Walker 211-2071 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Mini

Walker 211-2071 is a sensor-only engine coolant temperature sensor that sends real-time coolant temperature data to the ECM. That signal supports fuel delivery, ignition timing, cold-start enrichment, and cooling fan operation for accurate engine management.

Sensor-Only Design

The Walker Sensor Only line focuses on direct replacement sensors built to OE-style resistance values, thermal response, and signal output. This helps maintain factory communication between the cooling system and the engine control module on Mini Cooper, Mini Cooper Countryman, and Mini Cooper Paceman applications.

• Terminal type: Pin
• Connector shape: Oblong
• Terminal quantity: 2
• Connector gender: Female
• Direct-fit replacement for factory-style installation
• Heat-resistant construction for coolant and temperature cycling exposure

Detailed Product Overview

Walker 211-2071 is an engine coolant temperature sensor for vehicles that rely on precise coolant temperature input to manage drivability and emissions. Compatible With 2011-2015 Mini Cooper, 2011-2016 Mini Cooper Countryman, and 2013-2016 Mini Cooper Paceman, this sensor helps the ECM interpret engine temperature changes during warm-up, normal operation, and fan control events. This part cross-references Four Seasons 58595 for the same application.

Common Issues This Sensor Can Address

• Incorrect coolant temperature readings sent to the ECM
• Check engine light related to temperature sensor performance
• Hard cold starts or extended warm-up behavior
• Cooling fan operation that does not match engine temperature
• Fuel mixture and ignition timing concerns tied to temperature input

Installation Notes and Tips

Verify the connector style, terminal count, and oblong female plug before installation. The sensor uses a pin terminal layout and does not include a wiring harness. Confirm the vehicle application by year and model before replacing the original coolant temperature sensor.

Quality Assurance

Walker Products engineers this sensor to match OE specifications for resistance, thermal response, and signal output, with durable materials selected for constant coolant exposure, vibration, and repeated temperature swings.
