Tpms evaluation

What analyzer should I use

 

Can you clarify your question?

 

Is your TPMS light on and you're just trying to figure out which sensor is bad?

 

I learned mine is the 1st and 3rd from a diagnostic tool but I don’t know how to tell which that is so I’d just replace them all. Discount tire does it.

 

I have an '04, which will only tell you that you either have a low tire or you have a bad sensor. If any sensor is bad you want to replace all of them or you'll be chasing sensors.

If it's flashing you can find out which sensor is bad. Start with the first tire and let out about 5 lbs. If the flashing stops and the light is solid, that one is working. Air it back to normal and go to the next tire. When you lower the pressure 5 lbs. and it continues to flash, that's a bad sensor.

I bought an Autel MaxiTPMS

$219 TS501 PRO TPMS Programming Tool, Same as TS508, 2024 TPMS Relearn Tool Newer of TS501 TS408S, Activate Relearn 99% Sensors, Program Autel MX-Sensors [315/433MHz], TPMS Reset/Diagnosis

TS501 reader and 5 Denso sensors off Amazon and paid the tire dealer to install them. I took it home and programmed them myself; easy peasy. I paid $200 for the Autel and $33.60 each for the Denso sensors. It was still a lot cheaper than paying a dealership and now I use the Autel to find the low tire and also to check the sensor battery and tire temp. It's a handy tool.
