Code P3075 Description

The cooling system's function is to maintain an efficient engine operating temperature during all engine speeds and operating conditions. The cooling system is designed to remove various amounts of the heat produced by the burning of the air-fuel mixture. When the engine is cold, the coolant does not flow to the radiator until the thermostat opens. This allows the engine to warm up quickly. The Diagnostic Trouble Code (DTC) will be set when the Engine Coolant Pump Current is not within a calibrated range for greater than 3 s.
