Hey guys, I have come here as last resort after browsing the web for hours for this issue.

Here is the case on my 08' 133k KM :
In every long trip after 250 km the TPM starts to act up, dialing back to (---) randomly tires. After the car stops for a while the dial comes back to normal.

But then I felt on a pothole and broke a tire. After replacement. I tried the reset TPM method by using the key remote buttons and now my sensors are all blank (---).

From what I've read, I was suppose to use a tool on each tire to make the reset or ride it out until it is automatically setup. But I don't have the tool nor it has corrected by itself.

I have tried unplugging the battery among other things without success.

Any ideas you guys might have on this I will greatly appreciate it.

Thanks in advance

I'll defer to our Technical Moderator donbrew here, as TPMS issues are a real pain in the butt.

One thing I will say is that the batteries in the sensors are supposed to have a nominal service life of five years, you've got an '08, so the batteries might have pooped out on you.

2006 does not require a tool.
For a Owner Manual that describes the correct procedure follow the link in my sig.

Sounds kind of like you are talking to people that think you have PT Looser.

The batteries may have died, that requires new sensors.

If your 2008 has sat around for a long time with a dead battery the bad news is that the RCDLR may need a firmware update.

It's possible that the law in Panama does not require TPMS. You probably want them to work, but.....

Thanks I donīt know if there's anyone here than can do the work for changing the battery. I am going to dig a little bit to see if it's easily for a DIY project.

We are not required, but it I have grown used to them. and the orange alert on the dashboard is distracting.

Changing the TPMs require dismounting the tires then replacing the entire TPM unit and valve stems. Only DIY if you can mount/dismount balance your own tires.

The valve stems are "special" as they have a threaded end for screwing the sensor on. Many tire shops will try to claim special expensive tools are used for the job, yeah right, a small Philips screw driver does the job great.

If they did work previously and no extended dead/no battery condition, new TPMs should do the job.

Man, I am kinda glad I dont have a TPMS!

It's one of the reasons I searched high and low for the 2007 2.2 I have, no TPMS and no VVT!
That and I wanted the IBM paint!

Thanks guys, as usual you are right on cue. Now I more convince I need to replace them or eliminate them all together.

You'll still have the dash notice if you eliminate them.
