Can you fix tpms yourself?

All my tpms went out at the same time. Came back on once or twice for a short time and now they don’t work at all. I tried the reset button but is there any way I can fix it myself as I’m assuming it’s something in the trucks computer not the sensors because it’s all of them.

 

Could be something simple e.g wiring.

 

A few folks have had TPMS issues. No one that I know was able to fix it without help from the dealer. I believe that the antenna module is in the left C pillar.

 

TPMS randomly failing in the first 5 years is uncommon.

Set the pressures a tad higher for now like 34psi and see if it clears up.

You need a special tool to read the sensors and pressure, minimum 200$ for the tool, then if it is a sensor you need a tire machine to replace it.

 

To diagnose/read tpms, you need $15 OBDII Bluetooth adapter , free OBD Fusion app and $15 for toyota PIDs. 170 can go back to the beer budget or buying Tactrix adapter

Read at the wheel, not the tool. You want to see if the signal is valid.

 

Sensor don't go bad at once. The issue is on tpms module.
The obd app at least will tell you if you can connect to it.
You will save 200 towards the dealer visit if the module or antenna took a dump

 

No bought it used 4 months ago and started having issues maybe a month ago.

 

Thanks I’m going to check this out right now. I have a bafx obd2 bt adapter. I looked for fusion app but it’s 10 bucks I don’t see a free one, still going to give it a shot though. At least I’ll have the app for other stuff.

 

How do you know that all of them are damaged? If one is damaged, none will show as working on the dash. A shop damaged my front passenger side tpms when mounting my 285. Since then the warning light is on, and doesn't show the pressure for any of the tires.

 

I would first disconnect battery for 30 mins and let everything reset.

 

I just installed it on my HU. It is free, but you need to pay for toyota PID for your year truck

 

Interesting. I just assumed because I’ve seen cars that only show 2 or 3. I just can’t see why they wouldn’t show at all if one was out.
