Walker 211-2130 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Audi

Walker 211-2130 is a sensor-only engine coolant temperature sensor built to report cooling-system temperature data to the ECM in real time. For Audi R8 and Audi Q7 applications, accurate coolant temperature input supports fuel delivery, ignition timing, cold-start enrichment, and radiator fan control.

Walker Products Sensor Only line focuses on direct replacement sensors that match OE-style resistance values, thermal response, and signal output for factory integration.

Key Features

• Engine coolant temperature sensor for ECM temperature monitoring
• Blade terminal type with 2 terminals
• Female circular connector for factory-style connection
• Direct-fit sensor-only design; wiring harness not included
• Heat-resistant construction for constant coolant exposure and vibration
• OE-style resistance values and signal output

Detailed Description

Walker 211-2130 is engineered for vehicles that rely on precise coolant temperature feedback to manage engine operation. It helps the ECM adjust fuel injection, ignition timing, cold-start enrichment, and cooling fan operation based on live temperature data. This makes it a practical replacement for a failed coolant temp sensor on Audi R8 and Audi Q7 models where accurate temperature reporting is critical to drivability and emissions control.

This part cross-references Standard Ignition TX182 for the same application. If you are replacing a sensor on a 2010-2023 Audi R8 or a 2011-2012 Audi Q7, Walker 211-2130 provides a direct-fit, sensor-only solution designed to integrate with factory systems.

What It Helps Solve

• Check engine light related to coolant temperature signal faults
• Hard starting or rough cold starts
• Incorrect fuel mixture caused by inaccurate temperature input
• Cooling fan operation that does not match engine temperature
• Poor fuel economy or elevated emissions from faulty temperature data

Installation Notes and Tips

Verify the connector shape, blade terminal count, and female connector style before installation. This sensor uses a circular connector and does not include a wiring harness. Confirm the vehicle application by year and model: Fits 2010-2012 Audi R8, N/A; Fits 2014-2015 Audi R8, N/A; Fits 2017-2018 Audi R8, N/A; Fits 2020-2023 Audi R8, N/A; Fits 2011-2012 Audi Q7, N/A, Location-Cylinder Head; Sensor Only.

Quality Assurance

Walker Products designs this Sensor Only coolant temperature sensor to match OE specifications for resistance, thermal response, and signal output, supporting reliable factory-system operation on Audi R8 and Audi Q7 applications.
