Hi Guys!

I am buying a new set of tires for my 997...Do I need to get any parts related to TPMS so the system continues to work properly? (I am using the same wheels/rims.)

Thanks in advance/Respectfully,

Flea

 

How long since you last changed the TPMS sensors? Batteries won't last more than 4-5 years. Now would be the good time to change the sensors, as batteries cannot be replaced. An expensive proposal, I know....

Not sure....? I bought my 2007 911S Cabriolet used in June of 2011. I don't think my TPMS has been replaced. Car has 30k miles on it. Sounds like I am in the window to have them pulled...

Thanks-Flea

 

they are expensive. I would wait till the batteries die and replace all together. If you take the tires out you will have to pay to get the wheels rebalanced.

 

$400+ but if the exisiting sensors are near the end of their battery life you would save cost of a future dismount/remount/rebalance by replacing the sensors with the new tires.

 

Is there any signs to tell if sensors are near the end of battery life?

 

There are no ways to tell the sensors are close to their end of life. Batteries voltage cannot be measured and most tires mounting shop do not have the receiver/antennae to measure anything transmitted by the sensors.

For certain, you will save money by changing them now, and having the wheels balanced with the new tires and the new sensors. Replacing the tires will force you to balance the wheels, no matter what.

Or you can let the sensors die and live with the pesky (every 30 minutes) messages and red and yellow lights on your dashboard. That is what I am doing now (2006 car). However, these sensors are being replaced as soon as I need to change my tires.

+2. i get that message on my dashboard but I'm going to wait until my tires get worn out. didn't know sensors are that expensive!

 

I thought the PWIS tool could determine battery status - maybe it can just tell if the battery is dead??

 

Thanks for all the feedback guys!!! Since I have a 2007, what are the chances of the TPMS failing the next few months? What is everyones experience? Do they last more than 4-5 years on occasion?

Thanxs-Flea

 

I have a 2007 Cayman S... TPMS sensor(s) just went out this past month... I'm waiting until spring/summer for my next set of tires.. annoying and $400 for the sensors is a rip off

 

Update/question since my last post. Ordered my new tires and they are being delivered in two weeks...Well, when I got home from a trip the other day (car sat for two weeks) I had a TPC INACTIVE MSG and the sensors on my left tires are BOTH blank? Been like that for a week now....also have a TPC inactive system learning MSG that stays on most of the time and when it disappears the TPC INACTIVE reappears.

Ideas? Did my batteries finally fail? Both at same time? Anybody buy the sensors from Tire Rack?

Sorry for all the questions...HELP!

There's only so much time in the TPMS sensors till the battery dies and you need to replace the sensors (non-servicable). So its likely ever few years you need new TPMS sensors.

 

Beru indicates battery life is between 8-10 years? Sensors were still working on my 7 1/2 Boxser when I traded it in. Leave 'em alone until they die.

 

Changing my shoes on Thursday and my sensors are still working on my 07 4S. Hoping they will work till the next set of tires which at that time I'm going to change the sensors no matter what.

Too bad they are so expensive...cost of owning a Porsche.
