Detailed Description

Delphi AS10211 is an OE-style knock sensor designed for vehicles that rely on precise detonation monitoring to help the engine control module adjust timing. This sensor supports accurate signal output for Chevrolet Malibu, Chevrolet Cobalt, Chevrolet HHR, Pontiac G5, Pontiac G6, Pontiac Solstice, Saturn Aura, Saturn Sky, Saturn Vue, Saturn Ion, Chevrolet Cavalier, Chevrolet Classic, Pontiac Grand Am, Pontiac Sunfire, Oldsmobile Alero, Saturn L300, Saturn L100, Saturn L200, Saturn LW200, Saturn LS, Saturn LS1, and Saturn LW1 applications. This part cross-references Standard Ignition KS152 for the same application. Delphi AS10211 is built and validated to OE standards to help maintain consistent sensor performance across the listed GM platforms.

What It Helps Address

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

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This sensor uses a screw mount with a rectangular male connector and 2 male terminals, so matching the OE connector and harness layout is important. Confirm vehicle application by year, make, and model before ordering, especially on Chevrolet Malibu, Pontiac Grand Am, and Saturn Vue platforms where multiple engine-management components may be used.

Quality Assurance

Delphi validates its sensors to OE standards and calibrates them for accurate readings. That OE-focused development process helps support dependable signal output and reduces the chance of repeat comebacks after repair.
