Delphi AS10273 ignition knock (detonation) sensor for the 2014-2021 Chevrolet Silverado 1500 V6 4.3L, the 2014-2026 Silverado 1500 V8 5.3L or 6.2L and other vehicles picks up engine knock and sends out a signal. It helps guard the engine against damage from pre-ignition knocking.
- Knock detection that helps maximize engine performance with all fuels
- 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 helps protect the signal from electromagnetic interference (EMI)
- Self-generating piezoelectric design requires no power to the sensor
Quick facts
- Part: Delphi AS10273 ignition knock (detonation) sensor
- Fits: 2014-2021 Chevrolet Silverado 1500 V6 4.3L, the 2014-2026 Silverado 1500 V8 5.3L or 6.2L and other vehicles
- Condition: New
A lit check engine light or pinging under load can mean a knock sensor is failing, though wiring and other engine faults can show up the same way. With the engine off and cool, look over the sensor's harness and connector for cracks, corrosion or chafing before you replace anything. A shop can test the signal itself.
