Product Details

Standard Ignition KS541 is built for vehicles that rely on accurate knock detection to support proper engine control. This sensor mounts with a bolt-mount design and connects through a 2-terminal male blade interface, making it a practical replacement for a worn or failed knock sensor on the Nissan Sentra. This part cross-references Nissan OE-style part number 220605TA0A for the same application.

Common Problems It Can Address

  • Knock sensor fault codes
  • Engine pinging or detonation-related drivability concerns
  • Reduced engine performance from inaccurate knock feedback
  • Check engine light related to the knock sensor circuit
  • Intermittent sensor signal issues from a damaged connector or sensor body

Installation Notes

Verify connector style, terminal count, and mounting location before installation. The sensor uses a plug-in connector and bolt-mount attachment, so the mating harness and mounting point should match the original configuration on the vehicle. For best results, inspect the connector terminals and surrounding wiring for corrosion or damage before replacing the sensor.

Quality Assurance

Standard Ignition supplies replacement electrical and engine management components for service applications. KS541 is listed for direct fitment on 2020-2024 Nissan Sentra models and follows the specified terminal, connector, and mounting configuration for that application.
