This noise happens when im in accessory mode and while the engine is on. It affects my calls as the person im talking to can hear the noise on their end. Does anyone know where its coming from and how to fix? Tried unplugging the dcm fuse but no luck.

Mine has it too for a short while. I believe it's part of the fuel system return that runs to clear things.

Sounds like the EVAP purge system. After my Toyotas are off sometimes they'll randomly make that sound for a few minutes.


Is this sound on all the time when in Accessory mode or while the engine is on? What year is your Tacoma?

All the time as frequently or 24/7?

There was a fuel pump recall. Check to see if your VIN is affected. Also check the gas cap. Make sure it's clicked on well. If it's a leak or malfunction, it might be triggering the EVAP to keep trying to pressurize.

That's what I think it is. I'd say let the dealer take care of it.
