TPS Change

[billh]

What is the prodedure for changing the TPS? Is the switch adjustable or does it just bolt on. (The local Ford store actually had one in stock, will wonders never cease!)
Thanks, in advance
Bill

There`s just 2 screws holding it on.When you put it on,you need to "twist" it to get tention from the butterfly shaft.You`ll see what i mean.

Just screws on.

Its the two screws. Use a big screwdriver cause they are on tight.

I stripped mine too. They were just like butter. I pressed as hard as I could with a big screwdriver but they just flaked away.
Then, in using vice grips to take them off, the top one broke the head off it, so I had to drill that one out.
Yup, fun time to be had by all!

Jeremy,
I did not twist anything to my knowledge putting a new one on. It works just fine.
Is there something I missed and did not do right or did I somehow put it on correctly?
As long as it works, I guess I'm not too worried but I don't recall twisting it, just put it straight on.

Would WD-40 or Liquid Wrench help in this matter? I think I may have to change mine as well as I get a light stumble at low revs.

WD-40 won`t help because it won`t get to the threads.I`m suprised to hear it`s difficult because mine came right off.
DIAMEG-you must have gotten lucky and it went on good.If it`s wrong,when you hit the gas,it will die out.It`s basically just making sure the TPS is loaded corectly so it will have tension when the shaft rotates.Maybe i just got unlucky and had mine on the wrong setting.

WD-40 did not help mine. I did not try liquid wrench.

If I were to do it again, I would perhaps try the Liquid Wrench, and would use vice grips along with the screw driver at the same time. That is if you want to try and keep the same screws.

If you use an impact driver to loosen and tighten the screws you will be better off. An impact driver is a steel handled tool that holds different screwdriver bits (phillups, straight, Reed and Prince, Torx etc) You place the bit tip into the screw head and rotate to pretension the driver. Then just tap it firmly with a hammer and the driver convert the forward hammer blow to rotational twist at the exact instant that the bit is driven into the screw head. Works every time. Learned about the tool when I owned Japanese motocycles in the '70s.

They are great tools to have.If you do try one,pull the TB off 1st.Also,be careful since the TB is cast,it isn`t teh strongest thing on the car.

Got it swapped last night. Luckily, it wasn't overly tight. I am reserving judgement, but so far, it seems to have made a difference. My trans problems have all but disappeared. Part throttle shifting is greatly improved.
Thanks everyone.
Bill

 

[Diameg]

Well, I'm certainly glad to hear that everyone else's comes off nice and easy.
That would have been real comforting to me as I drove to Canadian Tire with tape holding mine on to buy some screws to replace the liquified stock ones....

No, good to hear that it worked for you billh.
Funny thing is, mine did not help the problem that I had intended it to fix (poor idle), but the throttle response was greatly improved.
I did not even know I had a problem with throttle response until I changed that doo-dad.

if it makes you feel any better i broke my old tps,on purpose and cut my hands (not on purpose) because the bolts stripped the second i put a screw driver in it. the new one is on but i am havign the same problem still.

 

[SW SHO]

I'm thinking of replacing my TPS now cuz I've had this little dip in rpm right when I press the gas. It's not a dip from idle, just when I first step on the throttle. Clean K&N, new plugs, new fuel filter so I'm guessing this would fix this problem..

Question: where's the best place to buy this part, and what should it cost?

*edit* / I found the part at Autozone.com. It's from Wells replaces part number #9b989-BA.. is this correct?

I got mine at autozone for about $23 or $24. It was cheap, easy to test, and had it in and out in 5 minutes. The screws on mine also appeared to be made out of silly puddy. Nothing a vice grip couldn't fix. Just go to the autozone and take out your old one, then show it to them and they'll get you an exact match.

I learned the hard way about the impact driver after stripping the screws on my daughters ****** and had to use a saw to cut the head of the damn screw off. the impact driver is the correct way to go. For some reason Ford, in its infinite wisdom, puts loctite on the damn screws. Quess they dont want the TPS sensor moving about easily.

That TPS swap really solved a LOT of problems. Best $20.00 I have spent on this car so far.
The reason my TPS swap went so well is that a few months ago, a Ford tech had it off and cleaned it. (At least I paid for a TPS cleaning. Could it be that the only thing cleaned was me?)

I've never heard of a TPS cleaning, (it would be cheaper to replace it), could he have meant the MAF cleaning, thats what the sensor sits on. Sometimes they use the wrong terminology.

The TPS is connected to the throttle body. The throttle body is connected to the TB hose. The TB hose is connected to the MAF. The MAF is connected to the MAF sensor.

So please please please don't tickle my knees.
