Q: Check Engine Light on Dodge Ram 1500 with code P0073
Engine check light on, Scanner read P0073 code, I replaced ambient temperature sensor, engine check light still stay on with code P0073. Disconnect sensor and check voltage with multimeter on connector, it shows 5 volt, cross one positive and ground or cross both connector still read 5 volt. So I figure there is no broken wire or short. new sensor test with hair dryer and check ohm change down as it get wammer and goes up as it get cooler. Sensor seems working. what can be the problem?
