Walker 211-2090 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for GM and Cadillac

Walker 211-2090 is a direct-fit engine coolant temperature sensor built to report real-time coolant temperature to the ECM. It supports fuel delivery, ignition timing, cold-start enrichment, and cooling fan control for accurate engine management.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• OE-style resistance values, thermal response, and signal output
• Blade terminal type with 2 terminals
• Female oblong connector shape for factory-style connection
• Heat-resistant construction for coolant, vibration, and temperature cycling
• Direct-fit design for installation without modifications
• Walker Sensor Only line focuses on the sensor component itself

Detailed Description

Walker Products 211-2090 is engineered for vehicles that rely on precise coolant temperature data to manage engine operation. By sending accurate temperature readings to the ECM, this sensor helps maintain proper fuel injection, ignition timing, cold-start enrichment, and fan operation. The result is stable engine control and consistent system feedback in applications such as the Chevrolet Silverado 1500, GMC Sierra 1500, Cadillac Escalade, and related GM trucks and SUVs.

The Sensor Only product line is centered on the sensing element itself, making it a practical replacement when the original coolant temperature sensor has failed or is triggering a check engine light. This part cross-references VDO 1.830.417 and Bosch 0 280 130 026 for the same application. Part number 211-2090 is built to match factory specifications so it integrates cleanly with OE-style cooling and engine management systems.

Installation Notes and Tips

• Verify the connector shape, terminal count, and mounting location before installation.
• Inspect the coolant passage and connector for corrosion, contamination, or damaged terminals.
• Use the vehicle service procedure for coolant level checks and sensor replacement steps.
• Confirm the ECM clears the fault code after installation and system verification.
