Detailed Description

The Standard Ignition TX241 coolant temperature sensor monitors engine coolant temperature and sends that information to the vehicle control system. That signal is used by the engine computer and related systems to manage fuel delivery, idle strategy, and temperature-based operation. When the original sensor becomes inaccurate or intermittent, replacement with TX241 can restore a stable temperature reading. This part cross-references Focus Auto Parts 93021 for the same application. For shoppers comparing Ford Focus cooling system sensor options, TX241 is a direct-fit style replacement built around the listed connector and terminal configuration.

What It Helps Address

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting or rough running when the engine is cold
• Cooling fan operation that does not match engine temperature
• Fuel mixture or idle issues tied to temperature signal errors
• Check engine light concerns related to coolant temperature input

Installation Notes and Tips

Verify the connector shape, terminal count, and mounting style before installation. Inspect the harness plug and sealing surfaces for corrosion, damaged terminals, or coolant residue that could affect the new sensor connection. Confirm the replacement matches the vehicle’s original sensor layout before service. For Ford Focus coolant temperature sensor replacement work, compare the old unit to TX241 before final installation.

Quality Assurance

Standard Ignition is a recognized aftermarket brand for electrical and engine management components. TX241 is built to match the listed sensor configuration for service replacement use.
