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.

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 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.
