I have a 97 f350 PS and it will start up just fine but there is no throttle response. I just replaced the tps and checked the fuses and still nothing. Any ideas what it could be? Thanks

 

If there is absolutely 0 response , it may be the IVS ...

Sometimes they can can be cleaned with contact cleaner & compressed air ...

It will also set a CEL ..

 

Hold off on doing what I recommended .. 10 or so people will come in here soon to correct me ....

Thats how we roll here ...

 

It could be the IVS when you first push the pedal you should hear it click also check the plug on the IVS and make sure you have a good connection

 

Or 10 posters will come here & repeat every thing I just said said....

No need to stir any pot here. There self stirring. and contagious, but this to will pass.

 

Hi there, I was messing with my throttle pedal assembly down there once to adjust a fast idle solenoid cable for the pulling unit on the service rig and ended up with the same problem. It's true that if you dont fully seat the switch at the idle position, it will not rev when you start to roll the pedal into that cam roller. He's right , you should hear a click as soon as you depress the pedal, meaning your coming off of the idle v.s. and fixing to call for some fuel. If the pedal arm or the 90 deg. bend thats there for the switch is just a hair off = no go. It all has to happen like in a credit card width or so. Check it out and good luck, Jay

 

After I broke mine, long story, I had to reach down and click mine once after each start up and it would be fine until I shut it down. WhT I am trying to say is that it only needs to make a connection once

 

Well the ivs clicks when I push the pedel, I'll have to double check the connections

 

Does anyone know where I can get the ivs?

 

I don't think you can buy just the IVS think you have to buy the whole go pedal.

Spray some contact cleaner in the IVS around the button and blow it out with air compressor

 

This is the Manufacturer and P/N for the Ford IVS. It is the actual part made for Ford.
I had purchased all the existed stock before and was told that's it. Now it appears that they have run another batch. They currently have 70 pieces in stock. I would recommend getting one as a spare.

Look here:

You may have to search the P/N, but it is there.

it is just a small limit switch. use a multi meter and check it, is it opening / closing when you press / release the pedal? if not, pull the switch off and check it again. if not, replace it. if it is, then you may have to adjust the little tabs that triggers the switch.

 

its possable they gave you the wrong tps, thats what happened with mine, i replaced mine it didnt work, it looked just a little different on the inside where it controles how much throttle you give it. so i went back they wouldnt return it, made me mad so i wet to the junk yard and i got one from there and the junk yard oe worked just fine.
