I believe that it senses the drag from the flat tire through the axials. Try release some (1/3) of the air from one tire (rear)then drive for about 10 minutes, upto 40mph speed and see if the light goes on. I had a nail in the tire and both times it did indicated that the tire is low on air. Note, the light goes on after you driven.
I'm not an expert on this, but I think that it uses the ABS system, and measures the numbers of revolutions of each tire. If one tire is spinning faster that the other 3, it must have less air (or you are making a lot of left hand turns).
it does work by reading the abs sensors and turning on the light when one wheel is moving faster than the others. however it cannot detect which tire because it actually compares the average of the 2 front sensors to the average of the 2 rear sensors. this eliminates the possibility of error based on a car that is turning one direction or the other for an extended period of time. you know it wont work if the abs light is also on because that would preclude the pressure sensing system from working. otherwise, start by making sure the pressures are correct for all 4 tires( the spare doesnt matter for this van) then turn the key on, locate the tire pressure light reset button on the dash to the left of and below the steering wheel. hold the button down until the low pressure light flashes 3 times. if it doesn't flash but only goes out, turn the key off then on again and hold the button until it flashes 3 times. if it does not flash, there is something wrong and it needs to be checked by a dealer.
Nope on all three. I just topped the rear tires while the vehicle was idling and the sensor went out while I was adding air. Both rear tires were at 32 and I filled them to 36 on a cold day. Front tires were already at 36.
NOPE to all four, and even the last " " did not the original question. The 1st three people sounded like they were literally guessing and have no clue...if you don't know....do not give bad information.
1. Where is the tire pressure sensor located for a Toyota Sienna: The actual sensors are integrated into the valve stems, the small valave where you add air to your tires. You have to remove the tire from the rim seatinig bead and replace the whole valve stem assembly if they go bad with an EXACT part number. They record the pressure inside the tire and wheel assembly and talk back to the vehicles computer using specific frequencies.
2. And how do you determine if it is gone bad? The biggest reason for them to stop working is that they get damaged during a tire swap or removal. You can have the vehicle scanned to usually show the faults. A used sensor can usually be bought for $20-40. If your receiveing side of the computer/body module is good and your tire pressure is per specification, that sensor is bad. Look in your owners manual and set all your tires to the reccomended mean pressure. Once your pressures have been set most Toyota's have a reset button (Avalon is under the drivers knee area, so are most Sienna's but I did not see a year stated) or try disconnecting the battery for 60 seconds. Turn your key to accesory position amd push reset button for about 5 seconds to reset (engine should not be running). Sometimes it takes a few minutes of driving to fully reset and remove the warning light. There is usually a good YouTube video showing the exact procedure as each make and model are different
