Delphi AS10363 Ignition Knock (Detonation) Sensor

Delphi AS10363 Ignition Knock Sensor

Delphi AS10363 is an ignition knock sensor built for accurate engine knock detection and OE-style signal output. It is a direct-fit sensor for a wide range of Hyundai and Kia applications, including Hyundai Sonata, Santa Fe Sport, Elantra N, and Kia Sportage models.

With a 2-terminal male pin connector, oval connector shape, and included wiring harness, this Delphi knock sensor is built for clean electrical connection and consistent calibration to OE standards.

Key Features

• Ignition knock (detonation) sensor for engine timing feedback
• Delphi AS10363 part number for application matching
• OE-standard testing and calibration for accurate readings
• Oval connector with 1 male connector and 2 male terminals
• Wiring harness included; harness length 11.7 in. / 300 mm
• Screw mounting type for direct replacement use
• Fits Hyundai and Kia vehicles across multiple model years

Detailed Description

The Delphi AS10363 knock sensor monitors engine vibration patterns and sends the signal needed for proper ignition control. This helps the engine management system respond to detonation events with the correct timing adjustments. Delphi validates these sensors to OE standards, supporting accurate readings and reducing repeat repairs caused by incorrect sensor output.

Compatible With Hyundai Sonata, Hyundai Santa Fe Sport, Hyundai Elantra N, Kia Optima, Kia Sorento, and Kia Sportage applications, this sensor also cross-references Standard Ignition KS383 and KS427 for the same application. The Delphi AS10363 is a practical OE-style replacement for vehicles that require a screw-mounted knock sensor with an oval 2-pin connector.

What It Helps Solve

• Knock sensor fault codes
• Erratic ignition timing caused by incorrect detonation feedback
• Check engine light related to knock sensor circuit issues
• Engine pinging or spark knock under load
• Driveability problems tied to inaccurate engine knock detection

Installation Notes and Tips

• Verify connector shape, terminal count, and harness length before installation.
• Confirm vehicle application by year, make, and model before ordering.
• Inspect the mounting surface and wiring connector for corrosion or damage.
• Use the screw mounting point specified by the vehicle application.
• After installation, clear diagnostic trouble codes and confirm proper sensor operation.

Quality Assurance

Delphi sensors are developed and validated using OE-focused methods, with calibration checks intended to support accurate signal output and dependable engine management performance. This helps maintain consistent operation across the listed Hyundai and Kia fitments, including Hyundai Sonata and Kia Sportage applications.
