Well i am having a problem with my truck, Recently its been shutting of and the dash shows "check Gauges". Most of the time it happens when i am slowing down for a stop or a turn. Does anybody have a clue on why does it turn off.

 

change the fuel filter, that would be my first guess

 

tps sensor. fuel filter or gas pump. get it diag.

 

It sounds like a dirty throttle plate. These engines don't have an idle air controller so if enough carbon builds up on the throttle it interrupts the airflow and will cause the engine to stall anytime the engine is brought down to or near base idle.

 

I think it could be the TPS. You might need a new throttle body... the TPS might have broke.

 

Maybe, but why begin troubleshooting with the most expensive fix.

 

I recently had a similar problem of my truck shutting off. It turns out my battery cable was corroding and the connection was perpetually getting worse. So I cleaned the cable and battery of any corrosion, hooked it up and coated the connections with vaseline.

I hope for your sake it's that easy of a fix.

 

Well i already got the fuel filter changed two days ago, so i know that is not the problem. I know the battery is not corroding, and its making full contact. Only the engine shuts off, all the electronics still stay on, it turned off on me twice today. I am going to go check the TPS later today to see if that is the problem. Thx again

 

Well, they'd follow up on your response about cleaning it, and then follow mine about the TPS being busted.

But if everything looked all gunhoe in the throttle body (very clean), then I'd be leaning towards the TPS sensor.

 

Well I ended up taking the truck the the dealer to get it diag, They ended Calling this morning telling me that i need a new throttle body, and that it needed reprograming. They told me it would cost me $588 for all of it. Any idea why i would need a new throttle body , i checked It the day before and it was clean, it dint look dirty or anything.

 

Wow... I'm good. I should work for Ford.

They just go bad.

Then again, I had a mechanical throttle body spring break on me, and I got taken for a nice WOT ride and a nice ticket.

 

could i just get another throttle body from another truck and swap it out, does it actually need reprogramming. OR could it just be the sensor? can i just swap that to? Because i was reading that the sensor was not reusable. Is the Tps the same on 4.2L and 5.4L, does the throttle body come with the sensor if i buy it from the dealer.

 

No. There is quite a difference... not only in how it works but also the prce tag.

 

Good job Manual!

 

Manual do mean the tp sensor, what about the other stuff? Do they actually have to program them? Because i want to order them online.
