Causes and Fixes P0097 Code: Intake Air Temperature (IAT) Sensor 2 Circuit Low

How to fix P0097 Code: Intake Air Temperature (IAT) Sensor 2 Circuit Low
A P0097 code is set when the computer (ECM/PCM) detects an irregularity in the intake air temperature #2 readings. IAT Sensor #2 is reporting high temperatures when the engine temperature is low.
The Intake Air Temperature sensor (IAT) monitors the temperature of the air entering the engine.
The engine computer uses the information to calculate air density so it can adjust the air/fuel ratio.
Cold air is more dense than hot air, so cold air requires more fuel to keep the correct air/fuel ratio.
This helps the engine to get more power and better gas mileage.
The IAT sensor is a Thermistor, which is a resistor whose resistance changes with temperature.
An IAT sensor can be built-in with the MAF sensor, MAP sensor, or by itself with single or multiple sensors.
Possible Causes of a P0097 Code:
Bad IAT Sensor #2
IAT Sensor Wiring
