A-Premium Ignition Knock Detonation Sensor for Hyundai & Kia — 2‑Pin Direct‑Fit Replacement with 1‑Year Warranty

The A-Premium Ignition Knock Detonation Sensor is a direct-replacement 2-pin sensor designed to detect engine knock on select Hyundai and Kia 4-cylinder models, restoring proper timing control and drivability.

Installed where the engine management system expects feedback, this knock/ignition detonation sensor senses abnormal combustion and sends rapid signals to the ECU so ignition timing can be adjusted. It’s built to match factory mounting and connector style for an easy swap on many Hyundai and Kia vehicles, and ships as a single boxed unit with a one-year unlimited-mileage warranty from A-Premium.

This sensor covers a broad list of compatible model years and engine sizes. Fitment includes multiple Santa Fe, Santa Fe Sport, Sonata, Tucson, Forte, Forte Koup, Forte5, Magentis, Optima, Rondo, Sorento, and Sportage variants with L4 2.0L and 2.4L gasoline engines, plus certain 2.0L hybrid/PHEV Sonatas.

• Terminal quantity: 2 pins; terminal type: blade for stable contact
• Designed to withstand engine bay temperatures and vibrations common to Hyundai/Kia 4-cylinder layouts
• Backed by a one-year unlimited-mileage guarantee for peace of mind

How can I confirm this is the right part before I buy?

Verify fitment by checking the vehicle year, make, model, engine displacement, and emissions spec against the fitment list or use an online confirmed-fit tool. You can also compare the OEM/reference numbers printed above with your existing sensor to ensure a match.
