Help needed for tire pressure monitor reset

Just purchased a 2010 tundra and on way home the low tire warning came on steady. OEM wheels and 275/70-R18 Cooper tires half warn out.
Checked pressure and just one on front was a pound low. Aired them all up to 36 pounds (after reading some of your opinions on "tire pressure") Went through steps in owners manual to reset monitor but no luck! Continuous blinking of idiot light. Recommended pressure on door frame is: Front 30# Rear 33#.
Do I need to try the recommended pressure to get the monitor to reset, does anyone know?
Or do I need to call Toyota like it says in the manual for changing tires, ect.?
Should I search for solution?
Thanks. (pictures coming!)

 

Dont know what you have on the dash for tire pressure monitor on that yr. Model.

Since youve set the tires to a starting point i would run the reset again and see if it takes. Perhaps a sensor is going bad. If you have a tire page on your mfd see what all 4 corners are reading.

Do you have techstream? You may be able to see which sensor is erronous via the software.

Try searching a bit more on here and perhaps this topic was beat to death in your trucks generation section.

 

Under the steering column and more to where your knee is, you should see a TPMS reset button ....

 

If the TPMS light blinks continuously after turning the key on (and does so for a minute os so and then comes on steady) it likely means that one or more of the sensors (located in the wheels) is not being received. The reset button under the dash only serves to set the reference pressure for the TPMS ECU. if one of the sensors has been broken, has a worn out battery (rare) or has been replaced by a regular rubber valve stem this will cause the condition you are experiencing.

 

Update: Took into dealer and they replaced one bad sensor in drivers side front wheel. All good now! Thanks to all for the good advice.

 

I'm glad it's fixed!
