Engine Coolant Temperature Sensor for Ford and Lincoln

Standard Ignition TX331 is an engine coolant temperature sensor built for direct replacement in select Ford and Lincoln applications. It uses a female oval connector with two male blade terminals and a push-on attachment method for a straightforward OE-style connection.

Key Features

  • Engine coolant temperature sensor for cooling system temperature monitoring
  • Push-on attachment method for secure installation
  • Female oval connector with 1 connector and 2 blade terminals
  • Brass and plastic construction with gold and gray finish
  • 12-volt electrical specification
  • Direct-fit replacement for select Ford F-150, Ford Escape, and Lincoln Corsair applications

Detailed Description

Standard Ignition TX331 is designed for vehicles that rely on accurate coolant temperature input for engine management and gauge operation. This sensor is used in applications such as the 2021-2025 Ford F-150, 2022-2025 Ford Escape, 2021-2025 Lincoln Corsair, and other listed Ford and Lincoln models, including locations on the coolant outlet, radiator hose, and coolant crossover tube. This part cross-references Walker Products 211-2039 for the same application. If you are replacing a Ford F-150 coolant temperature sensor or servicing a Lincoln Corsair coolant outlet sensor, TX331 provides the connector style and terminal layout needed for a proper OE-style match.

What It Is Used For

  • Incorrect coolant temperature readings on the dash or scan tool
  • Engine control issues related to coolant temperature input
  • Cooling fan operation concerns tied to temperature signal data
  • Hard starting or drivability complaints linked to temperature sensor faults
  • Check engine light conditions associated with coolant temperature circuit errors

Installation Notes and Tips

Verify the connector shape, terminal count, and mounting style before installation. Confirm the sensor location on the vehicle, since listed applications place it on the coolant outlet, radiator hose, or coolant crossover tube depending on model and year. Inspect the connector and wiring for corrosion or damage before connecting the new sensor. Always compare the old part number and connector configuration to the replacement part number TX331 before installation.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and engine management components. TX331 is built with brass and plastic materials and is specified for 12-volt systems, supporting consistent replacement fitment for the listed Ford and Lincoln vehicles.
