Key Features

• Ignition knock (detonation) sensor for emission control and engine management systems
• OE heritage and application knowledge built into the aftermarket part
• Pin terminal type with a square, female connector
• 2-terminal, bolt-on mounting design
• Package includes the sensor and instruction sheet
• Delphi AS10278 cross-references Standard Ignition KS377 for the same application

Detailed Description

Delphi AS10278 is an ignition knock sensor engineered for Ford trucks and performance applications that rely on precise knock detection. It fits 2010-2017 Ford F-150, 2011-2023 Ford F-250 Super Duty, 2011-2023 Ford F-350 Super Duty, 2011-2022 Ford Mustang, 2017-2019 Ford E-350 Super Duty, and 2021-2023 Ford E-350 Super Duty. The sensor uses a bolt-on mounting style, a square female connector, and male pin terminals for a direct-fit electrical interface. Delphi’s OE background supports the kind of signal accuracy needed for proper ignition timing control and engine protection. If you are replacing a Ford F-150 knock sensor or servicing a Ford Mustang detonation sensor, AS10278 provides a fitment-focused replacement option.

What It Helps Address

• Knock sensor fault codes related to detonation detection
• Rough running caused by incorrect ignition timing response
• Reduced engine performance from inaccurate knock feedback
• Check engine lights tied to the knock sensor circuit
• Service replacement for worn or damaged Ford knock sensors

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This sensor uses a bolt-on design and does not include mounting hardware. Confirm the vehicle’s original connector and sensor location match the application before replacing the part. For Ford F-250 Super Duty, Ford F-350 Super Duty, and Ford Mustang service work, compare the old sensor to the Delphi AS10278 before final assembly.

Quality Assurance

Delphi draws on 100 years of OE experience and supplier knowledge from top automakers, with aftermarket parts built around original equipment engineering standards. The AS10278 is produced with that OE heritage in mind for dependable fit and signal performance.
