Walker 211-2042 Engine Coolant Temperature Sensor - Lower

Engine Coolant Temperature Sensor Overview

Walker 211-2042 is an engine coolant temperature sensor built to report real-time coolant temperature to the ECM. That signal helps the engine manage fuel delivery, ignition timing, cold-start enrichment, and cooling fan operation for accurate control in Hyundai, Kia, and Genesis applications.

Walker Sensor Only products focus on OE-style signal accuracy and direct-fit replacement. Part number 211-2042 is engineered for factory-style resistance values, thermal response, and output so it integrates cleanly with the vehicle’s original engine management system.

Key Features

• Blade terminal type with 2 terminals for factory-style electrical connection
• Female oblong connector shape for direct replacement fitment
• Heat-resistant construction for constant coolant exposure and temperature cycling
• OE-matched resistance values and signal output for ECM communication
• Direct-fit design with no wiring harness included
• No mounting hardware or thread sealer included

Detailed Product Description

This engine coolant temperature sensor is designed to provide the ECM with accurate temperature data from the cooling system. On vehicles such as the Hyundai Elantra, Hyundai Sonata, Kia Sorento, and Genesis G80, that information is used to adjust engine operation as temperatures change. Walker 211-2042 is built for dependable signal delivery in applications where precise coolant temperature readings matter for drivability and emissions control.

The Walker Sensor Only line is focused on replacement sensors that match OE specifications for resistance, thermal response, and output characteristics. That makes 211-2042 a practical choice when replacing a failed sensor or diagnosing a check engine light related to coolant temperature input. This part cross-references Standard Ignition TX337 for the same application.

What This Sensor Helps Address

• Incorrect coolant temperature readings sent to the ECM
• Check engine lights tied to coolant temperature sensor faults
• Hard cold starts or poor cold-start fuel enrichment
• Cooling fan operation issues caused by inaccurate temperature input
• Fuel economy and drivability problems related to temperature signal errors

Installation Notes and Tips

Verify connector shape, terminal count, and mounting location before installation. This sensor uses a blade terminal design with a female oblong connector and does not include a wiring harness, mounting hardware, or thread sealer. Confirm the engine block or charge air cooling location listed for your vehicle before replacing the original sensor.
