intermittent TPMS issue, anyone in SoCAL have TIS??

I have a 2015 Tacoma and whenever I go on a long road trip my TPMS blinks and then changes to a solid light and goes off. This started happening recently during long road trips.

I went to American Tire, they scanned my tires and 3 tires gave a green signal and 1 tire gave a red signal. Their scanner is a cheap one that does not give any battery voltage information.

I bought a TPMS sensor from the dealer and went back to American Tire and they scanned my tires again and all sensors are fine now (all green lights)... damn...

This does not make sense because a week prior my TPMS light was flashing for a few minutes, went to solid, then turned off...

So, I believe one sensor battery voltage is low and the only way to check the voltage is from a Toyota Techstream.

Anyone in So Cal area (Orange County) have TIS that can help me scan the truck?

 

Sensors typically last 7-8 years although in some cases have been known to last much longer. Your truck is right at 7 years old and it wouldn't be unusual for the batteries to start dying at that point. I'd replace them all if one is going bad.

If you're close to needing new tires anyway I'd just deal with the light coming on for a while. You can buy new sensors on Amazon for about $20 each. Take them with you when you have tires mounted the next time and there should be no extra charge to install them. Otherwise you'll have to pay to have them installed plus the cost of the sensors.

 

My tires still have 3 years or so left, also all my previous vehicles I never had to replace a sensor. My 2009 4runner that I sold 2 years ago all sensors were fine. My 2012 Honda CRV, original sensors still good (almost 10 year old car).

I believe its just one sensor giving me trouble, I do not want to replace all 4 yet. I want to replace the one that is giving me trouble. I bought an OEM sensor already so I want to stick with OEM and not aftermarket.

I just need someone near me with TIS so I can check the voltages since the aftermarket TPMS readers just give a "battery ok" signal which is insufficient for my case.
