Delphi AS10312 Knock Sensor

The Delphi AS10312 Knock Sensor is an OE-quality ignition knock detection sensor designed to maximize engine performance and protect against damage from pre-ignition detonation. This sensor uses piezoelectric technology to detect vibrations caused by abnormal combustion and send precise signals to the engine control module for timing adjustments.

Key Features:

• Piezoelectric sensing element generates voltage signals based on engine vibrations
• Calibrated to detect knock frequencies across a wide range of operating conditions
• Ground-isolated design with shielded harness protects against electromagnetic interference
• Self-generating design requires no external power source
• Manufactured to meet or exceed OEM specifications
• Helps optimize ignition timing for improved fuel economy and performance
• Prevents potential engine damage from detonation and knock

Delphi knock sensors deliver reliable performance with all fuel grades by continuously monitoring engine vibrations and providing accurate feedback to the ECU. When knock is detected, the sensor signals the computer to retard ignition timing, eliminating harmful detonation that can damage pistons, valves, and other internal engine components.
