Hi Garry I'm having the same issue. Has this been resolved? -
By Dazzler300 · Posted
Any mechanics or owner here that have done the sparkplugs on a V6 in the 2019 Hiace Van new gen(300). I,m a competent mechanic (Fitter and Turner in Hydraulics) and was hoping to do them myself, however after downloading the Workshop manual files it appears that after removing the throttle body and then reinstalling it (after plug swap) the TB needs to be "recalibrated". Question is, can the TB be recalibrated after i change the plugs or will the van be undriveable until the dealer plugs in and recalibrates. I really wanted to do the job myself and save 600 bucks. -

Hi, New member here 2020 Sahara (55K on clock) reversing camera has just stopped working after completing a 4,500km trip on 99.9% bitumen, for unknown reasons. All other cameras are working and I am currently searching to see if there is a blown fuse but having difficulty. Has anyone experienced this or can point me in the right direction please, even as to where a fuse might be located? I even searched google that advised that the fuse number etc is listed in the owners manual but no such luck. Tried YouTube vids of how to get into diagnostics to no avail & tearing my hair out. The photo shows what is on the screen and if I press the camera view button, nothing happens but if I touch the screen in the lower RH corner graphic, the overhead view disappears but I have an information triangle that I cannot work out. -
The problem is in the venturi sucking mechanism that pulls fuel from the sub tank to the main tank. Diesel 120 prados have a small sub tank (approx 35L) and a big main or front tank(145L). 150 Prados have similar but smaller tanks, 150L total To understand everything you have described you need to understand how the system works. This write up is for the 120, but from what i know with the 150s the system is the same The fuel pump is located in the front tank and pumps fuel out and through a fuel filter that's located underneath the car next to the tank and straight back into the same tank. When it comes back into the fuel tank module there is a venturi or sucking mechanism that "pulls" fuel from the rear tank to the front. If this venturi is blocked or cracked than the fuel isn't transferred. Common cause of this is dirty fuel, not changing the fuel filter underneath the car, If you replace the entire fuel tank module in the front tank then your problem will be fixed. Or get the mechanic to take the fuel module out again and pull the fuel hose's off the venturi on the fuel module and clean it. Fuel fill vacuum lock issue again here how the system works Diesel is sucked into the engine by the injector pump, from the front tank to the engine then back into the rear tank. If the fuel isn't sucked from the rear tank to the front tank (because of the blocked venturi fuel module issue) then the rear tank becomes overfilled and overflows up the fill tube and trickles into the front tank. Providing there's enough fuel in the system (more than 35L) so all good you can keep driving as long as you have at least 35L in the system. If the car runs out of fuel, what's happening is the front tank runs out while there is still fuel in the rear tank. When trying to fill the car the rear tank is already filled to maximum, fuel flows through the fill tube into the front tank, the front tank breather hose goes into the rear tank. but because the rear is full and overflowing the air has nowhere to go and instead bubbles and blows back up the fill pipe, clicking off the bouser, making it difficult to get fuel in. I found that parking the car on a hill nose down a little helps fill alot quicker. The fuel tank module is quite expensive $500 plus, so a backyard fix is to put a cheap ebay inline fuel pump on the hose between the 2 tanks and attach it to a switch inside the car. You can flick this on 10minutes before fueling up at the servo and the car will fill without air lock issues no worries. Obviously cant leave this fuel pump switched on all the time because when the rear tank emptys the pump will suck air and burn out. (Which is the reason Toyota designed this venturi fuel transfer mechanism in the first place) And the fuel gauge obviously doesn't function correctly if the fuel isn't transferred from the rear to the front as designed.
