I have a MAP sensor question. Does anyone know where I can cross reference the numbers that are hot stamped on the MAP Sensor with the part numbers? I have a GM MAP sensor that doesn't have the white sticker with the part number on it. However there are several number on the casing itself. The hot stamped numbers are on the back where the pigtail plugs in and the numbers are 103 3160. Other number on the plastic housing include 466, and 45 17406. Thanks for the help.
