Detailed Description

Motorad 1KS1043 is an ignition knock sensor designed for Acura RSX models from 2002 through 2006. It converts engine vibration and detonation activity into a signal the ECM can use to adjust ignition timing, helping the engine management system respond to knock events with the correct timing strategy. The 12.0 threaded end diameter supports proper sensor installation in the intended mounting location. This part cross-references Honda 30530PRBA01 for the same application.

Common Issues It May Address

• Knock sensor fault codes related to detonation signal loss
• Rough engine operation caused by incorrect ignition timing input
• Reduced engine performance from inaccurate ECM knock feedback
• Illuminated check engine light tied to sensor circuit concerns
• Audible pinging or spark knock under load

Installation Notes and Tips

Verify the connector, mounting point, and threaded end diameter before installation. Clear diagnostic trouble codes after replacement and confirm that the ECM receives a stable knock signal during engine operation. For Acura RSX fitment, confirm the sensor location matches the original application before tightening to specification.

Quality Assurance

Motorad manufactures this knock sensor to meet or exceed OEM specifications using a tightly controlled piezoceramic element. The part is produced in ISO TS16949 facilities to support consistent sensor output and durability. Part number 1KS1043 is intended for 2002-2006 Acura RSX applications.
