Delphi AS10238 Knock Sensor OE Replacement

The Delphi AS10238 is an OE-quality replacement knock sensor designed to restore proper engine management function. The knock sensor monitors engine vibration frequencies associated with detonation (knock or ping), sending a voltage signal to the engine control module (ECM) so ignition timing can be retarded to protect the engine from damage.

Key Features:

• OE form, fit, and function replacement for a direct, no-modification installation
• Manufactured to Delphi's original equipment standards for reliable, long-term performance
• Detects abnormal combustion (engine knock/detonation) to protect internal engine components
• Enables the ECM to optimize ignition timing under varying load and fuel conditions
• Constructed with a piezoelectric sensing element for accurate vibration signal output
• Corrosion-resistant housing suitable for harsh underhood environments

Delphi is a trusted OE supplier with decades of experience producing engine management sensors for leading automakers worldwide. The AS10238 is engineered to meet or exceed original equipment specifications, making it a reliable choice for restoring proper knock detection and protecting engine longevity.
