What Is the Engine Coolant Temperature Sensor and How Does It Work?
The engine coolant temperature sensor monitors the temperature of your vehicle’s coolant and sends this information to the engine control unit (ECU). This data helps the ECU adjust fuel injection, ignition timing, and other engine functions for optimal performance and efficiency. At Nationwide Mechanics, we connect you with qualified mobile mechanics who can diagnose and replace your coolant temperature sensor conveniently at your location.
Keep in Mind
A faulty coolant temperature sensor can cause inaccurate temperature readings, leading to poor engine performance, increased emissions, and potential overheating. Early diagnosis and replacement prevent costly engine damage.
