Walker 211-2047 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor Overview

Walker 211-2047 is a sensor-only engine coolant temperature sensor built to send real-time coolant temperature data to the ECM. It supports fuel injection, ignition timing, cold start enrichment, and cooling fan operation for accurate engine management.

Designed for direct-fit service on select Hyundai Elantra, Hyundai Ioniq, and Kia Niro applications, this Walker Sensor Only part number 211-2047 is engineered for OE-style resistance values, thermal response, and signal output.

Key Features

• Pin terminal type with a 2-terminal female connector
• Oblong connector shape for factory-style fitment
• Direct-fit sensor-only design
• Heat-resistant construction for coolant system exposure
• Built to match OE specifications for resistance, response, and output
• No wiring harness included
• No thread sealer included
• No mounting hardware included

Product Details

Walker Products Sensor Only line focuses on replacement sensors that integrate with factory systems without modification. Part number 211-2047 is made for accurate coolant temperature reporting so the ECM can adjust engine operation based on current cooling system conditions. This helps maintain stable drivability in vehicles such as the Hyundai Elantra, Hyundai Ioniq, and Kia Niro.

This part cross-references Standard Ignition TX324 for the same application.

What It Helps Fix

• Check engine light related to coolant temperature sensor faults
• Incorrect coolant temperature readings at the ECM
• Hard cold starts or poor cold-start fuel delivery
• Cooling fan operation issues tied to temperature input
• Fuel economy or drivability problems caused by inaccurate temperature data

Installation Notes

Verify connector shape, terminal count, and thread style before installation. Because no wiring harness or thread sealer is included, reuse or source the required vehicle-specific components as needed. Confirm the sensor location on the engine cooling system before replacing the original unit.
