Motorad 1KS1012 Ignition Knock (Detonation) Sensor

Motorad Knock Sensor 1KS1012

The Motorad 1KS1012 ignition knock sensor monitors engine knock frequencies and sends accurate signal data to the ECM for ignition timing control. It is a direct-fit emission control sensor for select Honda, Acura, and Isuzu applications, including Honda Accord, Prelude, Odyssey, Acura CL, and Isuzu Oasis models.

• Threaded end diameter: 12.0 mm
• Piezoceramic sensing element built to tight manufacturing tolerances
• Engineered to meet or exceed OEM specifications
• Designed for accurate knock detection across a wide range of engine frequencies
• Manufactured in ISO TS16949 facilities

Detailed Product Overview

This Motorad knock sensor is designed to help the engine control module interpret detonation signals and adjust ignition timing accordingly. By providing precise feedback from the engine block, the 1KS1012 supports stable combustion control in vehicles such as the 1998-2002 Honda Accord and 1997-2001 Honda Prelude. It is also listed for 1998-1999 Acura CL, 1998-1999 Isuzu Oasis, and 1998 Honda Odyssey applications.

This part cross-references Honda OE numbers 30530P5M003 and 30530P5M013 for the same application.

What It Helps Address

• Knock sensor fault codes related to detonation detection
• Erratic ignition timing caused by inaccurate sensor input
• Engine pinging or spark knock under load
• Reduced drivability from poor ECM knock feedback
• Check engine light concerns tied to knock sensor performance

Installation Notes and Tips

Verify the threaded end diameter and connector style against the original sensor before installation.
