Ford Freestar Forum : “I just picked up my 2005 Ford Freestar from the dealership after having the tire...”

What kind of dealer doesn't take care of an issue like that when the car is there? They didn't say anything to you about the light being on?

Try filling the tires up to the recommended tire pressure, if the light doesn't go off you will either need to reset the warning light, or have a dealer look at why the light is staying on.

Thanks!  They also didn't give me a manual for the van AND they didn't do the state inspection!!

Hello, I had the same problem with my low pressure light being on. Only mine was after I had put new tires on. I didn't have the dealer do it and the company I went to had no idea why it was on. They put new valve stems on and everything. I finally called my dealer and they said they would have to reset the light.

Apparently what happened, is that much like a Hummer, my Freestar tires and likely yours as well, have a sensor on them that tells when the tire is low or something has changed. When the tires are replaced or low on air, the light goes on and you have to have them service it. Putting air in the tires is not always going to work. My dealer charged me a small fee to reset the computer sensor and I then replaced the tires at the dealer the next time. Fun huh? Makes you realise how much you actually miss the older cars that didn't have all the bells and whistles, doesn't it?

I hope this helps, although I'm really hoping that your dealer just had a new person that didn't really pay attention to these details and no one was there to inspect their work. As this is really a simple item, but could be very costly as well. If I was you, I would contact the dealer and tell them how upset you are.

These vans use the wheel speed sensors to monitor the revolutions of each tire so if one moves faster than the others (low
air pressure will make that one tire roll faster to cover the same distance as the others) it will trigger the light. Also the light
can be tripped by any dramatic change in the revolutions so if you had a rotation the tread depth difference of the tires on
the front that are now on the back could have set it off (or vice versa) because the rolling circumferences are different or
maybe if they filled the tires up with air that too will change the rolling circumference.

I personally have one of these vans and the light has gone off while driving on a snow covered road for about 20 miles. I am
guessing that the front tires were spinning while blasting through the drifts that set it off. the first time i stopped and checked
the pressures and it was all good, the second time i just kept going since the van didn't drive any different and i have years in
the tire/car industry and would know if i got a flat.

To reset the light just hold the odometer/trip reset button until it goes off, then as you drive the tire monitor will start learning
again the tire rotations until the next time you get work done. Good Luck!
