Walker Products 211-1039 Engine Coolant Temperature Sensor ECT Sensor

The Walker Products 211-1039 Engine Coolant Temperature Sensor (ECT Sensor) is a direct-fit OE replacement sensor engineered to restore proper engine management function. The engine coolant temperature sensor monitors coolant temperature through changing resistance and transmits real-time data to the engine control module (ECM), which uses that signal to regulate fuel injection, ignition timing, cold start enrichment, and cooling fan operation. An accurate ECT reading allows the ECM to optimize engine performance, fuel economy, and emissions output.

Key Features:

• 100% engineered and tested to OE specifications for resistance values, thermal response, and signal output
• Direct-fit design ensures easy installation with no modifications required
• Built with durable, heat-resistant materials to withstand constant exposure to coolant, vibration, and extreme temperature swings
• Engineered to match OE fit, form, and function for seamless integration with factory systems
• Manufactured by Walker Products, an ISO 9001/IATF 16949 certified company with over 75 years of experience

Symptoms of a Failing Coolant Temperature Sensor:

• Hard start or no-start condition
• Engine flooding or rich running
• Poor fuel economy
• Rough idle, surging, or stalling
• Illuminated Check Engine Light
