Detailed Description

The Motorad 1KS1027 is an ignition knock (detonation) sensor used to detect abnormal combustion and relay that information to the engine control module. On applications such as the Acura EL and Honda Civic, this signal helps the ECM adjust ignition timing based on real engine conditions. This part cross-references Honda OE numbers 30530PLE004 and 30530PLMA01 for the same application.

Common Issues This Part May Address

• Knock sensor fault codes related to detonation signal loss or irregular output
• Engine pinging or spark knock under load
• Reduced ignition timing control from inaccurate sensor feedback
• Check engine light concerns tied to knock sensor circuit faults
• Driveability issues caused by incorrect ECM timing adjustments

Installation Notes and Tips

Verify the vehicle year and engine application before ordering. For best results, inspect the sensor connector, wiring, and mounting surface during replacement, and clear diagnostic trouble codes after installation. Confirm the part number 1KS1027 against the original sensor and vehicle service information for the exact application.

Quality Assurance

Motorad manufactures this knock sensor to meet or exceed OEM specifications using controlled production standards and a high-quality piezoceramic element for consistent performance.
