• Part number: AS10325
• Ignition knock (detonation) sensor for engine timing feedback
• 1 connector, square connector shape
• 2 terminals, male connector and male terminal design
• Screw mounting type
• OE-standard testing and calibration for accurate sensor output
• Package contents: ignition knock sensor

Detailed Product Overview

The Delphi AS10325 knock sensor monitors engine vibration patterns and sends signal data to the vehicle’s control system so ignition timing can be adjusted when detonation is detected. Delphi validates and calibrates its sensors to OE standards, which supports accurate readings and consistent performance in the applications listed above. This part number, AS10325, is a direct-fit style replacement for select Nissan and INFINITI vehicles, including Armada, Altima, Rogue, QX50, QX55, and QX80 models.

This part cross-references Standard Ignition KS457 for the same application.

What This Sensor Helps Address

• Knock sensor fault codes
• Engine pinging or detonation-related drivability concerns
• Incorrect ignition timing feedback
• Rough running caused by inaccurate knock signal input
• Check engine light conditions tied to knock sensor circuit issues

Installation Notes and Tips

Verify connector style, terminal count, and mounting type before installation. This sensor uses a single square male connector with two male terminals and screw mounting. Mounting hardware is not included, so reuse or source the required fasteners separately if needed. Confirm vehicle-specific fitment for your exact year and model before ordering AS10325.
