With and without "Mesage Center" respectively (pretty sure)
With the engine on...
Push "Setup" button, until your driver display says something like "Press Reset for system check".
Then push Reset. The system check will start, rotating through a series of checks.
About the fifth or sixth check will be the tire pressure. The system will sound the tone (same one that starts w/the light) and It'll say something like "Check Tires Pressure" on that moment press and hold for 3 or 4 seconds Reset. When you release the Reset button It'll show "Hold Reset if tires are OK". While that's up, hold the Reset button. After 3 or 4 seconds, the tire warning light will blink 2 or 3 times and then will stop .You need to be ready for it, because you don't get very long to release.
How to reset the low tire pressure warning if the vehicle does not have the "Message Center"
Turn the ignition to the ON position, depress and Trip/odometer button (located in the instrument cluster) until "TIRE RESET" or "CHECK TIRE AND RESET" is displayed in the odometer display window. Once "TIRE RESET" or "CHECK TIRE AND RESET" is displayed, press and hold the button for three seconds. The low tire warning indicator light will flash three times as the low tire warning system begins to initialize.
The TPMS is a pain in the you know what. Have you changed tire sizes? There could be a bad sensor and may need replaced. We continually get problems all the time with the TPMS. We have reset then they reset again.
1. check and make sure that your tires are inflated to the correct pressure
2. turn the ignition switch to the ON position. If the low tire
pressure warning light comes on, push and hold the tire pressure
warning reset switch (think the switch is in the glovebox, but not sure) until the warning light turns
off and then release the switch.
3. now press and hold the tire pressure warning reset switch until the low tire pressure warning light blinks three times.
4. initialization is *not* completed until driving at the vehicle speed
of 19 mph or over for more than one hour. the tire pressure monitoring
starts when initialization is completed.
As for the ABS light, that means your antilock brake system has detected an issue such as a block sensor, or a faulty relay, etc.. when this light is on, it means that your abs may not engage when it should, or may engage when it shouldn't.
1. check and make sure that your tires are inflated to the correct pressure
2. turn the ignition switch to the ON position. If the low tire
pressure warning light comes on, push and hold the tire pressure
warning reset switch (think the switch is in the glovebox, but not sure) until the warning light turns
off and then release the switch.

to reset the tire pressure light.. the light will blink tire pressure.. well what you do is heck your tires make sure they are all to pressure of tire . then hold in on the tire pressure button for the count of 4 to 5 sec. and it will reset its selfs.
You have to "Teach" the tire sensors to the correct pressure. The 02 Sienna does not measure the actual PSI tire pressures, it measures the RPM of the tires. with the tires set to specs, the rotation RPM is "x". If a tire goes low, the rotation RPM would bt "y", and that will light the light.
The proceedure: Set the tires to specs with a known good pressure gauge. The ones that you can put in your pocket, that looks like a pen, are alway sincorrect. Get one with a needle reading. Set the tires correctly. Now, press the reset button, hold it until the light blinks 3 times. Drop it into gear, and DRIVE IT. 8-12 miles, above 19 MPH, and UNDER 61 MPH. This will re-teach the ABS computer the correct values.
if the blinking light looks a cross section of a tire with a exclamation mark in it almost like this (_!_) it is just about the only one that blinks. its tire pressure light chk your air in all tires
