How do you fit a gen 3 tps sensor?
 
My old one broke and i have my new one, now i can get it to fit like the last one?
 
Any special techniques?
 
Cheers

Is the TPS sensor when moved supposed to open/close the butterflys to let air in?

No it controls voltage to the ecu etc

Well not quite sure what happened with my old tps because if i moved it up it opened the butterfly. Not by much but a noticable amount.

I do recall it\'s attached to the same rod as the secondary butterflies but I haven\'t had one apart for a few years. It needs setting between a specific voltage range

If you\'ve got the fsm, it\'s in there

that things are supposed to be a nightmare to set up right, so be patient

If im really honest i just want somewhere to start ha ha.
All ive done is placed the sensor on the TB and put the screws in. Ive made sure its facing the right way but thats it. Ive not tightened anything up as i want it to move to i can get the voltage right.
 
I just simply cant get the car started as not enough air getting into chamber i dont think.
 
Should the car be able to start with the butterflies nearly closed on the TB?

Ifs not within the require parameters the car may think it\'s on full throttle so won\'t start as its trying to pump in lots of fuel. Use the apexi controller to check the values

Funny you should say that as each time i try to start it smells like pure unleaded coming out of the exhaust.
 
Ill check the apexi next time to see if it can give me a visual aid

it wont throw up an error you just need to find the voltage readings it needs to be within and set it to that by turning the TPS and screwing it into that position.

You have to spin the tps so it connects with the 2 lugs before bolting it up
Title: TPS Help
Post by: Mikey22 on May 10, 2012, 01:12:47 PM
Thanks for all your help. Must admit i didnt spin the tps so that could be why its not firing up. Last time i spun it must have done it too far as when i went to bolt it up it opened the throttle.
 
Its a little picky this one ha ha

From memory if you start with the tps at 12 o clock then rotate it towards the passenger side you should feel it come under some tension where you will be able to bolt it up.

Cheers Jay, I\'ll take off the TB and give it a try tonight. So there should only be a 90 degree turn.

Post by: JayDee on May 10, 2012, 01:39:54 PM
I only said start at 12 so you do not miss the lugs, when you take it off you will see what I mean.

Post by: Mikey22 on May 10, 2012, 01:47:09 PM
yeah i think i know what you mean, I always got confused at to which way to turn it. Not sure if it should wind up the spring when opens or unwind it. when the plastic bit inside is twisted i mean.

Post by: JayDee on May 10, 2012, 02:06:07 PM
Unwind it I think although never really took notice,do you have a pfc

That\'s good it will be easy to setup

I wish i could say that jaydee ha ha. I had a quick look last night but typical scotland it was chucking it down so was only in the car a few minutes.
 
I take it you need to be in the \'etc\' section on the apexi?
Then sensor check?
Title: TPS Help
Post by: JayDee on May 11, 2012, 09:23:36 AM
Yep that\'s the one, do you know the what the values should be?

If im honest no not yet. However i know that FD3s.net has values on there.
 
I\'ve been on the sensor check before. I know that there are values down the left hand side, then there are like tick box circles on the right.
 
I take it the values i need to be looking at are somewhere on the left hand side ha ha. Just hope weather is better tonight so i can go have a play with it.

I think tps 1 should be around 0.7-0.8

Vta1 .25 to .75
Vta2 .76 to 1.25
Make sure your cold start is off and idle speed is correct.
How did you get on?

Hey guys thanks for all ur help, got the sensor on and got reading one within in range. sruggling a bit with second range. it now starts but has a bouncing idle :( not good.
Title: TPS Help
Post by: Mikey22 on May 14, 2012, 10:18:54 AM
Just a quick question as not 100% sure and its kinda on topic lol
 
If my exhaust was blowing from one of the gaskets would this cause a bouncing idle?
 
Im just trying to trace down the cause of this, however i know it could be many things such as
 
Plugs
plug leads
coil pack
vac leak
TPS
etc etc.....
 
I\'ve looked at vac leaks and checked plugs are ok, just not checked coil packs or plug leads but they seems to be working fine.
 
Thanks
