Tyre Pressure Warning System

The life of TPMS sensor batteries is anticipated to be anywhere between five and ten years. If a sensor battery dies, the TPMS warning light will stay on as the system is no longer monitoring pressures. As the car is around 8 years old, may be worth getting the sensors checked.

Bear in mind it is an MOT fail if the TPMS warning light is illuminated.

 

Delbois hasnt updated his profile, further up he mentions that this is on a 2020 car

Cheers Frosty... I thought I'd added the new car but must have forgotten to save... thanks for the heads up... sorted 👍

Went for a 20 mile drive today but TPWS light still solid. I've also noticed the warning light flashes for a minute when the car is started. The manual states this is indicative of a faulty TPWS system so I'll get it checked during the next service.

Discussed with Toyota dealer service manager today who said the TPWS issue was not one they'd come across with the Corolla before.  He confirmed it could wait until the service in June to be checked out.

My pet hate response, along with, "We dont stock that,  never been asked for it" 👿

Perhaps better than, "I'm sorry Sir, there is such a demand for that it is out of stock."  Sub text, even when we get you one you will soon be back for another 🙂

Once had a speedometer cable break, the new part was waiting for me on the counter and the storeman told me how to change it and how to make the tool necessary for access.  The final bit was don't put that nut back on.  Fortunately it didn't break again.

Or as I was told by my Honda dealer when I reported my door mirrors randomly folding in and out while driving 'We can't do anything until they actually fail or start doing it continuously'.

Hi, I am in the same situation. TPWS light blinks for around a minute and then goes solid. Can't reset it.

I was just wondering what the problem and the fix was?

Hi - it turned out to be a faulty valve unit on the rear OS wheel. A new one was fitted by the dealer under warranty and it's been fine ever since. Apparently the diagnostics software only identifies the ID no. of each unit and its pressure reading but NOT its actual location on the car. Identifying which unit is faulty involves letting pressure out of each tyre in turn until the one showing the fault code registers a drop.

I think that's by design so that you can swap the wheels front to back and keep the wear balanced without the system having a hissy fit. Not very common practice here in the UK but it is in other markets.
