Delphi AS10268 Ignition Knock (Detonation) Sensor

Delphi AS10268 Ignition Knock Sensor

The Delphi AS10268 ignition knock sensor is a bolt-on, OE-style replacement built for Ford and Mercury applications that rely on accurate detonation detection. It uses a square, single-connector design with blade terminals to support a direct electrical connection and consistent signal transfer.

Backed by Delphi’s OE heritage and more than 100 years of supplier experience, this sensor reflects the engineering knowledge used in parts supplied to major automakers. It is a practical choice for drivers searching for a knock sensor for a 1999-2010 Ford Explorer, 2005-2010 Ford Mustang, or 1999-2010 Mercury Mountaineer.

Detailed Description

Delphi AS10268 is engineered for vehicles that depend on knock sensing to help the engine control system monitor detonation and adjust operation accordingly. It is a direct-fit style replacement for a wide range of Ford Ranger, Ford Explorer, Ford Explorer Sport Trac, Ford Mustang, Mercury Mountaineer, Ford Explorer Sport, and select Econoline applications. If you are replacing a worn or failed sensor on a 2000-2011 Ford Ranger or a 1999-2010 Ford Explorer, this part number AS10268 matches the application family used across those platforms.

This part cross-references Standard Ignition KS126 for the same application.

What It Helps Address

• Knock sensor fault codes
• Engine pinging or detonation-related drivability concerns
• Unstable ignition timing control from a failed sensor signal
• Check engine light conditions tied to knock sensor circuit issues
• Loss of accurate engine knock detection in Ford and Mercury applications

Installation Notes and Tips

Verify connector shape, terminal style, and mounting type before installation. This Delphi AS10268 uses a bolt-on design with one square connector, so matching the electrical plug and mounting location is important for proper fitment. Review the included instruction sheet and confirm the vehicle application against the exact year and model before replacing the sensor.
