Walker 211-2138 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Genesis and Kia

Walker 211-2138 is a direct-fit engine coolant temperature sensor that reports cooling system temperature to the ECM in real time. It is built for accurate signal output, stable resistance values, and reliable thermal response in OE-style applications.

Compatible With 2021-2024 Genesis G80, 2023-2024 Genesis G90, 2022-2024 Genesis GV70, 2021-2024 Genesis GV80, and 2022-2023 Kia Carnival, this Sensor Only part is a practical replacement when the original coolant temperature reading becomes inaccurate. Walker Products 211-2138 is engineered for factory-style integration on Genesis and Kia applications.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• OE-matched resistance values, thermal response, and signal output
• Direct-fit design for factory-style replacement
• Durable, heat-resistant construction for coolant and vibration exposure
• 2-terminal pin design with female oblong connector
• No mounting hardware, wiring harness, or thread sealer included

Detailed Description

Walker Products 211-2138 is part of the Sensor Only line, focused on replacement sensors that match original equipment specifications without unnecessary extras. This engine coolant temperature sensor helps the ECM manage fuel injection, ignition timing, cold start enrichment, and cooling fan operation by sending accurate temperature data from the cooling system. For drivers and technicians servicing a Genesis G80, Genesis GV80, or Kia Carnival, the correct coolant temperature signal is important for consistent drivability and emissions control.

This part cross-references 392203N030 for the same application.

What It Helps Address

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

Installation Notes and Tips

Verify connector shape, terminal count, and thread style before installation. This sensor uses a 2-pin female oblong connector and does not include mounting hardware, a wiring harness, or thread sealer. Confirm the vehicle application by year, make, and model before replacing the original unit on Genesis G80, Genesis GV70, Genesis GV80, Genesis G90, or Kia Carnival models.

Quality Assurance

Walker Products designs this coolant temperature sensor to meet OE specifications for resistance, thermal response, and output characteristics, supporting reliable integration with factory engine management systems.
