P0113: Intake air temperature sensor circuit high

The ECU sees a voltage that is too high from the intake air temperature sensor, as if the air were freezing. Usually an open circuit.

What P0113 means

The colder the air, the higher the voltage this sensor sends to the ECU. If the voltage rises above what is possible, the ECU reads an absurdly low temperature, often minus 40 degrees. It is almost always an open circuit: an unplugged connector, a broken wire or a sensor broken internally.

Most common causes

  • Sensor connector (or air flow sensor connector if built in) unplugged or loose
  • Broken sensor wire
  • Sensor earth broken or loose
  • Sensor open internally
  • Air filter or filter box refitted badly after a service, leaving the connector off

Symptoms

  • Engine warning light on
  • Engine slightly rich: higher consumption or smoke on diesels
  • Slightly uneven idle when warm
  • Often few symptoms

Can you drive with P0113?

Yes, no rush The engine usually runs almost normally on a backup value. You can keep driving and fix it when convenient, although fuel use may rise a little.

How to check it

If intake air temperature in live data sits at around minus 40 degrees, the ECU cannot see the sensor: first check the connector is plugged in, especially if the air filter was changed recently.

How to read and clear P0113 with Final OBD

Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P0113 with this same explanation and whether it’s confirmed, pending or permanent.

With Free you read this code with its short description for nothing, and clear it if the engine stores it over standard OBD. With Pro you get the full explanation, how the car was running when it was logged (revs, temperature, load) and clearing in every control unit.

Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before the ITV. It’s all in how to read and clear fault codes and in the ITV and OBD.

Similar codes

P0113 is a generic code, so it means the same on any make, for example on Abarth, Citroën, Cupra, Hyundai, Mini, Seat. See what Final OBD does on your car in makes and models.

How do you clear P0113?

With an OBD2 scanner and an app like Final OBD, which clears it for free if it’s stored by the engine control unit. But clearing it only turns the light off: if the cause isn’t fixed, P0113 comes back.
