Walker Products 211-1074 Engine Coolant Temperature Sensor ECT Sensor

The Walker Products 211-1074 is a direct-fit replacement Engine Coolant Temperature Sensor (ECT sensor / CTS) engineered to OE specifications for reliable performance in the cooling system. This sensor uses electrical resistance to monitor coolant and antifreeze mixture temperature, delivering real-time data to the engine control module (ECM) to support proper engine management.

The ECM depends on accurate coolant temperature readings to control a range of critical functions, including fuel injection, ignition timing, cold start enrichment, cooling fan operation, and exhaust gas recirculation (EGR). A failing or inaccurate sensor can trigger a check engine light and cause symptoms such as poor fuel economy, reduced engine power, rough idle, surging, or stalling.

Key Features:

• Engineered to match OE resistance values, thermal response, and signal output
• Built with durable, heat-resistant materials to withstand coolant exposure, vibration, and extreme temperature cycles
• Direct-fit replacement — no modifications required for installation
• Manufactured and tested to meet or exceed OEM fit, form, and function standards
• Produced by an ISO 9001 / IATF 16949 certified manufacturer

Walker Products has been a trusted supplier of fuel system components and engine management sensors to the automotive aftermarket since 1946. Each sensor undergoes rigorous quality inspections before shipment, ensuring consistent accuracy and long service life.
