Walker Products 211-1075 Engine Coolant Temperature Sensor ECT Sensor

The Walker Products 211-1075 is a direct-fit replacement engine coolant temperature (ECT) sensor engineered to restore accurate thermal monitoring to your vehicle's engine management system. This sensor measures coolant temperature through changing electrical resistance and transmits real-time data to the engine control module (ECM), which relies on this input to optimize fuel delivery, ignition timing, cold-start enrichment, and cooling fan operation.

Walker Products has been manufacturing fuel system and engine management components since 1946, and as an ISO 9001/IATF 16949 certified manufacturer, each sensor undergoes rigorous quality inspections before leaving the facility. The 211-1075 is built to match OEM resistance values, thermal response curves, and signal output — ensuring seamless integration with factory engine control systems without the need for recalibration or modifications.

Key Features:

• Measures coolant temperature via changing resistance for accurate ECM input
• Engineered to meet or exceed OEM specifications for signal response and thermal accuracy
• Built with heat-resistant, durable materials rated for constant exposure to coolant and high-vibration environments
• Direct-fit replacement — installs without modifications
• Helps resolve symptoms such as hard starts, engine flooding, poor fuel economy, rough idle, and check engine light
• Manufactured by an ISO 9001/IATF 16949 certified facility

Recommended service interval for coolant temperature sensors is every 25,000 to 35,000 miles, or when symptoms of sensor failure are present. The Walker Products 211-1075 ECT sensor delivers the OE-grade accuracy and reliability that professional technicians and DIY mechanics depend on.
