GENERALLY OK TO PROCEED WITH CAUTION
Powertrain · Fuel and air · generic OBD-II code
What does P0114 mean?
The intake-air-temperature signal is intermittent.
Can I drive with P0114?
This one is usually fine to drive with in the short term while you get it checked — unless the light starts flashing or the car develops other symptoms. “Generally OK” does not mean nothing is wrong. See Can I Drive It? for a quick read on your exact symptoms.
Common symptoms
- Check engine light
- Usually little or no drivability change
- Occasionally hard cold starts or slightly off running
Possible causes
Possible causes include — not “the part is definitely bad”:
- A loose connector
- An intermittent wire
- A failing sensor
What P0114 does not prove
It does not prove the temperature sensor has failed — the reading can be thrown off by wiring, a connector, or the sensor’s ground.
What you can safely check
- Whether the light is steady or flashing
- That the intake and sensor connector look intact
What a shop may check
An example diagnostic direction, not a guaranteed procedure:
- Scan tool and live intake-air-temperature data
- The sensor wiring and connector
- A comparison against coolant temperature at cold start
What not to do
- Don’t assume the sensor is bad without checking the wiring
- Don’t ignore it if other running problems appear
Generic OBD-II guidance — manufacturer-specific codes and causes vary by make, so always confirm against your vehicle. A code identifies a system or condition; it does not, on its own, prove which part has failed.
