Delphi AS10297 Ignition Knock (Detonation) Sensor

Delphi AS10297 Ignition Knock Sensor

The Delphi AS10297 ignition knock sensor is built for accurate engine knock detection in select Nissan applications. It uses OE-calibrated testing and validation to deliver consistent readings that support proper ignition timing control and help reduce repeat repairs.

Key Features

• Ignition knock (detonation) sensor for engine knock monitoring
• Delphi OE-developed and OE-calibrated sensor design
• 1 rectangle connector with 2 male terminals
• Pin terminal type for direct electrical connection
• Package contents: ignition knock sensor only
• Part number: AS10297

Detailed Description

Delphi AS10297 is an emission control sensor that monitors engine detonation and sends the signal needed for the engine control system to adjust timing. Accurate knock sensing is important for drivability, fuel control, and engine protection, especially in vehicles that rely on precise ignition feedback. This sensor is a direct-fit option for select Nissan Frontier, Nissan Xterra, Nissan Quest, and Nissan Pathfinder models, including Fits 1999-2004 Nissan Frontier, N/A; Fits 2000-2004 Nissan Xterra, N/A; Fits 1999-2002 Nissan Quest, N/A; and Fits 2000 Nissan Pathfinder, N/A. The Delphi AS10297 is engineered and calibrated to OE standards for dependable signal output.

This part cross-references Standard Ignition KS107 for the same application.

What It Helps Address

• Knock sensor fault codes
• Engine pinging or detonation under load
• Incorrect ignition timing response
• Rough running caused by inaccurate knock feedback
• Repeat repairs from inconsistent sensor readings

Installation Notes and Tips

Verify connector style, terminal count, and mounting location before installation. This sensor uses a single rectangle connector with two male terminals and does not include mounting hardware. Confirm the vehicle application against the listed Nissan Frontier, Xterra, Quest, or Pathfinder fitment before replacing the original unit.

Quality Assurance

Delphi validates its sensors through OE development methods and calibration testing to support accurate readings and consistent performance. That OE-focused process helps maintain signal quality across the listed Nissan applications.
