Detailed Description

Standard Ignition KS457 is an engine knock sensor used to monitor detonation and send signal input to the engine management system. This helps the vehicle control ignition timing based on combustion conditions. The KS457 part number is listed for select Nissan Altima, Nissan Armada, Nissan Rogue, and INFINITI QX80 applications, making it a focused replacement for vehicles that require this specific sensor configuration.

This part cross-references Beck/Arnley 158-1818 and Delphi AS10325 for the same application.

What It Helps Address

• Knock sensor fault codes related to detonation detection
• Rough engine operation caused by incorrect ignition timing input
• Check engine light concerns tied to the knock sensor circuit
• Reduced engine response from inaccurate sensor feedback
• Driveability issues on Nissan Armada, Nissan Altima, Nissan Rogue, and INFINITI QX80 models

Installation Notes and Tips

• Verify connector shape, terminal count, and mounting style before installation.
• Use the bolt-on mounting point specified for the vehicle application.
• Inspect the harness connector for corrosion, bent terminals, or heat damage before connecting KS457.
• Confirm the sensor location on the engine, especially on the 2017 Nissan Armada noted as on top of engine.
• Clear diagnostic trouble codes and verify system operation after installation.

Quality Assurance

Standard Ignition replacement sensors are built to match the electrical and mounting requirements of the listed applications. KS457 is cataloged for direct replacement use on confirmed Nissan and INFINITI fitments.
