Walker 211-2019 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor Overview

Walker 211-2019 is an engine coolant temperature sensor for vehicles that rely on accurate coolant data for ECM control. It provides real-time temperature feedback to support fuel injection, ignition timing, cold start enrichment, and cooling fan operation.

This Sensor Only line from Walker Products focuses on direct OE-style replacement parts for factory systems. The 211-2019 is built to match OE resistance values, thermal response, and signal output for consistent readings in Chrysler Pacifica, Jeep Grand Cherokee, Ram 1500, and related applications.

Key Features

• Blade terminal type with a 2-terminal layout
• Female circular connector shape for factory-style connection
• No wiring harness included
• Direct-fit replacement for sensor-only applications
• Heat-resistant construction for coolant and temperature cycling exposure
• Engineered to match OE specifications for resistance, response, and output

How It Works

The coolant temperature sensor sends temperature data from the cooling system to the ECM so the engine can adjust fueling, timing, and fan strategy. Accurate sensor output helps the system react properly during cold starts, normal driving, and high-temperature operation. Walker 211-2019 is built for dependable signal transfer in factory-equipped systems.

This part cross-references Standard Ignition TX261 for the same application.

Common Issues It Can Help Address

• Check engine light related to coolant temperature signal faults
• Incorrect temperature readings on the ECM
• Hard cold starts or extended warm-up behavior
• Cooling fan operation that does not match engine temperature
• Fuel mixture or ignition timing concerns tied to temperature input
