Delphi AS10349 Ignition Knock (Detonation) Sensor

Delphi AS10349 Ignition Knock Sensor

Delphi AS10349 is an ignition knock sensor built for OE-style signal accuracy and consistent engine monitoring. It is a direct-fit emission control sensor for select Ford trucks and SUVs, including 1997-1999 Ford E-150 Econoline, Ford E-150 Econoline Club Wagon, Ford Expedition, Ford F-150, and Ford F-250 applications.

Key Features

• OE-calibrated knock sensor for accurate detonation detection
• Delphi sensor design validated to OE standards
• Male connector with 1 connector and 1 terminal
• Wiring harness included for easier vehicle-side connection
• Screw mounting type for secure installation
• Direct replacement for select Ford ignition knock sensor applications

Detailed Description

The Delphi AS10349 ignition knock (detonation) sensor monitors engine vibration patterns and sends a signal to the engine management system so timing can be adjusted when knock is detected. Delphi tests and calibrates its sensors to OE standards, helping maintain accurate readings and reducing repeat repairs. This part cross-references Standard Ignition KS127 for the same application. If you are servicing a 1997-1999 Ford F-150, Ford Expedition, or Ford E-150 Econoline, AS10349 provides the OE-style sensor configuration needed for proper engine control.

What It Helps Address

• Knock sensor fault codes
• Engine pinging or detonation-related drivability issues
• Incorrect ignition timing response from the engine control system
• Rough running caused by inaccurate knock detection
• Check engine light concerns tied to the knock sensor circuit

Installation Notes and Tips

Verify connector style, mounting location, and harness routing before installation. The sensor uses a screw mount, a male connector, and a male terminal configuration. Confirm the vehicle application against the listed fitment for 1997-1999 Ford E-150 Econoline, Ford E-150 Econoline Club Wagon, Ford Expedition, Ford F-150, and Ford F-250 models before replacement. Delphi AS10349 is intended for direct sensor replacement, so clean mounting surfaces and proper torque help support accurate signal transfer.

Quality Assurance

Delphi backs this sensor with OE development and product validation methods, and each sensor is tested and calibrated to OE standards for consistent performance and accurate readings.
