Walker 211-2146 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor Overview

Walker Products 211-2146 is an engine coolant temperature sensor built to deliver real-time coolant temperature data to the ECM. With accurate signal output and OE-style resistance values, it supports correct fuel delivery, ignition timing, cold start enrichment, and cooling fan operation.

Walker Sensor Only components are focused on direct replacement fitment for factory systems. This 211-2146 sensor is engineered for reliable integration on select Genesis, Hyundai, and Kia applications, including water pump and engine cooling locations.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• OE-matched resistance values, thermal response, and signal output
• Durable, heat-resistant construction for coolant and vibration exposure
• Direct-fit design for factory-style installation
• Connector shape: oblong
• Terminal type: pin
• 2 terminals, female connector, male terminals

Detailed Product Description

Walker 211-2146 is designed to replace a failed coolant temperature sensor and restore accurate temperature reporting to the engine control module. That data helps the ECM manage fuel injection, ignition timing, cold start enrichment, and radiator fan operation. For drivers and technicians servicing Genesis G70, Genesis G80, Hyundai Santa Fe, or Kia Sorento applications, accurate coolant temperature input is critical for stable engine operation and emissions control.

The Sensor Only line from Walker Products focuses on replacement sensors that match factory specifications for electrical response and fit. This part number 211-2146 is built for dependable signal transfer in demanding underhood conditions, including constant coolant contact, heat cycling, and vibration. This part cross-references Monroe Shocks & Struts (e.g., 392202S000) for the same application.

What It Helps Resolve

• Check engine light related to coolant temperature sensor faults
• Incorrect coolant temperature readings at the ECM
• Hard cold starts or extended warm-up behavior
• Rich or lean fuel mixture concerns tied to temperature input
• Cooling fan operation issues caused by inaccurate sensor data
