Walker Products Engine Sensor Line

Walker Products has supplied fuel system and engine management components since 1946. The Walker Products line includes sensors and related engine control parts engineered to meet or exceed OEM standards and specifications, with manufacturing and technical support backed by in-house product and engineering teams. Part number 242-1023 follows that approach for knock sensor replacement across supported GM platforms.

Detailed Description

This ignition knock sensor monitors engine vibration patterns so the control system can respond to detonation events and maintain proper engine operation. Walker 242-1023 is listed for broad GM coverage, including Chevrolet and GMC trucks, vans, SUVs, and performance applications from the 1990 through 1997 model years. It is also referenced for OE cross-application service on vehicles using the same sensor design, including Chevrolet C1500, GMC P3500, and Chevrolet Camaro applications.

This part cross-references Delphi AS10016 for the same application.

What It Helps Address

• Knock sensor fault codes
• Engine pinging or detonation-related drivability concerns
• Rough running caused by inaccurate knock input
• Check engine light conditions tied to knock sensor failure
• Loss of proper ignition timing control on supported GM vehicles

Installation Notes and Tips

Verify connector style, terminal count, and OE reference before installation. This sensor uses a round female connector with a bullet-style terminal arrangement and does not include a wiring harness or mounting hardware. Confirm the vehicle application against the fitment list for your exact year and model, especially on Chevrolet C1500, GMC K1500, and Chevrolet Tahoe platforms.
