Walker Products 211-1002 Engine Coolant Temperature Sensor ECT Sensor

The Walker Products 211-1002 is a direct-fit Engine Coolant Temperature (ECT) Sensor engineered to restore proper communication between your vehicle's cooling system and its engine control module (ECM). The sensor monitors coolant temperature through a changing electrical resistance value and relays that data to the ECM in real time, enabling precise control of fuel delivery, ignition timing, cold-start enrichment, and cooling fan operation.

Key Features:

• OEM-Matched Performance: Engineered to match OE specifications for resistance values, thermal response, and signal output for seamless integration with factory engine management systems
• Direct-Fit Replacement: Designed for a direct, no-modification installation with OE-compatible threads, connectors, and mounting positions
• 100% Tested: Every sensor is quality-inspected and tested before shipment to ensure peak performance and reliable operation
• Durable Construction: Built with heat-resistant materials rated to withstand constant coolant exposure, vibration, and extreme temperature cycling
• ISO 9001/IATF 16949 Certified: Manufactured in a certified facility committed to rigorous quality standards

Common Symptoms of a Failing ECT Sensor:

• Hard start or no-start condition
• Engine flooding or rich-running condition
• Illuminated Check Engine Light (CEL)
• Poor fuel economy
