Fuel Gauge stuck on full in 2020 Tacoma

Hi,

My fuel gauge is stuck on full in my 2020 Tacoma and is not moving. I am probably just outside the warranty, which sucks. Only 19,000 Km but just over 36 months. I see some newer Tundra’s are having this issue and thrust is a calibration issue. My distance till empty is counting down but it is showing a lower driving distance when the tank is filled.

I hope it isn’t a sending initial unit as that is costly.

Any thoughts?

 

first thing to check is; see if your truck falls under the fuel pump recall. I can't remember the years it spanned, I know my 2019 was cause I had it done.

 

Most likely.
some say removing the bed is easier then dropping the tank to get at the sending unit.

do what @Chew said first

 

maybe you're just getting really good gas mileage.

 

How long has it been like this. My old truck if you had the key on it would stick it on full for a while then return to normal. Didn’t like me filling the tank with the key on engine off. Just a thought

 

You’re very likely in the fuel pump recall group, I’d look into it. Fuel sensor is on the pump itself and they replace the whole assembly with the recall.

 

Infinite gasoline glitch!

 

Car companies hate him. Governments want him silenced. Gas stations are scared to death. It’s… infinite MPG man.

 

Gazillion mpg

 

I wish. A heavy duty mechanic friend of mine suggested I disconnect the battery for a hour and see if that resets it.

 

I searched by VIN and I don’t appear to be. According to my VIN there are no outstanding recalls.

Or is this a hidden recall?

 

why an hour? couldnt you just disconnect and then cycle the key to drain the system?

 

Resetting battery power definitely reset my fuel gauge, I am happy I didn’t go the expensive route of trusting a dealership to solve this. I only disconnected the battery a few minutes.

 

I had this happen a couple of months ago. I don't drive my truck much and I think that may have been my issue. A bottle of fuel system cleaner did the trick in about 10 minutes of driving.

 

My truck is a low mileage vehicle too.

 

WOW! i guess with these 3rd gens when something goes wrong do just like you would with a TV or Computer, unplug and plug back in.
