TPS RESET

[sipaldi]

Hi All, 2019 phev.

They TPS indicator lit last week so I checked the tyre pressures and the rear offside was down to 15psi. I inflated back to 35psi.
The TPS remained lit on the dash so I entered the settings mode. I held the button down on the reset icon several times but the warning light remains on. Obviously I have driven it several times since etc. Any ideas please?

TPS triggers at less than -20 PSI. So a drop of that magnitude must have happened quite quickly, unless the car has not been driven for a long time. If so, that would suggest you have a fast slow leak that just inflating the tyres won't solve. Have you re-checked the pressure? Obvious, I know, but you don't say you have.

if the pressure is still up then it could be the battery in the valve - either failed coincidently or damaged when driving on the flat tyre - but this, or a problem with the system itself, can only be diagnosed by a dealer. -

I believe some tyre dealers can also read the TPMS, not only Mitsubishi dealers.

Yes, a tyre dealer can check the valve but not the in-car system
