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.
| Code | P0113 |
|---|---|
| System | Engine and transmission |
| Group | P01xx, Air and fuel metering |
| Type | Generic: it means the same on every make |
| Can you keep driving? | Yes, no rush |
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 its description and whether it’s confirmed, pending or permanent.
If the engine stores it over standard OBD, with FREE you read this code with its explanation for nothing and clear it. With PRO you also read the faults of every control unit and clear them in all of them.
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 an inspection. It’s all in how to read and clear fault codes and in inspections and OBD.

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 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.
Read it on your car
Final OBD reads and clears engine faults through standard OBD for free, each one explained in plain English. With PRO it also reads the faults of every control unit, each make’s own codes included, and clears them in all of them.
