Product Details

The Walker Products 242-1016 knock sensor is used to monitor engine vibration patterns associated with detonation so the control system can adjust timing as needed. It is a direct-fit service part for many 1987-1995 GM passenger cars, vans, and trucks, including applications such as 1991-1995 Buick Park Avenue, 1990-1995 Chevrolet Camaro, 1992-1995 Chevrolet Corvette, 1993-1995 GMC G2500, and 1988-1993 Pontiac Grand Am. If you are replacing a failed knock sensor on a Buick, Chevrolet, or GMC platform, 242-1016 provides a cataloged replacement option for the listed vehicles.

This part cross-references Standard Ignition KS3 for the same application.

What It Helps Address

• Knock sensor fault codes
• Audible spark knock or pinging under load
• Erratic ignition timing control
• Reduced engine performance caused by inaccurate detonation feedback
• Check engine light concerns tied to knock sensor circuit issues

Installation Notes

• Verify connector style, terminal type, and sensor length before installation.
• Inspect the harness and connector for corrosion or damage before connecting the new sensor.
• Use the vehicle-specific service procedure for torque and mounting location.
• Confirm the application against the exact year, make, and model listed in the fitment data, especially for Chevrolet C1500, Chevrolet K1500, and Pontiac Firebird applications.
