I have a 2009 Quattrporte S with 22000 miles. I don't drive the car much. I started it a couple of days ago and noticed the tire pressure warning light was on, I don't know why the first thing I did was push the calibrate button overhead and a message came up that calibration was on, a green light with the tire logo on it came on in the speedometer area for a few seconds and went out. I went to check the tire pressure in the display and they all had no psi reading just 3 dashes. I checked the tire pressure and they were all a couple pounds low so I filled them up and drove the car and pushed the calibrate button a few times but keeps showing no psi and just ---.

Could all the batteries in the TPMS have died together?

Thanks for your help.

You need to drive for a while when the calibrations is taking place. I can't recall the exact distance time but it's *about* 20 minutes or so. You'll need to start it again now you've put some more air in. Eventually it should clear and show you pressures as normal.

1- if its a calibration issue, catman is spot on. it takes about 5-8 miles at about 60mph to calibrate. the calibration stops if the vehicle drops below 10mph or so.
2- it could very well be the sensor batteries, their lifespan is 4-6 years in my experience. if they are low, they may calibrate but can lose calibration again.

Can the batteries on all sensors die at once? when I go to check the psi there are dashes only for all 4 tires.

I really appreciate your help on this. I have the car for sale I want to take care of this before I sell it.

Dear all,
I have a similar question regarding the error messages of the TPMS:
I have a new ECU installed by Maserati, they said everything fine (with the summer tyres).
I could not check on the road myself, as I immediately changed to winter tyres which do not have the sensors.

I thought after calibration the system should recognize that there are no sensors?
Error message now is TPMS failure - go to dealer (take your money with you).
Is it normal or indicating that the system is still not working correctly?

It's a QP Sport GT S (pre facelift) of 3/2008.

Thank's for your help, best from Bavaria,

Alex

Sorry, this was misleading: yes, I changed tyres and rims, the winter kit does not have the sensors.

The question is: Should a correctly working system tolerate this with something like "no air pressure available" or is it always the TPMS failure - go to dealer warning?

Jason, with this type of malfunction/error does it require a Dealer Reset of the error? Or a calibration will clear the error? Does it vary on the TPMS system which errors require a dealer intervention?

If there are no sensors in the wheels, it's always going to throw an error.
