Failure in Chevrolet Rodeo 1998 V6

I have a Rodeo V6, 3.5 Lts of 1998, the problem is that the check is on, and I already scan it and I get P0113 High Voltage in IAT circuit, the live data had the T of the admission air of -40 Celsius, but I look for the IAT and only have MAF of 3 cables and in the manual it says that it must be of 5. There is some way to turn off that chek .... Ah in the mornings it does not turn on easily, and during the day he turns on the 2nd time he tries. It is lacking power too.

Hello, good night you will have the vin number of your unit to see if I can help you greetings, Atte. Luis Santiago.

I really don't have that data ... for now ...
