Walker 211-2095 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for OE-Style Cooling System Data

Walker 211-2095 is an engine coolant temperature sensor built to send real-time coolant temperature data to the ECM. That signal helps the engine manage fuel injection, ignition timing, cold start enrichment, and cooling fan operation for stable drivability.

Walker Sensor Only products are focused on the sensor itself, with a direct-fit design that matches factory-style electrical requirements. For drivers and technicians servicing Chevrolet Avalanche 2500, Silverado HD, Suburban 2500, Express 3500, and GMC Sierra HD applications, this part number provides a straightforward replacement path.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• OE-matched resistance values, thermal response, and signal output
• Heat-resistant construction for coolant, vibration, and temperature cycling
• Direct-fit design for factory-style installation
• Sensor Only line focused on the replacement sensor
• 3-pin, female connector with circular connector shape

Product Details

Walker 211-2095 is engineered for accurate coolant temperature reporting so the ECM can make the right adjustments during warm-up and normal operation. This matters on vehicles such as the 2001-2002 Chevrolet Silverado 2500 HD, 2001-2002 GMC Sierra 3500, and 2002 Chevrolet Avalanche 2500, where a stable temperature signal supports consistent engine control. The sensor is built to integrate with factory systems and is intended for direct replacement of the original coolant temperature sensor.

This part cross-references Standard Ignition TX102 for the same application.

What It Helps Address

• Check engine light related to coolant temperature sensor faults
• Incorrect fuel delivery during cold starts
• Unstable idle or drivability concerns tied to temperature input
• Cooling fan operation issues caused by inaccurate temperature data
• Poor fuel economy or elevated emissions from incorrect ECM temperature readings

Installation Notes and Tips

Verify connector style, terminal count, and sensor location before installation. This Walker 211-2095 uses a female circular connector with 3 terminals and no wiring harness included. Confirm the vehicle application against the listed fitment for 1998-1999 Chevrolet P30, 1998-1999 GMC P3500, 2001-2002 Chevrolet Express 3500, 2001-2002 Chevrolet Silverado 3500, 2001-2002 GMC Savana 3500, and related HD and motor home applications.

Quality Assurance

Walker designs this coolant temperature sensor to meet OE specifications for resistance, thermal response, and signal output, supporting reliable communication with the ECM in factory-style systems.
