Detailed Description

Standard Ignition TX102 is engineered for vehicles that rely on precise coolant temperature input for engine control and drivability. The sensor is manufactured with controlled thermistor response values to help maintain measurement accuracy, and each unit is factory tested to verify operation before it leaves the plant. This makes TX102 a practical replacement choice for Chevrolet Express 3500, Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500, GMC Savana 3500, GMC Sierra 2500 HD, GMC Sierra 3500, and other listed GM applications.

For buyers searching by part number, TX102 is also referenced in aftermarket catalogs under related numbers such as Four Seasons 37880 and Focus Auto Parts 93015. If you are replacing a failed coolant temperature sensor on a 2001-2002 Chevrolet Silverado 3500 or a 2001-2002 GMC Sierra 3500, this part matches the listed connector and terminal configuration.

Common Problems It Can Address

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting or rough cold operation caused by faulty temperature input
• Engine control issues tied to inaccurate coolant data
• Cooling fan or fuel strategy problems related to sensor signal errors
• Check engine light concerns associated with coolant temperature sensor faults

Installation Notes and Tips

Confirm the connector shape, terminal count, and mounting style before installation. The TX102 uses a bolt-on design with a round female connector and 3-pin male terminals, so the replacement sensor should match the vehicle harness and mounting point exactly. Inspect the connector for corrosion, damaged pins, or heat-related wear before installing the new sensor.

Quality Assurance

Standard Ignition controls the manufacturing process from component selection through finished product assembly. TX102 is built to tight tolerance specifications and factory tested for operation, supporting consistent performance in the listed Chevrolet and GMC applications.
