Delphi AS10128 Ignition Knock (Detonation) Sensor

Delphi AS10128 Ignition Knock Sensor

The Delphi AS10128 ignition knock sensor is built for direct-fit service on select Nissan and INFINITI applications. It uses a bolt-on mounting design with a square female connector and two male blade terminals for a straightforward replacement on the original engine harness connection.

Key Features

• Ignition knock (detonation) sensor for engine knock detection and timing control input
• Bolt-on mounting type for OE-style installation
• Square connector shape with 1 female connector and 2 blade terminals
• Terminal configuration: male terminals, 2 total
• Package contents include the ignition knock sensor and instruction sheet
• Delphi OE heritage backed by 100 years of supplier experience with top automakers

Detailed Description

Delphi AS10128 is an ignition knock sensor engineered for vehicles that rely on accurate detonation feedback to help the engine control system manage spark timing. Delphi builds this part using OE experience and application knowledge developed through long-term supplier relationships with major automakers. This part cross-references Beck/Arnley 158-0813 and Standard Ignition KS206 for the same application. It is a direct replacement choice for select INFINITI G35, I35, M45, Q45, QX4, I30 and Nissan Altima, Maxima, and Pathfinder applications listed below. The Delphi AS10128 is a practical service part when replacing a failed knock sensor on these vehicles.

Common Issues This Part May Address

• Knock sensor fault codes stored in the engine control module
• Audible spark knock or detonation under load
• Reduced ignition timing response from a failing sensor signal
• Check engine light related to knock sensor circuit concerns
• Rough engine operation caused by inaccurate detonation feedback

Installation Notes and Tips

Confirm connector shape, terminal count, and mounting style against the original part before installation. Inspect the harness connector and mounting surface for corrosion, damage, or debris before bolting the sensor in place. Use the included instruction sheet during installation and verify all diagnostic trouble codes are cleared after repair. For best results, compare the old sensor to Delphi AS10128 before service on Nissan and INFINITI models.

Quality Assurance

Delphi draws on OE heritage and supplier experience built over a century of automotive manufacturing support. That background is reflected in the design and application coverage of the AS10128 knock sensor for select Nissan and INFINITI vehicles.
