Detailed Description

Standard Ignition KS531 is an emission control sensor that monitors engine knock signals and sends data to the engine management system. For Genesis G80 and Genesis G90 vehicles, this sensor supports accurate knock detection so the ECU can respond to combustion irregularities. If you are searching for a Genesis G80 knock sensor front or a Genesis G90 knock sensor front, KS531 matches the listed OE-style fitment and connector layout.

This part cross-references Hyundai/Kia OE numbers 393203F130 and aftermarket references such as DKS276 for the same application. The KS531 part number is also useful when comparing replacement options for 2017 Genesis G80, 2018-2020 Genesis G80, 2017-2019 Genesis G90, and 2021-2022 Genesis G90 front sensor locations.

What It Helps Address

• Knock sensor fault codes
• Engine pinging or detonation-related drivability concerns
• Reduced ignition timing control from inaccurate knock feedback
• Check engine light concerns tied to the knock sensor circuit
• Rough engine operation caused by a failing front knock sensor

Installation Notes and Tips

Verify the connector style, terminal count, and front mounting location before installation. The KS531 uses a bolt-mount design and a single plug-in connector, so the harness should seat fully and the sensor should be secured to the specified mounting point. Confirm fitment for your exact Genesis G80 or Genesis G90 year and engine configuration before replacing the sensor.
