While driving along today, the Tire Pressure Monitoring Fault light came on with the flashing low tire light on as well. When I got home, all tire pressures are fine. The tire sensors where all changed about 2 years ago with the new correct sensors (Continental VDO) Although the spare on my 2010 has nothing to do with it, I inflated it to 50lbs which was a good idea as it was at 15lbs. I've read tons of horror stories with many issues with this system. I'm really not enthusiastic about approaching this. There are so many threads on this subject. I don't see any real fix and is can be many issues with the monitoring system. I read about letting air out and reinflating which I did when I first got my new sensors installed. It's getting dark now, but I'll look at it again in the morning. I read something about a lose wire behind the front bumper may cause this, and also something under the front inner tire linings. I did have my engine air filters changed a few months ago, and I was fooling around with my Bovee ipod connection for my radio...now that might be getting this thing out of hand! Any suggestions out there? Thanks all.

 

I don't trust or rely on my TPMS, even though I've never had a low pressure warning. I'm old school and still prefer to use a tire pressure gauge, although now it's digital and requires a battery. But it's far more accurate than my antique, battery-free analog pop-up stick gauge. I check my tire pressures whenever I clean my wheels.

What's crazy is that Amazon sells digital tire pressure gauges that talk and tell you the tire pressure! I don't get it. If you can't read the number on the display, you shouldn't be driving!

More important than TPMS or a digital tire pressure gauge is a 12 volt air pump that plugs into your cigarette lighter. Unless you have a catastrophic tire failure, it'll inflate a flat tire so you can drive to a shop and get it fixed. I bought one for all my family members to keep in their cars. It can keep you from getting stranded and waiting hours for help.

 

Just a guess on my part, but assuming the TPMS sensors at each wheel are good, and tires inflated properly, it could be the TPMS receiving module that's probably buried deep inside the dash somewhere. I have the same issue on my Range Rover, i.e. all wheel sensors check OK, including the spare, but the module has failed. Too labor-intrusive and expensive to fix. I check my tire pressures regularly anyway, so a small piece of black tape placed over the flashing TPMS light solved the problem. Not the way I like to solve a car issue, but not worth it to fix.

 

For a time, put a piece of masking tape over the tire icon. It does wonders in helping you ignore it while you take your time to correct the situation, before the trouble disappears.

 

UPDATE: I brought the tire pressures down to 22lbs and then inflated them to 40lbs. I drove for 10-15 minutes and presto! The tire pressure fault message is gone! I was lucky and I hope it stays this way. I'm a happy camper.

 

A flat tire may not hold air for a trip home.

Gave my girls FIX A FLAT for Christmas..

Wifey got one too!!!

 

It seems that if you have the tpms problem, it is a keeper.
I have done everything recommended by individuals and the jag manual --short of replacing receivers, processors or configuring the sensor's numbers.
replaced sensors
replaced antennas
pressure changes up and down
wiring checks
Some day I'll attempt adding the sensor's serial codes.
I have had times where I have no faults for weeks and then I have them everyday, multiple times.
Make a change and all is good for a drive or a day or a week.
I'm old, the challenge to correct this fault is gone, tpms won this one.
When/if I find someone local that will turn off the tpms warning system I'll consider it a win.
Good luck to others.

I carry a squirt bottle of green slime, a can of fix-a-flat, a small halo battery backup/air pump + a 'new' spare + rubber coated screws.

I guess my black beauty heard me, last evening we went out for dinner. 75 mile round trip and no tpms faults. Other than getting in the car and driving I did nothing that would 'cure' the ongoing problem.

I wouldn't get away with that.

 

Some tire manufacturers void their warranty if you use that slime crap. Many tire repair shops will also refuse to work on them. rubber screws and an air pump should get them to a shop, or a AAA card that includes towing.

 

The tire flat fix can get you home or to a shop, but after using the stuff the tire can no longer be repaired properly.

 

Interesting. I think I'll try that with my Range Rover.
Cheers.

 

I have same problem. THe warning comes on sporadically, goes off, comes again 2 days later, etc. I haven't tried the inflation trick. Let us know the outcome.

 

Sporadic... Cabling? Or on the threshold of under inflation? Or a flaky TPMS sensor?
Stating the obvious, you are filling to your preferred pressure when the tire is cold??

 

Brought back to normal pressures and it’s holding up. Did the exact same procedure when I purchased new tires and sensors 3 years ago. Never came back until now. Every 3 years I can handle.

 

So it worked huh? I am going to try that next. Good tip

 

Put 45 psi in all tires and you'll never have to worry about the TPMS warning again.It will just do a hiccup like other cars do from that point on either at a cold start up or driving for quite a while

 

finding the small puncture
may be visibly impossible..

Fix a flat has saved me multiple times

No issues

 

LOL, I haven't had a flat tire since I was 16 years old and had to buy retreads because that's all I could afford. Ah well to each his own. My wife will just call AAA if she ever gets a flat. She's never had one in over 50 years of driving.

 

AAA...hope it works for you! After @ 15 years of membership
I had a flat one evening, called AAA @ 7:30pm, parked on the side of the roadway, waited, waited, waited, called AAA again, waited, got a call back 1.5 hours later stating that there weren't any trucks in the area available and it would be the following morning.
False security!
