Delphi AS10373 Knock Sensor OE Replacement

The Delphi AS10373 is an OE-quality knock sensor engineered to detect engine detonation and pre-ignition events. By monitoring vibration frequencies produced during abnormal combustion, the sensor sends a signal to the engine control module (ECM), which then adjusts ignition timing to prevent engine damage and restore optimal performance.

Delphi is a Tier 1 OEM supplier with decades of experience manufacturing sensors to original equipment standards, ensuring this knock sensor meets or exceeds the fit, form, and function of the factory part it replaces.

Key Features:

• OE-matching design for direct, no-modification installation
• Engineered to original equipment specifications for reliable signal accuracy
• Constructed with high-quality piezoelectric sensing element for consistent detonation detection
• Resists heat, vibration, and engine fluids for long service life
• Helps restore proper ignition timing correction and protect engine internals
• Connector and mounting hardware compatible with original factory location

A faulty knock sensor can trigger a Check Engine light, reduce fuel economy, cause sluggish acceleration, and over time lead to serious engine damage. Replacing a failed sensor with the Delphi AS10373 restores the ECM's ability to protect and optimize your engine under all driving conditions.
