There's one on eBay at the moment with less than a day to go sat at £30 with no bids. So I might buy that anyway, even if it's only so I can clean up the body of it while it's off the car and just swap them over instead of having the car sat without one fitted while I'm cleaning it.
EDIT: What and where is this cover plate you speak of? And where is the motor, I'm confused about which parts of the TB are motorised, and which bits are just sensors :confused:

Talisker Hope this helps.
It's a real shame the bahamut cars workshop manual doesn't seem to be online anymore.
Are you sure? I was on it last week. It will not work in some browsers. Internet Explorer is safest, but Firefox should work too.

Just checked the manual at the following link...

I've just tried it with Chrome, Firefox and IE and it only works with IE for some reason.
So they are infact still online luckily

Now from reading that, it points to a bit called the 'limp mode lever' which is attached to the inner wheel on the same part of the TB that the throttle cable attaches to.
The manual states that this is just a mechanical override so the car doesn't become inoperable if the electronic side of things fails.
However the wheel with the 'limp mode lever' is moving just as much as the rest of it on mine, albeit with a slight delay. (as you can see in the video I uploaded) So I don't know whether the electrics have infact failed already and it's just controlling it with the limp mode thing all the time perhaps?

Talisker I'd take the plug off the throttle position sensor and do a resistance check with a multimeter across the outer most pins.
According to the workshop manual you should be getting 1.25-2.35 KiloOhms @ 20degrees C. If you don't get that then the sensor needs replacing.
Just had a go at measuring the resistance, kinda hard because of the way the sensor faces. The multimeter didn't even blink, so I think that means there's no resistance at all (i.e. no link between the terminals at all) Better get a price for a new sensor.

Marsdendean Are you sure you have measured it correctly. I know my multimeter is a pita and has tons of settings. .
Multimeter was on the 'up to 20KiloOhms' setting. next one down only went up to 2KiloOhms so would have been high enough.
But based on the constant buzzing noise the sensor makes I'd be inclined to believe my multimeter. lol
EDIT: ...next one down only went up to 2KiloOhms so wouldn't have been high enough.

Just called Toyota who gave me a price of £102 for the sensor.
So I rushed onto eBay and paid £30 for a whole throttle body which ended at 7 past 5

05-09-2018, 07:43 AM #19It was showing an open circuit. Default figure for the multimeter to display if no connection is detected is '1' which is what it showed.
