Been looking at this TPS all day and trying to find info out there on how to adjust it. I found some info about adjusting the voltage between a green and red wire or - and return sig.
Sounds easy BUT mine has 4 wires -a pink, a grey, and 2 yellow/ white trace.
I took the voltage between the pink and grey and got 4.1 volts. I assumed this was the ref. I then read from grey to each yellow. one yello had 0 and the other had .1
Am I looking at the TPS? Its the only one right on the throttle body with security screws -right?
The 5.4l 3v Doesn't Have A Tps Like The Older Stuff. The Tps Is Also The Iac, And The Throttle Control. Adjusting The Voltage Might Not Be A Good Thing.
every time I bring it there it comes home with PROBLEMS. Seriously I brought the thing there to have the bedliner sprayed and the DVD system didn't work when I picked it up. Thats not the only thing... the f*d up a bunch of stuff on my new baby lawsuit pending...
The idle stumble/stalling is a common problem with the 5.4L's. Mine did the same thing. I know you hate your dealer, but try to find another one, because it does need repair. They will probably reflash the PCM, and possibly replace the throttle body with a new one. They did this to my 2004 5.4L because I had the same problem...and it 100% solved it. Hope this helps.
Dang -thatmeans I have to have these clowns climbing all over my truck...
Dropping crud into my intake....
I can flash my own PCM right? If I throw on a super charger it voids all that intake crap right?
No, you cannot flash your own PCM unless you "know" someone at a Ford dealer willing to do it for you on the side. The software update must be downloaded from Ford, and only they can flash it.
And yes, adding a blower can void your warranty UNLESS (this is my understanding)....you buy the Ford blower...AND have it installed by a Ford dealer....then I THINK you can retain your 3/36k warranty. Might wanna check on that tho. If anyone knows, please chime in.
I just had a new computer installed in my Jeep, and the garage mech flashed it. He's not a dealer, just a garage. I think those little boxes to do it are over a grand.
