Delphi AS10261 ignition knock (detonation) sensor for the 2007-2013 Chevrolet Silverado 1500 V8 4.8L, 5.3L or 6.0L, the 2009-2013 Silverado 1500 V8 6.2L and other vehicles listens for engine knock and sends a signal to the engine control module. The module uses that signal to help it respond to knock.
- Self-generating piezoelectric design that needs no power to the sensor
- Sealed against humidity, salt spray and automotive fluids
- Ground-isolated design with a 2-wire shielded harness to help protect the signal from electromagnetic interference (EMI)
- Calibrated for a wide variety of frequencies to detect shifts and give accurate signals
- Helps guard against engine damage from pre-ignition knocking
Quick facts
- Part: Delphi AS10261 ignition knock (detonation) sensor
- Fits: the 2007-2013 Chevrolet Silverado 1500 V8 4.8L, 5.3L or 6.0L, the 2009-2013 Silverado 1500 V8 6.2L and other vehicles
A failing sensor can show up as a check engine light, pinging or rattling under load, or weaker power. These signs alone do not prove the sensor is the problem; poor-quality fuel is another common cause of pinging.

Frequently Asked Questions
Does the Delphi AS10261 knock sensor fit a 2007-2013 GMC Sierra 1500 V8 6.2L?
Yes, Delphi AS10261 fits the 2007-2013 GMC Sierra 1500 V8 6.2L. If your truck or SUV is a different one, look up its year and engine in the "Vehicles it fits" section to see whether it is covered.
What is in the package with the Delphi AS10261 knock sensor?
The package holds one ignition knock (detonation) sensor.
Does the Delphi AS10261 knock sensor need its own power supply?
No. Delphi AS10261 has a self-generating piezoelectric design that requires no power to the sensor. Its 2-wire shielded harness is ground isolated to help protect the signal from EMI.
What can a failing knock sensor look like while driving?
A check engine light, pinging or rattling under load and reduced engine power can come with a failing knock sensor. A shop can test the sensor, since the test needs the engine running.
Can this knock sensor handle road salt and engine fluids?
Yes. The sensor is sealed to withstand humidity, salt spray and automotive fluids.
