Intake Air Temperature Sensor 1 Circuit High Input
The computer thinks the incoming air is extremely cold because the intake air temperature sensor signal is too high. This is usually caused by a bad sensor, damaged wiring, a poor connector, or sometimes a problem with the mass air flow sensor.
You can usually drive short distances, but the engine may run poorly, use more fuel, or be harder to start. Repair it soon to avoid drivability problems and increased emissions.
P0113 sets when the powertrain control module detects an intake air temperature sensor voltage that is above the normal range for too long. On most systems, a high input means high voltage from the sensor circuit, which usually indicates an open circuit, failed sensor, or disconnected wiring. Some vehicles have the IAT sensor built into the mass air flow sensor assembly.
It means the engine computer is seeing an intake air temperature sensor signal voltage that is too high. This usually points to an open circuit, bad sensor, or connector problem.
A dirty air filter is not the most common cause, but it can contribute to airflow and sensor issues on some vehicles. Wiring and sensor faults are much more common.
Not always. Some vehicles have a separate IAT sensor, while others build it into the MAF sensor. If the IAT is integrated, a bad MAF assembly can set P0113.
Yes. Incorrect intake air temperature data can cause the computer to miscalculate fuel delivery, which may increase fuel consumption.
On many vehicles, yes. It is often a simple part to access and replace, but you should inspect the wiring and connector before installing a new sensor.
