Walker Products 2112072 Engine Coolant Temperature Sensor ECT Sensor

The Walker Products 211-2072 is a direct-fit replacement Engine Coolant Temperature Sensor (ECT sensor) engineered to meet or exceed original equipment specifications. Designed for seamless integration with the engine control module (ECM), this sensor delivers accurate, real-time coolant temperature data that the ECM relies on for optimal engine management.

How It Works:

The engine coolant temperature sensor continuously monitors coolant temperature and transmits that data to the ECM. This information is critical for regulating fuel injection, ignition timing, cold-start enrichment, and cooling fan operation — helping protect the engine from overheating and ensuring efficient combustion across all operating conditions.

Key Features:

• 100% engineered and tested to OE specifications in fit, form, and function
• Matched OE resistance values, thermal response, and signal output for reliable ECM integration
• Built with durable, heat-resistant materials to withstand constant exposure to coolant, vibration, and extreme temperature swings
• Direct-fit design — no modifications required for installation
• Supports accurate fuel management, improved fuel economy, and emissions control
• Manufactured by Walker Products, an ISO 9001 / IATF 16949 certified company

Walker Products has been a trusted supplier to the automotive aftermarket since 1946, producing engine management sensors and fuel system components that meet rigorous quality standards. The 211-2072 ECT sensor is a reliable, cost-effective solution for restoring proper engine temperature monitoring and resolving check engine light codes related to coolant temperature.
