Walker 211-2084 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for GM Applications

Walker 211-2084 is an engine coolant temperature sensor built to send real-time coolant temperature data to the ECM. That signal supports fuel delivery, ignition timing, cold-start enrichment, and cooling fan operation on applications such as the Chevrolet Silverado 1500 and GMC Sierra 1500.

Walker Products Sensor Only line focuses on direct replacement sensors that match OE-style electrical behavior and factory integration requirements. Part number 211-2084 is built for a direct-fit installation on the engine block or engine location shown in the fitment data.

Key Features

• Blade terminal type with a 2-terminal layout
• Oblong female connector for factory-style connection
• No wiring harness included
• OE-matched resistance values, thermal response, and signal output
• Heat-resistant construction for coolant, vibration, and temperature cycling
• Direct-fit design for replacement service

Detailed Description

This Walker engine coolant temperature sensor monitors coolant temperature and reports that data to the ECM so the engine can adjust operating strategy in real time. Accurate temperature input helps maintain proper fuel injection, ignition timing, cold-start operation, and fan control. For technicians servicing a check engine light or replacing a failed sensor, Walker 211-2084 provides a factory-style replacement built around OE specifications.

Compatible With 2020-2023 Cadillac CT4, engine location; 2023 Chevrolet Colorado, engine block; 2019-2023 Chevrolet Silverado 1500, engine block; 2023 GMC Canyon, engine block; 2019-2023 GMC Sierra 1500, engine block; 2022 Chevrolet Silverado 1500 LTD, engine block; and 2022 GMC Sierra 1500 Limited, engine block. This part cross-references GM OE 12673064 for the same application.

What It Helps Address

• Incorrect coolant temperature readings
• Check engine light related to coolant temperature sensor faults
• Hard cold starts or poor cold-start fuel control
• Cooling fan operation concerns tied to temperature input
• Rough engine performance caused by inaccurate ECM temperature data

Installation Notes and Tips

Verify the connector shape, terminal count, and sensor location before installation. This sensor uses a blade terminal, oblong female connector, and no wiring harness, so the factory connector must match. Confirm the engine-block or engine-mounted location listed for your vehicle before replacing the original part.

Quality Assurance

Walker Products engineers this sensor to match OE resistance values, thermal response, and signal output for reliable factory-system integration. The heat-resistant design is built for continuous exposure to coolant, vibration, and wide temperature swings.
