Detailed Description

The Standard Ignition TX104 coolant temperature sensor is engineered to report engine coolant temperature accurately so the vehicle control system can manage fueling, idle quality, and cooling strategy. Standard Ignition controls the manufacturing process from component selection through final assembly, and each sensor is factory tested before release. This part is a strong match for Ford Focus, Ford Fusion, Ford Escape, Ford Explorer, and related applications that use the specified connector and terminal layout. This part cross-references Delphi TS10329 and Gates 12065 for the same application.

Compatible With 1999-2021 Ford, Mazda, Mercury, Jaguar, Lincoln, and Land Rover applications listed in the fitment data, including many Ford Focus and Ford Fusion configurations. Standard Ignition TX104 is also referenced in service catalogs for select Mazda B-Series trucks and Ford Ranger applications where the connector style and sensor location match.

Common Problems This Sensor Can Address

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting, rough idle, or poor cold-engine fuel control
• Cooling fan operation that does not follow engine temperature correctly
• Check engine light concerns related to coolant temperature sensor circuits
• Driveability issues caused by inaccurate engine temperature input

Installation Notes and Tips

• Verify connector shape, terminal count, and attachment style before installation.
• Check the vehicle-specific location, as fitment notes include radiator, intake manifold, thermostat housing, and water outlet placements.
• Confirm the exact application for Ford Focus, Ford Fusion, and Ford Ranger models with alternate-number or push-in notes.
• Inspect the connector and wiring for corrosion or damage before installing the new sensor.

Quality Assurance

Standard Ignition states that its coolant temperature sensors are 100% factory tested and built under controlled manufacturing processes to support accurate operation. TX104 is backed by the brand’s broad sensor coverage and production standards for service-professional use.
