P0113: Intake Air Temperature Sensor Circuit High Input
Can you still drive? Yes, this is a low-severity code. The ECM will use a default temperature value, but fuel efficiency may be slightly affected.
What Does P0113 Mean?
Code P0113 indicates that the intake air temperature sensor is reading an abnormally high voltage, which corresponds to an extremely low temperature reading. The IAT sensor is often integrated into the MAF sensor and provides air temperature data for fuel delivery calculations. A high circuit input typically indicates an open circuit or disconnected sensor.
Need to read your codes?
An OBD-II scanner lets you read and clear diagnostic trouble codes from your vehicle's computer. Most scanners work with any car made after 1996.
