Delphi AS10009 ignition knock (detonation) sensor for the 2005-2009 Buick LaCrosse V6 3.8L and other vehicles senses engine knock and sends a signal to the engine control module. It is tested and calibrated to OE standards for accurate readings.
- Helps maximize engine performance with all fuels
- Helps guard against engine damage from pre-ignition knocking
- Calibrated for a wide variety of frequencies to detect shifts and give accurate signals
- Sealed to withstand humidity, salt spray and automotive fluids
- Ground isolated design with a 2-wire shielded harness that helps protect the signal from electromagnetic interference (EMI)
- Self-generating piezoelectric design that needs no power to the sensor
Quick facts
- Part: Delphi AS10009 ignition knock (detonation) sensor
- Fits: 2005-2009 Buick LaCrosse V6 3.8L and other vehicles
- Condition: New
A check engine light, pinging under load or a loss of power can mean the knock sensor is worn, though a damaged wiring harness or a fouled spark plug can be behind them too, so trace the cause before you replace the sensor.
