Valve stem

On the 2023 Tundra TRD Pro, What is the valve stem for in the bed of truck. Is located in same spot as the electric outlet.

 

Look in the manual.....doesn't the 3rd gen have an air suspension in the rear?

 

Did you get truck used? Sounds like aftermarket air bag helper spring. A schrader valve to fill up when towing.

 

Can you post a picture of valve stem and area above rear axle near coil spring?

 

That’s not oem. Look under truck for air bags.

 

I'll check. Bought used 4 days ago. First time toyota buyer, so still learning the truck. Enjoying it though so far.

 

Finally got underneath. I found the hose but it's connected to nothing. Looks like was cut from whatever it went to.

 

It was most likely to helper air bags.
