials for engine bay conditions
- Direct-threaded fitment for original sensor mounting locations
- Part number 242-1348 for application lookup and ordering
Detailed Description
Walker 242-1348 is designed for gasoline engine knock detection where precise vibration sensing is required. The sensor monitors resonant engine frequencies associated with spark knock and sends an electrical signal to the ECU so ignition timing can be adjusted immediately. That response helps protect internal engine components and supports stable drivability. This part number, 242-1348, is specified for select 2016-2018 Audi A6 Quattro, 2016-2018 Audi A7 Quattro, and 2017-2019 Audi Q7 applications.
As part of Walker Products' Sensor Only line, this knock sensor is built as an OE-style replacement rather than a universal component. The design matches original specifications for sensitivity and output, and the connector layout supports factory-style installation on the listed Audi platforms.
Common Issues This Part Can Address
- Knock sensor fault codes such as P0325 or P0330
- Erratic ignition timing caused by inaccurate knock detection
- Spark knock or detonation under acceleration or load
- Reduced fuel economy related to timing correction issues
- Drivability concerns tied to a failed engine knock sensor
Installation Notes and Tips
Verify the original sensor location and connector style before installation. This part uses a pin-type, 2-terminal, female connector with an oblong shape and installs into the original threaded mounting point. Clean the mounting surface and inspect the harness connector for corrosion or damage before connecting the replacement sensor. Confirm the vehicle application by year, make, and model before ordering Walker 242-1348.
Quality Assurance
Walker knock sensors are engineered to OE specifications for frequency response, sensitivity, and electrical output. The Sensor Only line is built for direct replacement use on the listed Audi applications, including Audi A6 Quattro, Audi A7 Quattro, and Audi Q7.
