Walker 211-2144 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Honda Clarity

Walker 211-2144 is an engine coolant temperature sensor built to send real-time coolant temperature data to the ECM. For 2017-2021 Honda Clarity models, this sensor supports accurate fuel delivery, ignition timing, cold-start enrichment, and cooling fan control.

Walker Products Sensor Only line focuses on direct replacement sensors that match OE-style electrical response and signal output for factory system integration. The 211-2144 is a fit for the engine coolant pipe location on Honda Clarity applications.

Key Features

• Engine coolant temperature sensor for ECM temperature input
• Fits 2017-2021 Honda Clarity, engine coolant pipe location
• Pin terminal design with 2 terminals
• Female circular connector shape
• Direct-fit replacement with no wiring harness included
• Built with heat-resistant materials for coolant-system exposure
• Walker 211-2144 engineered to OE resistance and signal characteristics

Detailed Description

The Walker Sensor Only 211-2144 monitors coolant temperature and relays that information to the engine control module so the vehicle can adjust operating strategy in real time. On Honda Clarity models, accurate coolant temperature data helps the ECM manage cold starts, fuel injection, ignition timing, and radiator fan operation. This part cross-references Standard Ignition TX317 for the same application.

Walker Products designs this sensor to match OE specifications for resistance values, thermal response, and output signal, helping maintain consistent communication with factory electronics. If you are replacing a failed sensor or diagnosing a check engine light on a 2017-2021 Honda Clarity, Walker 211-2144 provides a direct replacement for the engine coolant pipe sensor location.

What It Helps Solve

• Incorrect coolant temperature readings reported to the ECM
• Check engine light related to coolant temperature sensor faults
• Hard starting or rough cold-start operation
• Improper fuel mixture caused by inaccurate temperature input
• Cooling fan control issues tied to sensor signal errors

Installation Notes

Verify the connector style, terminal count, and sensor location before installation. This part uses a 2-terminal female circular connector and does not include a wiring harness. Confirm the engine coolant pipe mounting point on the vehicle before replacing the original sensor. Walker 211-2144 is a direct-fit sensor for the listed Honda Clarity applications.

Quality Assurance

Walker Products builds this sensor to OE-style electrical and thermal specifications for reliable integration with factory engine management systems. The durable, heat-resistant construction is designed for continuous exposure to coolant, vibration, and temperature cycling.
