@alpha.rydes.tech: The engine temperature sensor provides the ECU with information about coolant or engine temperature, depending on the sensor design. The computer uses this data to influence fueling, ignition, cooling-fan operation, and other functions. A faulty sensor can cause difficult starting, poor fuel economy, abnormal temperature readings, or drivability problems. #alpharydestech #Sensors #mechanic #creatorsearchinsights #mechanicalautomotive
