Code P2558 Description

The P2558 diagnostic trouble code (DTC) refers to the Engine Coolant Level Sensor/Switch Circuit Low. This code is set when the engine control module (ECM) detects a low voltage signal from the engine coolant level sensor or switch. The engine coolant level sensor is responsible for monitoring the coolant level in the radiator or coolant reservoir. When the coolant level drops below a certain point, the sensor sends a signal to the ECM to alert the driver of a potential issue.
