Walker 242-1289 Ignition Knock (Detonation) Sensor
Ignition Knock Sensor for OE Replacement
Walker 242-1289 is a Sensor Only ignition knock sensor built for OE replacement service on select Hyundai and Kia vehicles. It monitors engine vibration and sends the signal the ECU uses to adjust ignition timing when detonation is detected.
Compatible With 2006-2012 Hyundai Veracruz, 2006-2011 Hyundai Azera, 2006-2010 Hyundai Sonata, 2006-2010 Kia Sedona, 2007-2009 Hyundai Santa Fe, 2007-2009 Kia Amanti, and 2007-2008 Hyundai Entourage.
Key Features
- Walker Sensor Only line for direct replacement of the knock sensor, without unrelated components
- OE-style frequency range and sensitivity for accurate knock detection
- Electrical output tuned for the engine control system’s timing response
- Heat- and oil-resistant construction for under-hood durability
- Factory-style fitment with 1 female oblong connector, 2 male spade terminals
- Part number 242-1289 for service matching and catalog lookup
Detailed Description
Walker Products 242-1289 is engineered to match original equipment specifications for knock sensing performance. By detecting the resonant vibration associated with spark knock or detonation, the sensor helps the ECU reduce timing advance in real time and protect the engine from damage. This makes it a direct-fit choice for Hyundai Sonata knock sensor replacement, Hyundai Azera knock sensor service, and Kia Sedona knock sensor repair where OE-style signal accuracy matters.
The Sensor Only product line focuses on the sensing element itself, making it a practical option when the original connector and mounting location are being serviced as part of a standard repair. The unit installs into the original threaded location and uses factory-style electrical connections for straightforward integration. Walker 242-1289 is also a useful reference when searching for a Hyundai Veracruz knock sensor or Kia Amanti knock sensor by part number.
This part cross-references Beck/Arnley 158-0799 and Standard Ignition KS299 for the same application.
What It Helps Address
- Knock sensor fault codes such as P0325 or P0330
- Erratic ignition timing caused by inaccurate detonation feedback
- Reduced fuel economy related to timing correction issues
- Drivability concerns tied to spark knock detection problems
- Engine protection concerns when detonation is not reported correctly
Installation Notes and Tips
Install the sensor in the original threaded location and verify the connector style before service. Clean the mounting surface, inspect the harness for heat damage or corrosion, and confirm the repair with a scan tool after clearing diagnostic trouble codes. For fitment verification, match the vehicle year, make, and model to the listed applications for Walker 242-1289.
Quality Assurance
Walker knock sensors are built to OE replacement standards with materials selected for heat and oil exposure in engine-block and cylinder-head environments. The design is tuned for the specified engine frequency range and electrical output to support accurate knock detection on the listed Hyundai and Kia applications.
