Tire Pressure Low (TPMS Soft Warning) -- Inflate Tire Soon
The TESLA-UI_A014 (Tesla TPMS / User Interface) EV fault code means: Tire Pressure Low (TPMS Soft Warning) -- Inflate Tire Soon. This is a low severity code.
- Keep driving?
- Yes, but fix soon
- DIY difficulty
- beginner
- Estimated cost
- $0 to top off at a pump; $20-$45 if a slow-leak repair turns out to be needed.
A $30 car code reader can't do diesel. The HD7000 reads full-system codes and does parked DPF regen, idle/speed-limit, and service resets from the cab — on everything from a 6.7 Cummins/Power Stroke/Duramax pickup to Class-8 trucks (Detroit, Paccar, CAT, Volvo, Mack, International).

Common Symptoms
- Low-tire-pressure notification on the touchscreen
- A tire reads modestly below target on the pressure screen
- Commonly appears overnight as temperatures fall
- No immediate drivability change
Probable Causes (Ranked by Likelihood)
- Mild under-inflation, usually a normal cold-weather pressure drop Very Likely
- Slow seepage past the valve stem or a small leak in its early stage Possible
- Pressure not topped up since the last seasonal change Possible
Step-by-Step Diagnostic Procedure
Check all four pressures cold against the door-jamb placard and inflate the low tire(s) to spec.
This is the early "soft" warning -- it precedes the more urgent UI_a013 hard warning, so address it before pressure falls further.
If the same tire keeps reading low after inflating, inspect it for a slow leak (nail, valve stem) and repair.
Frequently Asked Questions
What is the difference between UI_a014 and UI_a013?
UI_a014 is the early "soft" low-pressure warning -- a tire is modestly low. UI_a013 is the "hard" warning for a significantly low tire and is more urgent. Inflating at the soft-warning stage usually prevents the hard warning.
Is it safe to drive with UI_a014?
Yes, for normal driving in the near term, but inflate the tire to the placard pressure soon. Driving on a low tire for long reduces range and efficiency and accelerates tire wear.
