Walker 211-2017 Engine Coolant Temperature Sensor - Radiator
Engine Coolant Temperature Sensor Overview
Walker 211-2017 is an engine coolant temperature sensor for vehicles that rely on accurate coolant data for ECM control. It reads coolant temperature in real time so the engine computer can manage fuel injection, ignition timing, cold start enrichment, and cooling fan operation. This Sensor Only line is built for direct replacement service on select Toyota and Lexus applications.
Compatible With select 2018-2025 Toyota and Lexus models, including Toyota Camry, Corolla, Highlander, RAV4, Sienna, Tundra, Venza, and Lexus NX, RX, ES, UX, and LX applications. Walker 211-2017 is also listed for specific radiator-mounted and radiator-pipe locations on certain Toyota Prius, Prius Prime, and RAV4 models.
Key Features
- Engine coolant temperature sensor for ECM temperature input
- OE-style resistance values, thermal response, and signal output
- Direct-fit design for factory-style replacement
- Durable, heat-resistant construction for coolant and vibration exposure
- 2-terminal pin design with female oblong connector
- No wiring harness included
Product Details
Walker Products 211-2017 is engineered to deliver accurate coolant temperature readings so the ECM can adjust engine operation based on current conditions. The sensor uses a 2-pin, female connector with an oblong shape and pin terminals, matching the electrical interface used on the listed Toyota and Lexus platforms. As part of the Walker Sensor Only line, this component focuses on the sensor itself for straightforward replacement service.
This part cross-references Standard Ignition TX319 for the same application. Walker 211-2017 also interchanges with 8942233040 and WT5077.
Common Problems It Can Address
- Check engine light related to coolant temperature signal faults
- Incorrect fuel mixture during cold start or warm-up
- Unstable idle caused by inaccurate temperature input
- Cooling fan operation issues tied to sensor readings
- Poor fuel economy or elevated emissions from incorrect ECM temperature data
Installation Notes
Verify the connector shape, terminal count, and mounting location before installation. This listing includes N/A and radiator-position applications, so confirm the exact vehicle and sensor location against the fitment data for your Toyota Camry, Corolla, RAV4, Highlander, or Lexus NX/RX application. No wiring harness is included, so reuse the existing harness connection where applicable.
For best results, inspect the cooling system connector and surrounding components for corrosion, coolant contamination, or damaged terminals before installing the new sensor. Clear diagnostic trouble codes after replacement and confirm the ECM receives a stable temperature signal.
Quality Assurance
Walker Products designs these coolant temperature sensors to match OE specifications for resistance, thermal response, and output signal, supporting reliable integration with factory engine management systems. The heat-resistant construction is built for continuous exposure to coolant, vibration, and temperature swings encountered in daily service.
