Purpose/ Importance of the throttle sensor...

[no_8wire]

How important is it to have your sensor correctly placed/ have one at all?

Does it have much effect on fuel system?

If you dont have one it will throw a code 7. It tells the ecu what position the throttle is at, so would affect mixture I assume.

[Mr Revhead]

limp mode!

if its a s/c verson then no boost!

so yes, you need it and its important

[no_8wire]

so it is important to have it at the right postsion then...hmm ok...thanks

pretty easy to setup if yours is out, I have the specs if you dont have...
(I see Ive been bet to it)

or are you doing something else non standard?

[mr30%jr]

no8 go into clubaw go to links to good info then click on the link i posted and have a read about toyota ecu input sensors

it will tell you exactly what a tps does and why its important

[no_8wire]

non standard... I am going to play with that idea I had about the double throttle bodies...I know it prob will have no benifit but I want to give it a go.

so some how I need to change the sensor postion so at half throttle it is sensing full throttle. I have the orignal settings for the bluetop but not the red top...

[Ae92typeX]

perhaps you could gear it at a 1-2 ratio
but, in using a twin throttle, wont you want it so you can wide open both also? (cant remember all the parts of you other post sorry)

WHY???

Even if you are contemplating twin Throttle body's you wont need to do this.

It measures pedal position as much as anything.

well I thought that since at half throttle( with the double TB) it will be the same amount of air as full throttle with one TB...I would need to adjust the sensor to that this in to account...

[Mr Revhead]

only if the TB was the restriction in ya airflow....

if its not the engine will still suck the same amount of air.


to be honest i really do think your on the wrong track for a stock engine

[no_8wire]

I know Im just playing around...I start work in mid jan so I have a lot of free time...
Its giving me something to do...just like the hood and lid mods that im doing..

[Mr Revhead]

ok

then what id do is just hook up one TPS. itll still tell it where 1/4 1/2 and full throttle is. and itll only suck in the air it needs. and seeing as its MAP sensor it measures the air in the manifold....
