it might be 584k on the meter. its an old fluke I had.i am too blind to see it but im sure its 584k ohms. I went and bought a sensor from the parts store and wouldn't ya know I get ohms thru the sensor. now before I plug it in I need to know if I am supposed to have 4 volts going to the asensor with the car on. don't want to fry this sensor. hey thanks for responding
