Delphi AS10228 Ignition Knock (Detonation) Sensor

Delphi AS10228 Knock Sensor for Nissan and Infiniti

Delphi AS10228 is an ignition knock sensor built for accurate engine knock detection in select Nissan and Infiniti applications. It is calibrated to OE standards to help deliver reliable readings for engine management systems on vehicles such as the Infiniti G35, FX35, FX45, M35, M45, Q45, and Nissan 350Z, Murano, and Pathfinder.

Key Features

• Ignition knock (detonation) sensor for engine knock monitoring
• OE-developed and OE-validated sensor design
• Tested and calibrated to OE standards for accurate signal output
• 1 square connector with 2 male terminals
• Pin terminal type with screw mounting
• Direct replacement part number AS10228

Detailed Description

Delphi AS10228 is an emission control sensor that monitors engine detonation and sends a signal to the engine control system so timing adjustments can be made when knock is detected. Delphi backs this sensor line with OE development and product validation methods, and each sensor is tested and calibrated to OE standards to support accurate readings and reduce repeat repairs. This part cross-references Standard Ignition KS204 for the same application. If you are replacing a knock sensor on a Nissan 350Z, Infiniti G35, or other listed applications, AS10228 provides the correct OE-style configuration for the factory mounting and connector layout.

What It Helps Address

• Check engine light related to knock sensor circuit faults
• Audible engine pinging or detonation under load
• Incorrect ignition timing caused by faulty knock signal input
• Reduced engine performance from inaccurate sensor readings
• Driveability issues tied to engine control knock detection
