Walker 211-2181 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Hyundai Tucson

Walker 211-2181 is a direct-fit engine coolant temperature sensor built for accurate temperature feedback to the ECM. It supports fuel delivery, ignition timing, cold-start enrichment, and cooling fan control on 2015-2017 Hyundai Tucson applications.

Key Features

• Blade terminal type with a 2-terminal female rectangle connector
• OE-style resistance values, thermal response, and signal output
• Heat-resistant construction for exposure to coolant, vibration, and temperature swings
• Direct-fit design for factory-style replacement
• Sensor only; wiring harness not included

Product Details

Walker Products Sensor Only line focuses on replacement sensors that match factory electrical behavior and connector style. Part number 211-2181 is engineered for reliable coolant temperature readings so the ECM can manage engine operation accurately. This part cross-references Standard Ignition TX321 for the same application.

Compatible With 2015-2017 Hyundai Tucson, N/A. Use Walker 211-2181 when replacing a failed coolant temperature sensor on a Hyundai Tucson with a 2-terminal blade connection and rectangle female plug. The part number 211-2181 is also a useful reference when verifying the correct sensor against existing service information.

Common Issues This Sensor May Address

• Check engine light related to coolant temperature signal faults
• Hard cold starts or extended warm-up behavior
• Incorrect fuel mixture caused by inaccurate temperature input
• Cooling fan operation that does not match engine temperature
• Poor fuel economy from incorrect ECM temperature data

Installation Notes

Confirm connector shape, terminal count, and sensor location before installation. Inspect the cooling system connector and wiring for corrosion or damage, and verify the cooling system is at the proper level before replacing the sensor. Because this is a sensor-only part, reuse the existing harness connection.

Quality Assurance

Walker Products builds this sensor to OE specifications for resistance, thermal response, and output signal consistency. The design uses durable, heat-resistant materials to handle continuous coolant exposure and engine bay temperature changes.
