According to Haynes, at 38 F, the resistance should be 35 to 40 K-ohms, at 182 F (1.9 to 2.5 K-ohms) and 218 F (1.0 to 1.3 K-ohms).
And since the PCM uses both the MAF and IAT to determine the amount of fuel to achieve the ideal air/fuel mixture ratio, you might as well clean the MAF sensor while you are at it.
