Tyre pressure monitor

[JOSCYN]

Hi All

Just got back from Scotland.

2006 T180 great journey full of action

Main thing is Tire Pressure Warning light is flashing constantly.

Just been to Toyota in Llandudno, they put on Diagnostic £60 and said I needed new Tire Pressure Monitor. £160 fitted.

Any thoughts appreciated please.

I'm not at all sure what you / your dealer mean by needing a "new Tire Pressure Monitor"?

As I understand it, the TMPS system consists of TPMS valves(4 of) that continuously monitor the pressure of the air in the tyre and periodically transmit the measured pressure to a central system that is part of or connected to the ECU. The TPMS valves are powered by in-built batteries that are supposed to last more than 5 years (so most probably less than 10). When the batteries run flat, the TPMS valves need to be replaced ... and they aren't exactly 'cheap'.

Your T180 is 13 years old. If the TPMS valves are original they've done very well. And if the price quoted by your dealer is to replace all four valves that seems very reasonable to me ...

... on the other hand ... ?

Hi Philip

Thank you for your knowledge.

I will question their findings in greater depth and report back.

I have had the car 2 x months so no History of age of sensors.

The report just says requires "Tire pressure Monitor".

A flashing TPMS icon suggests problem with system, whereas a constant lit icon is the sign of pressure issue.
