Mitsubishi uses direct TPMS on Outlander, ASX, Shogun and L200 — inflate to the placard and the light clears on a short drive; most models relearn automatically.
Why the Mitsubishi tyre pressure light is on
Each wheel has a sensor reporting live pressure. The light means a genuinely low tyre, a cold-weather drop, or a sensor at the end of its battery life — usually 6–8 years. On Outlander PHEV the light also appears if a wheel has been changed and the sensor not programmed in.
Mitsubishi tyre pressure light reset — step by step
- Set all four tyres cold to the driver's door pillar placard pressures.
- Switch the ignition ON.
- On Outlander, Outlander PHEV, Eclipse Cross and ASX: most versions relearn automatically — there is no menu reset, so simply correct the pressures.
- On models fitted with a TPMS reset switch (some L200 and Shogun): press and hold it with the ignition ON until the light blinks.
- Drive above 20mph for 10–20 minutes so every sensor transmits and the light goes out.

If the light won't go off
If the light flashes for about a minute at start-up then stays on, a sensor isn't reporting — that's a replacement job, not more air. If pressures are correct and it's steady, get the stored fault read; older Outlanders occasionally hold a historic low-pressure warning that needs clearing with a tool.
What it costs
Reset is free. Sensor replacement £40–£75 per wheel fitted at an independent including programming; dealer pricing is typically £95–£150 per wheel.
Bob's workshop tip
L200 owners who carry heavy loads should use the laden pressure column on the placard, not the unladen one. Running unladen pressures with a tonne in the back overheats the rears and will keep tripping the warning.

What Bob keeps in the boot
A pump puts air back in, but it will not seal the hole. For a nail or a screw in the tread, the repair itself is the Emergency Puncture Repair Kit — £9.99 with free UK delivery: rubber rope plugs, reamer, T-handle tool and rubber solution, posted from the workshop in Birnam, Dunkeld. If you would rather not take a wheel off at the roadside, the quick-fix tyre repair spray is the no-tools option. Keeping the pressures right in the first place is covered in tyre pressures by registration and resetting the tyre pressure warning light, and the pump itself in Bob's electric tyre pump picks.
Be straight about what a plug is: a get-you-home repair for small punctures in the central three-quarters of the tread. Never plug sidewall or shoulder damage, drive gently afterwards, and have the tyre inspected or replaced by a tyre specialist as soon as you can.
