DTC P1193 : Inlet Air Temperature Sensor Voltage High

DTC P0172 : 1 / 1 Fuel System Rich

Both of these codes are pointing towards a faulty inlet air temperature sensor, or bad wiring to the sensor. Suggest replacing sensor if wiring is OK. Inlet air temp. Sensor (AKA the IAT or Intake Air Temp. Sensor) is located near the throttle body.
