i want to check this
PUT THE AMP METER IN SERIES INTO ONE OF THE WIRES GOING TO THEPRESSURE ACTUATOR, UNPLUG THE COOLANT TEMPERATURE SENSOR ANDCONNECT THE SENSOR SIMULATOR ACROSS THE MULTI PLUG AND CHANGE THERESISTANCE. THE PRESSURE SHOULD THEN CHANGE AS THE RESISTANCE ISCHANGED. THIS DETERMINES THAT THE ELECTRONIC CONTROL UNIT AND THEPRESSURE ACTUATOR ARE WORKING CORRECTLY

and connect the sensor simulator across the multi plug.... i don t understand this sorry for my english
thanks
