• 250 mm length for application-specific fitment
• Delphi AS10235 replacement sensor for select Hyundai and Kia vehicles

Detailed Product Description

The Delphi AS10235 ignition knock sensor monitors engine vibration patterns and sends a signal to the engine control system when detonation is detected. Delphi validates its sensors to OE standards, helping ensure accurate readings that support proper engine management. This part cross-references Standard Ignition KS256 for the same application.

Use this Delphi knock sensor when servicing a Hyundai Elantra, Hyundai Tiburon, Hyundai Tucson, Kia Spectra, Kia Spectra5, or Kia Sportage equipped with the listed fitments. The AS10235 is built with a male connector interface, screw mounting, and a square connector shape to match the original sensor style on covered vehicles.

Common Issues This Part May Address

• Knock sensor fault codes
• Audible pinging or detonation under load
• Reduced engine performance from incorrect knock signal input
• Check engine light related to knock sensor circuit faults
• Driveability concerns caused by inaccurate engine timing correction

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. Inspect the harness and mounting surface for corrosion, damage, or contamination that could affect sensor readings. Follow the vehicle service procedure for torque and routing, and confirm the repair with a scan tool after installation.

Quality Assurance

Delphi sensors are developed with OE-focused validation methods and tested and calibrated to OE standards to support accurate signal output and reduce repeat repairs.
