Good afternoon guys, does anyone know if the batteries can be replaced on the tire pressure sensors and what size battery they take?
Thank you

 

No, they are sealed. Need to install new sensors.

 

thank you

 

I noticed the sensors are a ford part. anyone know the part number 2009 XK

 

Any sensor with 315 MhZ. Most member here use VDO Siemens, although those have been.... uh........ something. Name change? Different part #? I can't remember exactly. Any quality 315 will work though. The UK and some other place use 433 MhZ, but those are WAY less obtainable in the U.S.

 

Not just any TPMS sensor will work even if correct 315 Mhz. VDO, Schrader and Continental did not work. Been through this twice. Jaguar had to replace one on my 13 XKR. NTB had to try 3 sensors last time to get one that works. One they ordered would not code. Randomly found one in their stock that did work. The one I bought is still in the box. Best to let a tire store do it. I suppose you could buy your own programmer and try.
There is a disable module sold on ebay. But for Ford, so don't know if it would work on Jaguar.

 

No programmer is necessary, and if some you got did not work, then those were faulty. I'm sure there is a quality deal going on, but a transmitter transmits. That's their job.
Also, no programmer is necessary with these cars. They auto-learn within 20 miles.

 

How long do the battery’s last. My car is a 2008 xkr and has 16,000 miles on it. my dad hasn’t driven it since 2015 and now I have it on the road this year and I get a light but pressure is good

 

You probably need new units. Life expectancy is 5-12 years, with an average of 7. Any tire shop should be able to read the battery status, and will probably find one or more failing units. You’re due for some new tires (based on age), so may as well replace all the TPMS units at the same time.

 

Never buy closeout TPMS sensors. They're cheap for a reason - they've been sitting on the retailer's shelf for years and there's not much battery left.

If an installer tells you that he needs to program the sensors, run - don't walk - away. He's incompetent and trying to rip you off. Drive around for 10 minutes or less and they'll work. It's also a good idea to test each sensor's battery before it's installed using a TPMS battery scan tool.
