Delphi TS10557 Air Charge Temperature Sensor

Air Charge Temperature Sensor for Ford Applications

Delphi TS10557 is an air charge temperature sensor built for Ford, Lincoln, Mazda, and Mercury applications that rely on accurate intake air temperature data for engine management. With OE heritage behind the design, this sensor supports consistent signal output for vehicles such as the Ford F-150, Mustang, Ranger, Taurus, and Explorer.

• Air charge temperature sensor for intake air temperature monitoring
• 2-pin, male terminal design with round connector shape
• Threaded nut mounting for secure installation
• 1-port sensor configuration
• Includes sensor and instruction sheet
• Delphi TS10557 replacement for select Ford, Lincoln, Mazda, and Mercury vehicles

OE-Style Sensor Construction

Delphi TS10557 is engineered from Delphi’s OE experience and aftermarket knowledge, bringing a direct-fit replacement approach to the air charge temperature sensor position. It uses a pin-style terminal layout, male connector and terminal gender, and a threaded nut mount to match the original sensor interface on many Ford-era engine management systems. This part cross-references Standard Ignition AX3 and Walker Products 210-1002 for the same application.

Compatible With 1985-2003 Ford and related applications, this sensor is commonly used on vehicles including the Ford Bronco, E-150 Econoline, F-250, Mustang, Ranger, Taurus, Thunderbird, Lincoln Town Car, and Mercury Sable. The Delphi TS10557 part number is also a useful reference when verifying replacement needs across intake-manifold-mounted and later engine bay configurations.

What This Sensor Helps Address

• Incorrect intake air temperature readings
• Driveability concerns related to air/fuel calculation
• Hard starting or rough running tied to sensor signal errors
• Check engine light conditions related to temperature sensor faults
• Replacement needs for worn, damaged, or corroded original sensors

Installation Notes and Tips

Confirm connector shape, terminal count, and mounting style before installation. Delphi TS10557 is a threaded-nut sensor with a round, 2-terminal male connection, so matching the original electrical connector and mounting location is important. Review the included instruction sheet and verify the vehicle’s emissions configuration and engine layout, especially on 1995 Ford applications with California or Massachusetts emission notes.

Quality Assurance

Delphi draws on more than a century of OE experience and supplier knowledge used by major automakers. That background is reflected in the design and application matching of TS10557, helping support dependable replacement selection for air charge temperature sensor service.
