Since purchasing my 2008 GTR my tyre pressure sensors have never worked (just a dash on the display). It has never particularly bothered me but after going through some of the paperwork i noticed on some old invoices that the previous owner had the sensors removed from tyres... again I'm not that bothered that they are gone but i cant understand why someone would want to remove them? are they that expensive to change batteries or do they add to the cost of replacement tyres?
Thanks
If they are removed completely, or completely flat you get the blank reading you have.
If they are in place with low batteries, you get the persistent flashing readout of 'TPS low battery' which obscures all your other information while it is flashing 'on'
Main dealer will charge for new TPS sensors and coding to your bike, but you can buy suitable batteries with soldering tabs and replace them yourself.
However, if your sensors are missing, it is not cheap to replace them.
There are some second hand ones on ebay, but they are in the US and they operate on a different frequency to UK models so cannot be programmed to your UK bike..
They don't add to the tyre cost, as they sit on the valve stem inside the rim, but there were stories early on of ham fisted tyre fitters breaking the sender unit when removing tyres.
UK ones operate on 434Mhz, US ones on 315Mhz. UK ones are CE marked, US ones are FCC [Federal Communications Commission] marked. Part numbers are different, but they can change even for the same country where the old part is superseded.
If the bike's battery is disconnected for a few minutes, at next start-up the -- -- will be gone.
You can buy the kit below and use the whole thing or if you prefer to put it back to stock you will have to get a dealer with KDS3 to program the sensor to your bike's ECU (if they know how to do it) - just photograph the label on the sensors and note which sensor went into which wheel. They are the original LDL sensors supplied to Kaw. The kit also has the marvellous rt angle valve stems which makes inflation so easy without the risk of snapping the straight stem off as happens occasionally. And sensors do still get broken by ignorant tyre fitters.

EDIT- I have discovered that the 434 sensors in this kit will not function as LDL changed the baud rate so they wouldn't work on the GTR, apparently after Kaw dropped em as their supplier.
Assuming the original sensors are in place, they can be removed and new batteries fitted. I did mine at front and rear tire changes. Mine never flat lined, though. They complained of low batteries during colder weather instead.
I have an old invoice in the paperwork i was given that shows the sensors were removed when they had new tyres. Just seemed strange to me...
Just out of interest, both my tpm's were changed as part of some other work by a Kawasaki dealer (Frasers, Gloucester) and the cost for those two items was £266.00...
The newer sensors aren't amenable to having their batteries replaced as far as I know.
just got a quote from dealer a s I am getting the "low battery warning" £185 per sensor--£42 fitting per wheel and £45 to re-code a lot of money to fork out every 3-5 years just because a £2 battery is dead
Is this the new sort of sensor?
The old one was a doddle, you never had to actually take the tyre off if you had the stuff to compress the tyre itself.
As for the new ones they had a battery fitted sometime, so somehow they must come apart, you may break the cover but surely trying before you lay out hard cash for a new one has to be the way to go.
Send it to me, I will get inside somehow.

To answer your question, Kawasaki decided to make them sealed so that the battery isn't easily changeable. Cost to replace about £130 each. There's a YouTube video showing how to take it apart and replace the battery for £2 each. Most people don't bother. The message goes away once the battery is dead. Then just use a tyre gauge.

yes the new sensor it is on a 13 reg local dealer has removed them with the intension of changing batteries rang me up to say he has split one but the battery is welded in the case and is coated in a laquer
Alternative now available to the stock sensors.

After about 2yrs of putting up with the usual TPMS low battery warnings from both tyres I finally visited MOT a Bike in Colchester where they replaced the batteries and all works well, very impressed. All for £90, ride in - ride out service !!
Would recommend them for this simple fix.
Also get my R1 and DRZ mots done there.
Cheers, Colin. :clap: :banana:

was this done with the readily changeable or sealed battery version? Thanks
They were the sealed battery version.
Guys just cut the battery wires and re soldered them etc.
Still working perfectly!!
Cheers,
