Product Details

The TX111 coolant temperature sensor is engineered to monitor engine coolant temperature and send the signal needed by the vehicle’s control system. Standard Ignition states that it controls the manufacturing process from component selection through finished product, and that each sensor is factory tested for operation before it leaves the plant. This part cross-references Four Seasons 37875 for the same application.

Common Symptoms It May Address

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting when the engine is cold
• Rough idle related to inaccurate temperature input
• Cooling fan operation that does not match engine temperature
• Check engine light concerns tied to coolant temperature sensor faults

Installation Notes and Tips

Verify connector shape, terminal count, and attachment style before installation. Inspect the harness connector for corrosion, bent terminals, or damaged locking tabs, and confirm the cooling system is at a safe temperature before removing the old sensor. After installation, clear any stored diagnostic trouble codes and confirm the temperature reading with a scan tool or live data check.

Quality Assurance

Standard Ignition manufactures this sensor with controlled thermistor response values to support accurate temperature measurement and consistent operation. Each TX111 coolant temperature sensor is factory tested to help ensure reliable performance in service.
