Walker Products 211-1069 Engine Coolant Temperature Sensor ECT Sensor

The Walker Products 211-1069 Engine Coolant Temperature Sensor (ECT Sensor) is a direct-fit OE replacement designed to restore accurate coolant temperature monitoring to your vehicle's engine management system. This sensor works by measuring coolant temperature through changing electrical resistance and transmitting that data in real time to the engine control module (ECM), enabling precise adjustments to fuel injection, ignition timing, cold start enrichment, and cooling fan operation.

An accurate ECT sensor signal allows the ECM to optimize engine performance, fuel economy, and emissions. Common symptoms of a failed coolant temperature sensor include hard starts, engine flooding, poor fuel economy, and an illuminated check engine light. Replacing a faulty sensor restores proper engine management and protects against related drivability issues.

Key Features:

• Measures coolant temperature via changing resistance and sends real-time data to the ECM
• Engineered to match OE specifications for resistance values, thermal response, and signal output
• 100% tested for peak performance prior to packaging and shipment
• Built with durable, heat-resistant materials to withstand exposure to coolant, vibration, and extreme temperature swings
• Direct-fit design — no modifications required for installation
• Manufactured to meet or exceed OEM standards and specifications
• Produced in an ISO 9001/IATF 16949 certified facility
