Fig. 3: Testing A/C Engine Coolant Temperature Switch Courtesy of Mitsubishi Motor Sales of America. AIR THERMOSENSOR & AIR INLET SENSOR 1) Disconnect sensor connector at evaporator case. See Fig. 12. Using ohmmeter, measure resistance between sensor terminals. See AIR THERMOSENSOR & AIR INLET SENSOR SPECIFICATIONS table. 2) If resistance is not within specifications, faulty sensor must be replaced. If resistance is within specifications and all other components are okay, replace A/C Compressor Control Unit (ACCU).
