Delphi TS10338 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Ford and Mercury

The Delphi TS10338 engine coolant temperature sensor provides direct temperature feedback to the engine management system for accurate fuel and ignition control. It is a fitment-based replacement for select Ford, Mercury, and Lincoln vehicles, including Ford Fusion, Mercury Milan, Ford Escape, Mercury Mariner, Lincoln Zephyr, Ford Taurus, and Mercury Sable applications.

Key Features

• Engine coolant temperature sensor for OE-style temperature signal input
• Pin terminal design with 1 female connector and 2 male terminals
• Rectangle connector shape for the listed applications
• Push-on mounting type for direct replacement use
• Package contents include the engine coolant temperature sensor and instruction sheet
• Delphi part number TS10338

Detailed Description

Delphi TS10338 is an engine coolant temperature sensor built for vehicles that rely on precise coolant temperature data to manage engine operation. Delphi draws on OE experience and supplier knowledge developed over decades of original equipment service, and that background is reflected in the design of this aftermarket sensor. This part cross-references Standard Ignition TX139 for the same application. It is a direct-fit option for 2006-2009 Ford Fusion, 2006-2009 Mercury Milan, 2001-2008 Ford Escape, 2005-2008 Mercury Mariner, 2006 Lincoln Zephyr, 2003-2005 Ford Taurus, and 2003-2005 Mercury Sable models.

What It Helps Address

• Incorrect coolant temperature readings at the engine control system
• Hard starting or rough running related to temperature signal errors
• Fuel mixture issues caused by inaccurate coolant data
• Illuminated check engine light tied to sensor faults
• Poor drivability when the engine computer receives inconsistent temperature input

Installation Notes and Tips

Confirm connector style, terminal count, and mounting type before installation. The Delphi TS10338 uses a single rectangular female connector with two male terminals and a push-on mount, so matching the original sensor configuration is important. Inspect the connector and wiring for corrosion or damage before fitting the new sensor, and follow the included instruction sheet during replacement. Verify the application by year, make, and model before ordering, especially on Ford Escape, Mercury Mariner, and Ford Taurus fitments.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and technical knowledge developed through long-term service to major automakers. The TS10338 is engineered to meet the needs of the listed Ford, Mercury, and Lincoln applications with the same type of temperature-signal function expected from an engine coolant temperature sensor.
