Walker 211-2030 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for OE-Style Cooling System Data

Walker 211-2030 is an engine coolant temperature sensor built to send real-time coolant temperature data to the engine control module. That signal is used for fuel delivery, ignition timing, cold start enrichment, and cooling fan operation, helping the system respond accurately as temperatures change.

Compatible With 2017-2020 Toyota 86, 2014-2016 Scion FR-S, and 2014 Subaru XV Crosstrek, this Sensor Only replacement is built for direct-fit service on the listed applications. Walker 211-2030 is a practical choice when diagnosing a coolant temperature fault, drivability concern, or check engine light tied to temperature input.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• Blade terminal type with a square connector shape
• 2-terminal female connector design
• No wiring harness included
• Engineered to match OE resistance values, thermal response, and signal output
• Heat-resistant construction for exposure to coolant, vibration, and temperature swings
• Direct-fit replacement for listed Toyota, Scion, and Subaru applications

Product Details

Walker Sensor Only line focuses on replacement sensors that integrate with factory engine management systems. This part number, 211-2030, is built to provide consistent coolant temperature feedback so the ECM can adjust operating strategy based on actual engine temperature. Accurate sensor output supports stable cold starts, proper fan control, and correct fuel and ignition decisions.

This part cross-references Standard Ignition TX238 and NTK EF0077 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 operation
• Incorrect radiator fan activation
• Fuel mixture or ignition timing concerns caused by inaccurate temperature input
• Temperature gauge or ECM data inconsistencies on the listed vehicles

Installation Notes and Tips

Verify connector style, terminal count, and sensor location before installation. This Walker 211-2030 sensor uses a square female connector with blade terminals and does not include a wiring harness. Inspect the cooling system for leaks, corrosion, or damaged connectors before replacing the sensor, and confirm the engine is cool before service.

Fits 2017-2020 Toyota 86, Sensor Only. Fits 2014-2016 Scion FR-S, Sensor Only. Fits 2014 Subaru XV Crosstrek, Sensor Only.
