Is it safe to drive with this code?

Many vehicles can be driven cautiously for short distances with P0114, though you may notice poor performance or hesitation. The ECU often substitutes a default air temperature value. Prolonged driving in failsafe mode can lead to carbon build-up or ignition issues, so prompt diagnosis is advisable—see our site disclaimer for further guidance.

P0114 itself does not automatically cause MOT failure; what matters is whether the malfunction indicator lamp (check engine light) is illuminated at the time of test. If the light is on, the tester may record this—refer to our MOT disclaimer for full details on emissions and warning-light provisions.

Roughly how much does it cost to fix?

Costs vary widely depending on the root cause. Simple wiring repairs or connector cleaning may fall in the low two-figure range (labour only). Replacing the IAT sensor typically runs low three-figure (parts and labour combined). If ECU reprogramming or replacement is needed—rare but possible—expect mid to high three-figure or even four-figure sums at a main dealer. Independent garages often charge less for labour, and sensor-only jobs are usually quicker than module work.

Can I just clear the code and carry on?

Clearing the code without addressing the underlying intermittent fault will typically see it return within a few drive cycles. Because the issue is intermittent, it may seem resolved temporarily, but proper diagnosis is needed to prevent recurrence and potential knock-on effects on fuel efficiency or emissions.

ⓘ Information only. This page provides general educational information about fault code P0114. We do not assess the urgency or safety implications of any specific fault. That requires in-person diagnosis by a qualified mechanic. Full terms.

Recommended next steps

Whether a fault is urgent, drivable, or routine depends entirely on the cause on a specific vehicle, and that can only be determined by a qualified mechanic with diagnostic equipment. If a warning light is illuminated, the most reliable next step is professional diagnosis.

What does P0114 mean?

P0114 is a Powertrain (engine, transmission, fuel system) fault code. It indicates: Intake Air Temperature Sensor 1 Circuit Intermittent.

This is a standardised OBD-II code. The technical definition is the same regardless of the make or model of vehicle, although specific causes and symptoms can vary between vehicles.
