Walker Products 211-1073 Engine Coolant Temperature Sensor ECT Sensor

The Walker Products 211-1073 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. The ECT sensor measures coolant temperature through a changing electrical resistance value and transmits that data to the engine control unit (ECU), enabling the ECM to optimize fuel injection, ignition timing, cold start enrichment, and cooling fan operation.

A failed or degraded coolant temperature sensor can trigger symptoms such as hard starting, engine flooding, poor fuel economy, erratic idle, or an illuminated check engine light. Replacing it with a precision-engineered Walker Products unit restores accurate thermal feedback and helps protect your engine from the consequences of incorrect fuel and timing calculations.

Key Features:

• Measures coolant temperature via changing electrical resistance and relays data to the ECU
• Engineered to match OE specifications for resistance values, thermal response, and signal output
• Direct-fit design installs into the factory sensor port with no modifications required
• 100% tested for peak performance prior to packaging and shipment
• Built with durable, heat-resistant materials rated for high-temperature, high-vibration under-hood environments
• Manufactured in an ISO 9001 / IATF 16949 certified facility
• Meets or exceeds all Original Equipment Manufacturer (OEM) specifications and test requirements
