Walker 211-2080 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for OE-Style Cooling System Data

Walker 211-2080 is an engine coolant temperature sensor built to send real-time coolant temperature data to the engine control module (ECM). For 2015 Audi A3 and 2015 Volkswagen Beetle, Golf, Jetta, and Passat applications, this sensor supports accurate fuel delivery, ignition timing, cold start enrichment, and cooling fan operation.

Sensor Only Line Details

Walker’s Sensor Only line focuses on direct replacement sensors without extra harness components. This Walker Products engine coolant temperature sensor is engineered to match OE resistance values, thermal response, and signal output for factory-style communication with the vehicle’s control system.

• Part number: 211-2080
• Terminal type: Blade
• Terminal quantity: 2
• Connector shape: Oblong
• Connector gender: Female
• Wiring harness included: No
• Direct-fit replacement for factory coolant temperature sensor locations

Detailed Product Overview

Walker 211-2080 is designed for vehicles that rely on precise coolant temperature input to manage engine operation and emissions control. By delivering accurate temperature readings from the cooling system, the sensor helps the ECM adjust cold-start fueling, ignition timing, and radiator fan strategy. This makes it a practical replacement for a failed sensor on 2015 Audi A3 and 2015 Volkswagen Beetle, Golf, Jetta, and Passat models. This part cross-references Standard Ignition TX282 and Dorman - HELP 82421 for the same application.

Common Issues This Sensor Can Address

• Check engine light related to coolant temperature signal faults
• Hard starting or rough running during cold starts
• Incorrect fuel mixture caused by inaccurate temperature input
• Cooling fan operation problems tied to sensor signal errors
• Poor drivability when the ECM receives unstable coolant temperature data

Installation Notes and Fitment

Fits 2015 Audi A3, location-engine; sensor only. Fits 2015 Volkswagen Beetle, sensor only. Fits 2015 Volkswagen Golf, location-engine; sensor only. Fits 2015 Volkswagen Jetta, sensor only. Fits 2015 Volkswagen Passat, sensor only.

Before installation, confirm the connector style matches the vehicle harness: blade terminals, 2 terminals, oblong female connector. Because no wiring harness is included, reuse the existing harness connection where applicable and inspect the connector for corrosion, heat damage, or loose terminals before installing the new sensor.

Quality Assurance

Walker Products engineers this coolant temperature sensor to OE specifications for resistance, thermal response, and signal output, using heat-resistant materials built for constant exposure to coolant, vibration, and temperature swings. That specification-focused approach supports reliable integration with factory engine management systems.
