Detailed Description

Delphi AS10051 is an emission control sensor designed to monitor engine knock and send the signal needed for ignition timing adjustments. Delphi draws on OE experience and supplier knowledge used by major automakers, which is reflected in the sensor’s fit, connector design, and application-focused construction.

What It Helps Address

• Knocking or pinging caused by incorrect ignition timing
• Check engine light related to knock sensor circuit faults
• Reduced engine performance from inaccurate detonation feedback
• Unstable combustion control under load or acceleration
• Driveability issues tied to a failing ignition knock sensor

Installation Notes and Tips

Verify connector shape, connector gender, and mounting style before installation. The AS10051 uses a threaded nut mount and a single oval female connector, so matching the original sensor connection is important for proper fitment. Review the included instruction sheet and confirm the vehicle application before service.
