Edit: Title should be “Finally fixed my TPMS Concern”.
I think this is a good enough topic to warrant its own thread, rather than tacking into others.

So, after spending about $350 to get the TPMS System fault to go away, I’m very disappointed that such a premium car does not give actual tire pressure. I’m not satisfied with an alert that tells me a tire is dangerously low. I want to know on a regular basis what the actual tire pressure is.

I had the FOBO system installed on several motorcycles and was very happy with it. So, I bought the FOBO Tire 2 Smart system for cars off Amazon, and installed it. It uses little sensor caps installed on the valve stem. These connect via Bluetooth to a little module that monitors the set points, and connects via WiFi to an IOS or Android Device.

It was very easy to set up. There are a bunch of things you can set up, but the most useful for me is, desired set points, low & hi pressure triggers, and high temperature. You can configure what happens when these trigger, but I have it set in my phone to give an audible alert. They take replaceable CR3023 batteries, Thst from my experience on my zhsrkey last about 1 I think this is a good enough topic to warrant its own thread, rather than taking into others.

​​​​​​So for about $150, you can read real-time actual tire pressure and temperature.


The device on Amazons

The tire stem sensor…forgive the brake dust.

The receiver module. Takes AA bateries

What gets displayed on my phone, I have this system on another car thst has ApplePlay, and it displays innApplePlay as well.

Whwts interesting is the tires except right front were being hit by the sun, so the temperature & pressure increased in those tires.

 

Drat..could an admin edit the title from “TOMS” to “TPMS”?

 

Good ole TOM strikes again :P . I don't like him!

 

I installed these Bluetooth 5.0 sensors in the wheels ($30) and use iTPMS app on my iPhone ($5)…it’s compatible with CarPlay so it shows on the screen with Mr12Volt…about $100 for installation at the tire shop…

 

So do these also talk to the OE system to keep it happy, or have you turned off the car’s TPMS?
Wonder how the battery life compares to the original units.

 

I grew tired of the false error notifications and had the OEM system disabled via Autologic awhile ago. I regularly check tire pressure and this is a relatively inexpensive experiment that’s been working well for a few months…battery life was advertised as 3 years…the display on my iPhone shows battery charge…

 

I use they same system as the OP on my motorcycle it displays via blutooth on my phone

 

I think they’re both pretty good…I did try the one that the OP has and it worked very well, app is compatible with CarPlay. I use a touch less car wash that has a track to pull the car through and somehow the sensor on the tire valve got caught and I came out with a broken valve and a flat tire…that’s why I use the internal sensors…fortunately, the car wash shares a parking lot with a tire shop…

 

Wish I had gone that psth when I replaced the dead Oem sensors, to find out the system only declares flat.

 

What sensors are they, and where did you get them?

 

If you search eBay for TPMS sensors Bluetooth 5.0 you will see internal and external options. I just took a look and they are all coming from China so the price went up…

 

Did you have to program the ones you got? Which ones were they?

 

They come with a set of pairing codes. They come with an app but it’s not CarPlay compatible so you get iTPMS app from the Apple store, put the pairing codes in and the sensors will connect…all of those on eBay are the same, just different sellers…make sure it’s Bluetooth 5.0…

 

Forgot that I had started this thread. 🙄
Then my TPMS saved me, and I started this thread. So, I added it here for completeness.

New look for iTPMS with iOS 26 in CarPlay via Mr12Volt.

 

@arenaej do you set the alerts ao you don't need to keep the app on screen? Also I noted the temperature. Is that the air temp in the tire I presume. Still pretty warm. You're prolly out golfing again too. Son of a b....

 

The alerts are set on my phone so no need to keep it on the screen…I had just come home from a pretty aggressive drive while running errands…ambient temperature was about 40 degrees. I think golf is over for a bit😎

 

34 lbs? 37lbs? Really??

 

Not sure what your question is…I try for 33 front, 36 rear…you may not be aware that temperature can affect tire pressure and I’m not perfect like many are…

 

:-) I am very aware. If you try adjusting your tire pressures to spec, may may notice a better "handling and feeling" car.
And for those spirited driving the winding road days, experiment by dropping the pressures 5-7%.

Cheers!
