P0114: Intake air temperature sensor circuit intermittent
The intake air temperature sensor signal drops out or jumps now and then. It is almost always a loose connector or a wire with a poor contact.
| Code | P0114 |
|---|---|
| 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 P0114 means
The temperature of the air entering the engine changes gradually, so if the signal jumps suddenly or vanishes, the ECU knows it is not real and stores this code. Intermittent faults are usually contact problems that show up with vibration, heat or damp.
Most common causes
- Loose connector on the sensor (or on the air flow sensor if built in), or spread pins
- Corrosion or moisture inside the connector
- A wire broken inside its insulation making contact on and off
- A loose earth
- The sensor itself with an intermittent internal fault
Symptoms
- Engine warning light coming and going
- Occasional slight jerking
- Often no noticeable symptoms
Can you drive with P0114?
Yes, no rush The engine is hardly affected. You can keep driving and have it checked when convenient.

How to check it
With the engine idling and intake air temperature on screen, gently wiggle the sensor connector and wiring. If the reading jumps suddenly as you move them, you have found the poor contact.
How to read and clear P0114 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 P0114 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.

How do you clear P0114?
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, P0114 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.
