What is Parking Diesel Heater E01?
1 Answers
Parking diesel heater E01 is a fault code. Causes include system pressure being too low or control circuit damage. System pressure too low: When the pressure value falls below the normal range, a fault code will appear. This can lead to operational failures of the heater, requiring prompt inspection and repair at an automotive repair shop. Control circuit damage: For a vehicle's parking heater, indicator light flashing indicates control circuit issues, which may cause heater malfunctions. The heater utilizes the vehicle's battery and fuel tank for instant power supply and minimal fuel supply, generating heat through gasoline combustion to warm the engine's circulating water for hot starts while also heating the cabin. After using the car heater, the preheated engine experiences significantly reduced wear. Starting a car at extremely low temperatures causes substantial engine damage, so the heater's preheating function effectively minimizes wear.
