I’ll bet jagtoes bought his for the same reason I bought a reader (without programming capability), because he also has a Lexus.
Those a-holes thought we should bring our cars to the dealer each time we swap wheels (winter/summer), rotate tires, or need to have a sensor changed. The cars don’t relearn new sensor codes by themselves, like our nice Jags. The new codes need to be entered into the car via an OBD2 interface.
I went the route of a reader and a separate car programmer, while jagtoes went the route of a reader with integrated sensor programmer. We accomplish the same thing, just differently (keep the dealer from charging a hundred bucks every time you swap wheels around).

 

As the former owner of a brand new 2007 LS460 with almost every option, I learned the hard way about their "Relentlessness Pursuit of Perfection." I was conned by their propaganda. My 2007 was recalled for defective aluminum fuel rails and 32 defective engine valves, and there were TSBs on wind noise, dashboard rattles, and the main wiring harness just to name a few of the defects. As in the old Packard ads, "Ask the man who owns one. " I learned my lesson. Fool me once. Never again. And all this happened with less than 40K miles. The relentlessly pursuit of my patience. What good is a warranty if they can't fix it? And double their hours from what the TSB specifies when you're out of warranty (time, not mileage) and they refuse to discount the cost or recall it? Thieves. I'll never buy another Toyota product.

 

Ha don't have any neighbors , that's why I buy the tools. Country living .

 

My TPMS sensors on my 2010 XKR are going on and off. The tire pressures are correct. So am I reading this correctly the battery for the car needs replacing?

Your car battery is probably OK. Most likely, it's the batteries in your TPMS sensors in one or more wheels Any tire store should be able to scan them for battery life. They're molded-in and not replaceable, so it's best to replace all 4 at the same time.

Beware of cheap replacement sensors, as they may be new old stock manufactured 5 or more years ago with limited remaining useful battery life.

 

Take that car battery replacement comment with a grain of salt. I think SOV211 has stock in a battery company. The car batteries do need to be maintained but as Stuart noted, its likely the batteries in your sensors. If they are original equipment, they are well past their expected life of 7 years. worth having a tire shop check the signal. they usually don't charge you to do that.

 

I repeat that in this instance, the intermittently appearing TPMS light was the first indication of the need for a new main battery. But a first indication could be any one of many symptoms:random warning lights, touch screen failing to boot up or freezing, top not latching, seats or windows not operating properly...so YES, the main battery may indeed be the cause of this...but the cause could also be in the TPMS units themselves. If your battery is more than 4 years old then the possibility of it being the problem is quite strong. When battery voltage drops, various modules in the car start to display panic symptoms!

 

Sadly, I don't have any battery company stock. But I have had my own experience with a failing battery in an X150 (as noted previously) - and I have witnessed many instances of progressive battery failure in X150 cars (some quite dramatic: flashing turn signals, horn actuation, door windows failing to drop to clear the weatherstrip, roof failing to latch, ABS warning light,...) all with different symptoms and all cured instantly with replacement of the battery by a new and fully charged battery (the important thing here is "fully charged") - so yes, for any electrical issue the main suspect as far as I am concerned is the battery or battery connections. That is not to say that there can be no other cause for failures or for warning lights - but the battery output should be checked before spending a single penny.

 

Well he's only pointing out one concern, but feel free to beat that drum as you do. My previous XK battery was the OEM and bit the dust @ 9 years.

Feff, you can also have your battery tested at a local auto parts store for no charge.

 

I've seen TPMS modules being sold at two frequencies: 315zMHz / 433MHz.
Which is the correct frequency for our cars? Or are the sensors in the wheel wells dual frequency?

 

Mine are 315MHz

 

If you haven't done so, this thread is worth reading from the beginning. There's good advice as to what sensors to buy, what to be wary of, and where to buy them.

 

The arrival of our first "Polar Vortex" yesterday for Winter 2019-2020 brought about three flashing TPMS warnings. I aired up the tires and the TPMS warnings stopped. The tires have been checked for leaks by the installer and they've found no leaks. I'm starting to think it's the seals on the TPMS. Had a similar issue on an Acura. New seals did the trick on the Acura.

Any other repair kit options?

Guys giving you an important 1year update.
I had TPMS warnings every year like clockwork when the weather fluctuates wildly, always in fall or early winter and no other time.
Last year I had enough, flushed the tires and refilled with nitrogen ($20)
Zero problems this year. In fact yesterday was the wildest swing in history.

 

I replaced all 4 sensors in my car this weekend. I was getting the TPMS warnings showing the car and each tire flashing. I figured my car is 12 years old, so time to change the sensors. A few miles on them and boom, the warning lights disappeared. Yay!

Then a different warning appeared a few more miles down the road. It shows a big yellow triangle, rather than the car drawing, and says check the air pressure on all the tires. Then it blinked off. But has reappeared and blinked off several more times.

Any suggestions?

 

When in doubt,



You have nothing to worry about. Your XK is a slow learner. Cheers!

 

Delete - Stuart beat me to it.

 

Thanks!

You would think that since I changed the sensors at a tire place that the pressures would be correct. But I will check them when I get home. Also wonder why the warning comes and goes rather than stay on all the time..

Will report back with my findings.

 

Hi 110reef,
Where did you get your tire pressure sensors and which brand are they?
Also, did you have to program them?
Thanks,
Bob

 

New sensors need no programming. A short drive is all it takes for them to work - 10 minutes above 18 mph. It's amazing what you can learn when you

Anyone who charges you to program them is a thief.
