Walker 211-2022 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for GM Applications

Walker 211-2022 is an engine coolant temperature sensor built to deliver real-time coolant temperature data to the ECM. Accurate temperature input supports fuel injection, ignition timing, cold-start enrichment, and cooling fan operation across a wide range of GM vehicles, including Chevrolet Malibu, Chevrolet Colorado, and GMC Canyon applications.

Walker Sensor Only products focus on the sensor itself for direct replacement service. Part number 211-2022 is engineered to match OE resistance values, thermal response, and signal output for reliable communication with factory engine management systems.

Key Features

• Engine coolant temperature sensor for ECM temperature monitoring
• Direct-fit replacement for select Cadillac, Chevrolet, Buick, and GMC vehicles
• 2-pin terminal design with female circle connector
• Heat-resistant construction for continuous exposure to coolant and temperature swings
• Built to match OE-style resistance, response, and signal characteristics
• Wiring harness not included

Detailed Description

The Walker Sensor Only line is focused on replacement sensors that integrate with factory systems without modification. This engine coolant temperature sensor helps the ECM read coolant temperature accurately so the engine can adjust fueling, timing, idle behavior, and fan control. The result is dependable temperature reporting for everyday drivability and emissions management. Walker 211-2022 is a direct replacement for many 2013-2023 GM platforms, including Chevrolet Camaro, Chevrolet Malibu, GMC Acadia, and Cadillac CT4 applications.

This part cross-references Standard Ignition TX268 for the same application.

What It Is Used For

• Check engine light related to coolant temperature sensor faults
• Incorrect coolant temperature readings at the ECM
• Hard cold starts or extended warm-up behavior
• Cooling fan operation concerns tied to temperature input
• Fueling or ignition timing issues caused by inaccurate temperature data

Installation Notes and Tips

• Verify the connector style before installation: 2 terminals, female circle connector.
• Inspect the O-ring and sealing surface on applications that use an included O-ring.
• Confirm the sensor location on water outlet applications before removal.
• Clear diagnostic trouble codes after installation and recheck live coolant temperature data.
• Use the vehicle-specific fitment list to confirm the exact year, make, and model.

Quality Assurance

Walker Products engineers these coolant temperature sensors to OE specifications for resistance, thermal response, and signal output. Durable materials are used to withstand coolant exposure, vibration, and repeated heat cycling in normal engine operation.
