Tire pressure monitoring system not available...

I just painted my 22" wheels and when I put them back I get this error message. I have tried resetting the system following the instructions in the manual but it is not going way. The monitoring system was working fine with these wheels before so I don't get it. How can I check if the sensors where reinstalled correctly? I don't even know where they are located.

There are sender units inside the wheels that send signals to a receiver module inside the car. Are you sure the people who repainted your wheels replaced the sensor units when remounting the tires. Maybe they forgot and just mounted new valves and forgot the sensors, I suggest giving the shop a call.

I am suspecting this is the case as if the painting had anything to do with it it may be more likely that one had failed and not all of them, unless they were left on the wheels and the paint was baked in a paint oven at about 400 degrees which may also have ruined them.

There are hand-held testers available and you can test the tps sender in each tire by holding the tester near the tire. These are around $500 each but good tire shops or dealers should have one.

Let us know how it turns out.

ok checked all the sensors and they seem fine. No paint on them etc...

The exact message I am getting is "Tire Monitoring system unavailable"


Not sure what could be wrong.

I had these wheels working fine with the sensors. I then replaced them with the stock wheels ( with no sensors on ) while the others were painted. Thats when I started getting the error but I didnt worry about it because the stock wheels didnt have the sensors on. I was sure they would start working again once the other wheels were reinstaled.

Not the case. Is there like a hard reset or something What can I do on the car to make it read the sensors again?

Here is a picture of what a Beru sensor looks like, it is inside the wheel and covered by the tire. If you can "see" something similar to this then your system will not work because the tires are not fitted and there is no air pressure to register.

yeah , I had the tires taken out and saw all four installed. Still I keep getting the same reading...

Not sure what could be wrong. As my previous post says, these sensors were working fine with the aftermarket rims...

Ok the only other thing I remember a tech talking about one time that each sensor on some cars can be location specific. This means that on installation the sensors position on the car is registered to the receiver. I'm not sure if this is the case on Maserati but you may want to call a service department and ask them.

On Beru's website it states that they are the supplier of the Maserati GT sensor and here are some instructions you can download to calibrate them

This is an awesome file to have but I don't see the maserati listed in the manual. Not sure if there is any instructions for the Gt at all. I guess the dealer will fix it on monday. Thanks

It was more for you to understand the problem as there is a list of what causes the "system unavailable".

To reset the system you need to press and hold the calibration button (overhead on the roof) in the car and hold it until the notice on the dashboard says something like "calibrating" . Drive the car around whilst the calibrating is going on, do not turn off as this will not complete the process. It takes a few minutes but can take up to 20.

Yes. I know the procedure to recalibrate it. I have done before. But this time 10 seconds after pressing the button I get the messge : tyre monitoring system not available



I have tried many times and I get the same thing. Hopefully the dealer will know what to do. Thx

I am having the same problem, did anyone come up with a fix for this? I got new tires put on the front of my car and now I am getting the same warning "tyre pressure monitoring unavailable". I had them check the sensors and the computer says that all four tpms sensors are working correctly. I also tried disconnecting the battery to the car but that didn't do anything either. :(

there should be a tpms calibration button on either the dome light module or in the instrument panel menus. activate it holding the button. it'll take 10ish miles at about 60mph to finish.
if that doesn't work, there may be a issue with the new tire construction preventing the sensors/receivers from operating correctly.

Same issue, from my research the TPMS system went thru a major revision during 2009-1010. My car is a 2010 GTS. I've tried the calibrate option many times and also replace the TPMS ECM with no success. I've seen but cannot get confirmation that the TPMS sensors needs to be manually entered into the Car's computer via the dealer. I sure hope you find a resolution.

Whenever this happens it's a trip to the dealer for me to get it reset, the calibration button does nothing.
