  • Apparatus and methods related to coolant diverter valves
    Patent number: 12359608
    Abstract: A method and apparatus for fault detection of a coolant diverter valve. The coolant diverter valve is arranged in a coolant system to control flow of coolant from a coolant reservoir to a diesel exhaust fluid tank. At least a first sensor is provided for measuring the pressure and/or temperature of the coolant. During operation of the coolant diverter valve, as required from time to time, the coolant diverter valve is commanded to open by energising the coolant diverter valve and commanded to close by de-energising the coolant diverter valve. Based on readings from the first sensor a controller can determine if the coolant diverter valve has failed to close when the coolant diverter valve is de-energised.
