Tyre pressure indicator

[MarkRubinstein]

For some time we have had the tyre pressure indicator light come on and a message to say check the rear right tyre when we started the engine. The tyre pressure was fine and if I reset the tyre pressures it would be fine for a day or two then the light and message would come back.

For the past few days the message has changed to say that the loss indicator is currently not available and the yellow warning light still comes on.

Any advice ?

It depends which system you have.
The basic, doesn't show individual pressures, depends on the ABS sensor on each wheel measuring the rotational speed of the wheel as a flat tyre has a different circumference thus does more revolutions/mile. So it could be an ABS sensor problem.
If you have the active system that shows individual tyre pressures, each wheel has an individual sensor that has a battery. Either the sensor has failed or it needs a new battery.
