Need heeeeeeelp on C5 TPMS magnet for reprogramming


Hi I have just had my 2001 TPMS sensors renewed and need to program in the new ones. Not urgent I thought but driving back from the tyre shop yesterday the beast clearly thought I had 4 flat tyres, implemented reduce mobility mode and limited me to 55mph - so more urgent than I thought!

Just spent two hours going around in circles on the Net trying to find a magnet.


Does anyone know where I can get a suitable magnet?


I found several including the "real" tool from the GM tools website but none ship outside of US. Nothing on Amazon that looked right apart from the Schrader 20143 TPMS magnet but that is "not available/don't know when". Maplins have loads but they are all small things. Hardly big enough to grab with your forefinger and thumb. Driving me crazy.

I did find some Chinese electronic kits which included the large looking circular magnets with a hole in the middle which was what I was expecting to find easily but the electronic kits are ridiculously expensive just for a magnet.

Try these people:

I bought a neodymium disc and, boy, does it grip! Need a small pry bar to get it off anything ferrous! That was the good news - the bad news was the modules have given up the ghost following wheel re-furb. Just bought new modules - hope they work... Willy

Good luck with yours

Wow brilliant, they have a lot! Do you recall the specs of the one that you chose, i.e. works! E.G. I have no idea of what load I need. I have measured the valve stem width and that suggests a +8mm hole in the magnet.

... sorry the above should read "pull", not "load"

Re: Need heeeeeeelp on C5 TPMS magnet for reprogramming


Sometimes people have luck with small magnets and others need something more powerful. I don't know why this is unless it's due to the make/design of the sensors. When I fitted mine I used an old speaker magnet, quite small but did the job without any issues. You could even pick something up at the local pound shop that does the trick.

Re: Need heeeeeeelp on C5 TPMS magnet for reprogramming


Lol, well what did I have in the hallway awaiting a trip to the dump? A couple of old speakers. Pulled the magnet, presented it to the valve stem, horn went beep Cloud9 Job done, thanks guys.

It was weird though. A couple of months back I pulled the sensor from the rear left and fitted an ordinary valve. Nothing out of the ordinary except service tpms warning message and no pressure reading for that wheel.
Then on Friday I had the tyre shop fit a new sensor to the rear left and new sensors to the front wheels (the sensor on the rear right wheel was renewed several years back).

Driving away I was confronted with not only with service tpms system, but also left front tyre flat, reduced mobility, reduced max speed 55mph. The rear right wheel that had not been touched was showing correct pressure.

Even weirder I popped out this morning before resolving the magnet and popped up to 80mph on the dual carriageway even though the DIC was telling me 55mph!

It is clear that sensors and IT fitted to all cars (well at least Corvettes and BMWs) are not the most robust or reliable bits of technology designed by auto engineers. Hell we have been driving my wife's BMW for 4 or 5 years now with the engine check light on. I got tired with paying BMW 100-150 to just plug their computer in given whatever they did they could not fix it. I said Jen "Look its starts first time every time time, you cannot hear it on tick-over, there are no weird sounds or knocks, it passes emissions every year, it runs as smooth as your bum (I removed babies from that in case of paedophilic accusations but I suppose these days I will get done for sexual harassment), nothing untoward out of the exhaust and fuel consumption and engine temp the same as they always were - wots to worry about, it is a duff sensor somewhere"
