Millenia S (2.3L)
WARNING: This page is about a different car, the 1995 Mazda Millenia. However, it is still accessible from the selected car via links, so may be relevant.
Millenia S uses 3 different intake air temperature sensors. Each IAT sensor has unique resistance characteristics. Locate and disconnect sensor(s) in question. See Figure . Using a DVOM, measure resistance across sensor terminals. Replace sensor if resistance is not within specification. See appropriate IAT SENSOR RESISTANCE table.
