Walker 242-1272 Ignition Knock (Detonation) Sensor
Ignition Knock Sensor for Mazda 6
Walker 242-1272 is an OE replacement ignition knock sensor for 2003-2008 Mazda 6 applications. It monitors engine vibration and sends the signal the ECU uses to adjust ignition timing when detonation is detected.
Key Features
- OE replacement knock sensor for gasoline engine knock detection
- Engineered to match OE frequency range, sensitivity, and electrical output
- Factory-style square connector with 2 blade terminals
- Female connector with male terminals for direct electrical connection
- Wiring harness included for a cleaner service replacement
- Heat- and oil-resistant construction for engine-block and cylinder-head environments
- Direct-fit design for the original threaded mounting location
Product Details
Walker Sensor Only line focuses on direct replacement engine management components built to restore factory-style signal accuracy. This knock sensor is tuned to detect the resonant frequency associated with detonation in the Mazda 6 platform, helping the ECU respond with precise spark retard when abnormal combustion is present. Walker 242-1272 is built for the demands of the engine bay and uses OE-style fitment and electrical connection points for straightforward service replacement.
This part cross-references Standard Ignition KS219 for the same application.
What It Helps Address
- Diagnostic trouble codes such as P0325 or P0330
- Audible spark knock or pinging under load
- Incorrect ignition timing response from a failed sensor signal
- Reduced fuel economy caused by detonation-related timing changes
- Drivability issues tied to inaccurate knock detection
Installation Notes
Fits 2003-2008 Mazda 6, N/A. Verify the original sensor location, connector shape, and threaded mounting point before installation. The square 1-connector, 2-terminal design is intended to connect to the factory harness, and the included wiring harness supports replacement of the original sensor assembly. No mounting hardware is included.
Quality Assurance
Walker knock sensors are manufactured to OE specifications for signal response and electrical output, with materials selected for heat and oil exposure in engine applications. Part number 242-1272 is built to restore proper knock detection and support stable ignition control on the Mazda 6.
