Detailed Description

Walker 242-1352 is designed for right-side applications where precise knock sensing is required to help the ECU respond to spark knock before it leads to drivability concerns or internal engine damage. The sensor is built to OE dimensions and electrical characteristics, with a 356 mm length, 8.45 mm mounting hole diameter, and no gasket, seal, harness, or mounting bracket included. For buyers searching for a right side knock sensor for 2013-2018 Hyundai Santa Fe, 2012-2017 Hyundai Azera, 2011-2012 Kia Sedona, or 2014-2016 Kia Cadenza, this part number 242-1352 matches the listed application data.

This part cross-references no listed aftermarket part numbers for the same application.

What It Helps Address

• Knock sensor fault codes such as P0325 or P0330
• Incorrect ignition timing caused by failed knock detection
• Engine pinging or detonation under load
• Reduced fuel economy from timing control issues
• Drivability problems related to inaccurate knock feedback

Installation Notes and Tips

Install the sensor in the original threaded location and connect it using the factory-style terminal interface. Verify the right-side application before ordering, since fitment is position-specific. Inspect the mounting surface and connector condition during replacement, and confirm the harness routing is clear of heat and abrasion. Part number 242-1352 is listed for sensor-only replacement use.
