Walker 211-2055 Engine Coolant Temperature Sensor - Radiator
Walker 211-2055 Engine Coolant Temperature Sensor
Walker 211-2055 is a sensor-only engine coolant temperature sensor that sends real-time coolant temperature data to the engine control module. It supports fuel delivery, ignition timing, cold-start enrichment, and cooling fan operation for accurate engine management.
Sensor Only Design
The Walker Sensor Only line focuses on direct replacement sensors built to OE-style electrical and thermal specifications. This part uses a blade terminal type, a rectangular female connector, and a 2-terminal layout, with no wiring harness included. The result is a straightforward replacement for technicians servicing a failed coolant temperature sensor or diagnosing a check engine light.
- Blade terminal type
- Rectangle connector shape
- 2-terminal female connector
- No wiring harness included
- Direct-fit replacement sensor
Detailed Product Overview
Walker Products engineers this coolant temperature sensor to match factory resistance values, thermal response, and signal output so the ECM receives accurate temperature feedback from the cooling system. That accuracy helps the engine manage fuel economy, emissions, and drivability across changing operating conditions. Part number 211-2055 is a practical OE-style replacement for radiator-mounted applications on select Toyota Yaris, Toyota Yaris iA, Scion iA, and Mazda 2 models. This part cross-references Standard Ignition TX279 and NTK EF0180 for the same application.
What This Sensor Helps Address
- Incorrect coolant temperature readings
- Check engine light related to coolant temperature input
- Hard cold starts or poor cold-start enrichment
- Cooling fan control concerns
- Fuel mixture and ignition timing issues caused by faulty temperature data
Installation Notes and Fitment
Fits 2019 Toyota Yaris, radiator. Fits 2017-2018 Toyota Yaris iA, radiator. Fits 2016 Scion iA, radiator. Fits 2011-2014 Mazda 2, radiator. Verify the connector style, terminal count, and radiator location before installation. Part number 211-2055 is a direct-fit sensor-only replacement, so no harness is included.
Quality Assurance
Walker Products builds this sensor to OE specifications for resistance, thermal response, and signal output to support reliable integration with factory engine management systems.
