Delphi AS10278 ignition knock (detonation) sensor for the 2010-2014 Ford F-150 V8 6.2L, the 2011-2017 F-150 V8 5.0L and other vehicles senses engine knock and sends a signal to the engine computer. The computer uses that signal to respond to knock.
- Knock sensor helps maximize engine performance with all fuels
- Helps protect the engine from damage caused by 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 helps protect the signal from electromagnetic interference (EMI)
- Self-generating piezoelectric design needs no power to the sensor
Quick facts
- Part: Delphi AS10278 ignition knock (detonation) sensor
- Fits: the 2010-2014 Ford F-150 V8 6.2L, the 2011-2017 F-150 V8 5.0L and other vehicles
- Condition: New
A failing knock sensor can show up as a check engine light, a pinging or rattling noise under load, or less power. Worn spark plugs, damaged wiring or a poor fuel choice can be behind these signs as well, so track down the cause before you buy a sensor.

Frequently Asked Questions
Does the Delphi AS10278 knock sensor fit a 2011-2022 Ford Mustang V8 5.0L?
Yes. Delphi AS10278 fits the 2011-2022 Ford Mustang V8 5.0L. The 2011-2014 models take two sensors and the 2015-2022 models take one.
Does a Delphi knock sensor need external power to work?
No. Delphi AS10278 is a self-generating piezoelectric sensor that requires no power to the sensor. It has a 2-wire shielded, ground-isolated harness.
Is this knock sensor sealed against road salt and engine fluids?
Yes. This knock sensor is sealed to withstand humidity, salt spray and automotive fluids.
What can a failing knock sensor look like when driving?
A check engine light, a pinging or rattling noise under load or a drop in power can mean a failing knock sensor. A shop can test the sensor and its circuit.
Does Delphi AS10278 replace part number AL3Z 12A699-BA?
Yes. AL3Z 12A699-BA is one of the numbers this Delphi AS10278 knock sensor replaces.
