P0113 Code
Intake Air Temperature Sensor Circuit High

The IAT sensor is reading impossibly hot/cold — usually a wiring issue or the sensor itself, which often lives inside the MAF assembly.
Can you keep driving?
Yes — minor drivability and fuel economy effects.

⚠️ Don't get ripped off
This is one of the cheapest sensors on the car. If it's built into your MAF assembly, the fix costs more — but a steep quote for a standalone IAT sensor deserves a second opinion.
