Abstract
A method of averaging coolant temperature for an internal combustion engine in an automotive vehicle includes the steps of sensing coolant temperature of the engine based on an output signal of a coolant temperature sensor, determining an initial value of coolant temperature based on the output signal from the coolant temperature sensor, storing the determined initial value as an initial coolant temperature value (CLTMP1) and as an averaged coolant temperature value (AVCT), periodically updating the AVCT value, and using the AVCT value to control the output of fuel injectors of the engine.
