  • Produced in ISO TS16949 manufacturing facilities
  • Direct replacement for Motorad 1KS1031 and cross-reference applications

Detailed Description

Motorad 1KS1031 is an ignition knock (detonation) sensor designed for vehicles that rely on precise knock detection to manage spark timing and engine performance. By sending accurate knock information to the engine control module, this sensor helps the ECM respond correctly under changing load and combustion conditions. This part cross-references GM OE numbers 12605738 and 12636736 for the same application.

Compatible With Chevrolet Equinox, Chevrolet Malibu, Chevrolet Camaro, GMC Terrain, Buick Enclave, and other listed GM platforms from 2009 through 2024, this sensor is a practical OE-style replacement for diagnosing knock sensor faults and restoring proper engine feedback. The Motorad 1KS1031 name is also used for interchange lookup when matching the correct emission control sensor.

What It Helps Address

  • Knock sensor fault codes
  • Erratic ignition timing caused by inaccurate knock input
  • Reduced engine response related to detonation sensing issues
  • Check engine light concerns tied to knock sensor circuit problems
  • Driveability complaints on GM vehicles with knock sensor failures

Installation Notes and Tips

Verify the original part number and vehicle application before installation. Inspect the connector, wiring, and mounting surface for corrosion or damage before replacing the sensor. After installation, clear diagnostic trouble codes and confirm proper ECM communication with a scan tool.

Quality Assurance

Motorad manufactures this sensor to meet or exceed OEM specifications in ISO TS16949 facilities, with a piezoceramic element built to tight tolerances for consistent signal output and durability.
