Abstract
A method for operating a device at a desired temperature is described. In one example, current supplied to a heater that melts a wax medium or material controlling flow through a valve is adjusted to reduce valve opening and closing delay. The method may improve device temperature control, thereby reducing device emissions, enhancing device performance, and improving device durability.
