Default TPC "Inactive"

My TPC system is inactive. I get a message saying "system learning" but it has been that way for days. I assume I've got a bad/dead sensor but how do you tell which?

All 4 tires show no reading. I've tried resetting between summer and winter settings to no avail.

Got any advice?

I just replaced all 4 tires a few weeks ago and really don't want to pull them all off and remount. I may just live with the idiot lights until I need new tires.

Is their any way to turn off the idiot lights?

Just change all 4 sensors. One or more is likely dead and the others not far behind. Use these which are about 1/4 the cost of oem replacements ($136 - ~$180 for set of 4), just make sure you find the ones for your specific model, take them to a tire shop and have them installed for about $25 per wheel. This is about as easy of a fix as you'll find for anything that can and will go wrong with a Porsche. And, yes, I am told there is a way to disable the system but it's quite complicated ($$) and not many shops will do it since there are legal implications. Also, should you decide to ignore it, eventually chimes will start intermittently ringing, error messages will appear and you will become completely annoyed. GL.

You can disable it with a Durametric Pro and removing the TPMS control module.

The OE Wheels sensors work well, except the ones I got from them are reading 2psi lower than actuals.

I've used them too. No data on longevity but they work for sure.

Just replace the tpms from OEWheels, it cost me $300 to replace and remount my tires. I would order a set from them then have a tire shop mount it.

You don't have to dismount the tire to install sensors, just break the bead on one side, install, rebalance. The tire rack ones work great. The lifespan on sensors in 4-5 yrs.

I'm guessing that with and 09, I should consider doing this the next time I need new tires? I don't currently have any issues, bar poor accuracy, but it seems like a logical thing to do.

Yes you should. A Durametric will tell you months left on the batteries, if you have it.

Thanks Cam. I have a non-premium cable. I'll check when I get home. Pretty impressive it can tell it by months.

Which sensors do I buy? Turbo's don't seem to be listed and I see multiple listings for 2008 911's (some 433 Mhz and some 315 Mhz)?
