Walker 211-2027 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor Overview

Walker 211-2027 is a sensor-only engine coolant temperature sensor built to report cooling system temperature data to the ECM in real time. It supports fuel injection, ignition timing, cold start enrichment, and fan operation for accurate engine control.

This Walker Sensor Only line is focused on direct replacement fitment and OE-style signal accuracy for factory-managed cooling system operation. It is a practical choice for Ford Bronco, Ford F-150, and Lincoln Aviator applications that require a reliable coolant temperature reading.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• Direct-fit design for factory-style installation
• Matches OE resistance values, thermal response, and signal output
• Heat-resistant construction for coolant and high-temperature environments
• 2-pin, female circular connector
• Wiring harness not included
• Part number: 211-2027

Detailed Product Information

Walker Products 211-2027 is engineered to deliver consistent coolant temperature feedback so the ECM can adjust engine operation based on actual cooling system conditions. Accurate sensor output helps maintain proper fuel delivery, ignition timing, and radiator fan control across a wide range of operating temperatures. The sensor is built for durability in constant coolant exposure, vibration, and repeated heat cycling.

Walker’s Sensor Only product line focuses on replacement sensors that integrate with factory systems without modification. This makes 211-2027 a straightforward option for technicians and DIY repairs on Ford and Lincoln vehicles where a coolant temperature sensor fault can trigger drivability concerns or a check engine light.

This part cross-references Standard Ignition TX316 for the same application.

Common Issues This Sensor Can Address

• Check engine light related to coolant temperature sensor performance
• Incorrect engine temperature readings sent to the ECM
• Hard cold starts or poor cold-start fuel enrichment
• Cooling fan operation that does not match engine temperature
• Fuel economy or drivability issues tied to inaccurate temperature input

Installation Notes

Verify connector style, terminal count, and sensor location before installation. This sensor uses a 2-terminal female circular connector and does not include a wiring harness. Confirm the vehicle uses the correct sensor-only configuration, especially on Ford Ranger and Lincoln Aviator applications where notes specify thread-in or engine block placement.
