P0113 Intake air temperature sensor 1 circuit high (bank 1)
What P0113 means
The voltage from the intake air temperature sensor is above range, which the engine computer reads as extremely cold air (often around -40 °C in live data). This usually means the circuit is open. The computer uses a default value instead.
P0113 is a generic SAE J2012 code: it means the same on every make. The exact cause still depends on the car, so read the freeze-frame data before replacing parts.

Parts and labour at an independent workshop in Europe. Main dealers charge more; the cause decides the bill, not the code.
Symptoms
- Check engine light on
- Usually no change in driving
- Possible slightly higher fuel consumption
Common causes
- Sensor connector left unplugged, for example after air filter work
- Open circuit in the signal or ground wire
- Failed IAT sensor
- Corroded or loose connector pins
Can I keep driving with P0113?
You can keep driving and check it when convenient. The engine runs normally on a default value, with at most a small increase in fuel consumption.
What to check first
- Check that the IAT (or MAF) connector is plugged in, especially if the air filter was recently changed.
- Read the live IAT value; around -40 °C means an open circuit.
- Bridge the signal and ground pins at the connector with the key on: if the reading jumps to a very high value, the wiring is good and the sensor has failed.
- Repair the wiring or replace the sensor.
