Ignition Knock (Detonation) Sensor for 2015-2025 Ford F-150 & More - Delphi AS10326

Delphi AS10326 sensor for the 2015-2025 Ford F-150 2.7L and other vehicles is an ignition knock (detonation) sensor that picks up engine knock and sends a signal.

• This Delphi knock sensor helps maximize engine performance with all fuels.
• It helps protect the engine from damage caused by pre-ignition knocking.
• Tested and calibrated to OE standards, for a wide variety of frequencies, to detect shifts and send accurate signals.
• Sealed to withstand humidity, salt spray and automotive fluids.
• The ground isolated design with a 2 wire shielded harness helps protect the sensor signal from electro magnetic interference (EMI).
• The self generating piezoelectric design requires no power to the sensor.

A check engine light, engine pinging or reduced power can mean the knock sensor is worn, though a damaged wiring harness or worn spark plugs can produce the same signs, so find the cause before you replace it.

The 2017-2019 Ford Fusion 2.7L and the 2024-2025 Ford Ranger 2.7L / 3.0L also fit this sensor, along with more Ford and Lincoln models, and each takes one. Open the "Vehicles it fits" section to check your exact model and engine.
