Rockauto has the sensor cheaper, thats about the only way to get rid of the problem is to replace the sensor

 

Agree take the pwr wire off. Code gone you know pwr wire is bad. If code is still there replace the sensor.

 

Lupe,

Below is the description of code P0113.

P0113-INTAKE AIR TEMPERATURE SENSOR CIRCUIT HIGH

1. When Monitored: With the ignition on. Battery voltage greater than 10.4 volts.
2. Set Condition: The PCM detects that the Intake Air Temperature Sensor input voltage is above the maximum acceptable value

Possible Causes

(K21) IAT SIGNAL CIRCUIT SHORTED TO VOLTAGE
(K21) IAT SIGNAL CIRCUIT OPEN
(K900) SENSOR GROUND CIRCUIT OPEN
IAT SENSOR
POWERTRAIN CONTROL MODULE (PCM)

 

Like we said just replace the 30 dollar sensor, its more than likey your problem
