    Today while driving, the TPMS light came on flashing, then went solid. checked the owner's manual, and it says to bring the truck to toyota. obviously, I don't want to deal with a dealer service center, so what do i do? bought the truck in july of this year, no changes to the tires have been made. The weather did just cool down significantly where i live (high 80s-low90s to high 60s), but if this deflated a tire the light wouldn't blink. am i overthinking things here?

    Check the tire pressure then ignore the light. Mines been doing it for years. Just be sure to check ur pressure every now and again to make sure ur all good.

    TPMS are battery powered and at 8-10 years the batteries can start to die and the light may blink due to loosing contact with the sensor reader then feeding this data on.
    Dealer and all tires stores have a TPMS reader/scanner and they can walk past each wheel and see if TPMS is working. Many posts on TPMS function, pressures, resetting, cost etc on this site so just type it in the search at top right.

    Flashing at first then going solid is a sure sign that you have a bad sensor.
    If it's solid all the time, low pressure.

    Correct.
    The replacement sensors I bought (OEM from Toyota) have what looks like a bigger battery so maybe they will last longer?

    If you want to save some money, the Toyota sensors are made by Pacific Industries who supplies Denso and they in turn supply Toyota. They can be found on Amazon. Be aware that the sensors for alloy and steel wheels are different.
    $36 Denso 550-0103 TPMS 315-MHZ Sensor for Toyota/Lexus with Factory Alloy Wheel Options. (THIS SENSOR MUST BE PROGRAMMED BEFORE USE)

    FWIW - I just went through this issue and it was two (2) bad sensor's. You can have a tire shop detect which sensor(s) are bad (Discount Tire for example).If you go to a tire shop, have them double check the spare tire as some 2nd Gen's came with a sensor in the spare. Mine did not as I found out while diagnosing my issue. Mine is a 2011 SR5 4x4. I am no longer on stock wheels or tires.

    Second Generation Tacoma 05-15 TPMS Light On and Blinking


    If TPMS light flashing then solid, make sure to go professional tire shop and ask service person to check all tire sensors and the spare is working properly with correct inflation psi usually located inside driver side door flange. If sensor needs replacement or battery price range is around $50-$75 each. Check TPMS light again, if light does not reset tire professional service person has a device to re-learn tire sensors to communicate with computer chip. Check tire light again, if sensor is still blinking service person must connect OBD to input port usually under the dash and allow computer to communicate with tire sensors. If you buy a sensor from a tire shop service professionals are usually happy to perform the pre-mention step. Now my TPMS light is off and working properly.

    I put these in my truck a little over 2 years ago when I was buying new tires. No extra charge to install them at that time. I have used this brand on 2 other vehicles. The oldest one 5 years ago. Never had a problem. I replace mine proactively when I'm buying tires if I feel the new tires will outlast the sensors in the truck. Around 7-10 years is typical, but I've seen some last 12-13 years.

    They are cheap enough and easy enough to replace I don't see the point in waiting for one to go bad.

    Mine, it sometimes blinks and then goes solid and then........overnight the problem will go away. There is a "weak" sensor that reports in to the system when it is in a particular stopped position - clears the false reading - then sometimes days later the fault will reappear. PITA!!!!

    Discount tire fellow told me all of the sensors worked - but I don't think they can tell what the signal strength variance may be.
