Tyre Pressure Monitor System

Recommended Posts

The Tyre Pressure warning light is illuminated on my 2017 Avensis Tourer, although the tyre pressures are correct and I'm unable to reset it using the procedure as detailed in the manual. 

Anybody got any ideas of the cause of the problem and is the TPMS covered by the 5 year warranty. 

Thanks for any help.

When checking are you sure you’re getting an accurate reading??

Yes the tyre pressures are 36 PSI on the front and 33 PSI on the rear. I've gone through the reset tyre pressure procedure to no avail. I'm wondering if one of the sensors has failed or the Battery has lost its charge.

Could be sensors, the Battery is easily checked.

How do you do that, please.

Does yours have a display to tell you what PSI each wheel is at?

Or is it just the indicator light?

If the latter, will be easier to get a garage to look at it as they will have the scanner tool to check the TPMS sensors are signalling properly.

The TPMS system is covered by the warranty, but I'm not sure if the individual sensors are... Hopefully they are, as they are quite pricey!

No it doesn't have individual display, just the indicator light. 

It's getting serviced and MOT next week at a Toyota garage, so hopefully it's covered by the warranty. 

Thank you.

Found this:

"Most TPMS sensors run on batteries that are built into the sensor and these batteries are not replaceable. The life expectancy of the lithium ion batteries in a TPMS sensor is anywhere from 5-10 years." 

Whether this applies to Toyota and warranties I don't know.

I suppose it comes down to, if Toyota consider it as a consumable item, as its not specifically mentioned as not being covered by the warranty.

suppose if under warranty the car id let toyota fix it for free i was trying to find another video where was on youtube of someone cutting out old Battery putting in a new one and those a4 sheets of paper clips . clip one of those on to it and the pressure squeezing down is the pressure needed didnt even have to go to the bother putting into one of those pipes setup mind you thats a good idea to im going to do that if mine gives me any bother

Yeah you can replace the lithium cells but it's a PITA because of the potting compound they use to weather-proof the TPMS. I really don't know why nobody makes them more easily replaceable - It's so pointlessly wasteful to throw the whole thing away than just swap the cell out!

In fact why do they even need cells? I'm sure it wouldn't be too hard to power them from the rotational motion of the wheel like some watches and torches... that would be so much better than the current 1-use disposable units...

well tbh id take a chance trying to replace the Battery as the tpms is linked to the car. plus id try the folder clip see if that works then put it somewhere safe in the boot in a box keep it safe and dry

Update on the TPMS warning light permanently on:

I booked my vehicle into the Toyota dealership for them to check the problem out before I got the MOT done and they found all the sensors were fine but several TPMS error codes were stored in the system. Once the Diagnostic Trouble Codes (DTS) were cleared the TPMS light went out and the system reset. 

So that was a relief and no charge for the work by Toyota, so just another benefit for sticking to the Toyota dealership for doing the servicing on my vehicle, in my case anyway.

Will have a look at getting a scanner. 

The 5 year warranty expires this month, but as the Toyota Relax scheme sounds good, I'll continue to get it serviced at the Toyota dealership to extent the warranty each year until its 10 years old.

Toyota service costs seem entirely reasonable.  The whole plan for 3 years is lower than the cost of my first Mercedes service 22 years ago and that at the same chain as my Toyota dealership. 

Even switching my servicing to a father and son specialist, with an older car admittedly, £500 was a good price. 

Admittedly, the dealership is only as good as the Service department.
