Mustang 5.0 Throttle Position Sensor Adjustment TPS 

stock setting for the TPS is supposed to be under 1 volt. the actual setting it was at before you messed with it is a perfect setting this info was direct from Ford

Thank you so much. After weeks of working on my 87 5.0 I couldn't figure out the rough idle after replacing just about everything from plugs to all new vac hoses. I was about to give up and found your video. It fixed it so far, I'm going to buy a new TPS today just to make sure, but ill enlarge the holes again if it does the same. Thanks again.

Got a 91 Merc GM that was running like crap, engine light on and off, etc. Followed your video method here and the car runs fine now. Had .888 volts to start. Check engine light flashes were 63-low voltage at TP sensor. I set it at 1.08 volts. I'll take it for a drive later, see how it goes. Thanks man for the video.

Anything between 0.75 and 0.98 is good, under 1 volt!!! NOT over!!! Yours is too high!!=)

Like stated, don't touch your TPS sensor. This isn't 1995 anymore, and the reverse engineering of the EEC has shown that as long as its above .49 and below 1.1, once started the EEC resets this value relative to zero. Below or above those values sends a fault code. Simple.

Thanks for the easy to use guide. I replaced my IAC and never ran right afterwards.

My 1990 Notch would not even fire with a bad TPS sensor....would start for a split second then shuts off. Installed new one and fired right up runs like a champ. Crazy it went bad in storage

Best TPS settings video on the internet.👍

Anything close but below, 1.0 will be Great. .99 will give you instanous throttle response. Anything close will be Fine. Thank, Keep on Dreaming

the information i have on the tps is 0.98 or 0.99 V with the engine not running or 1.03 1.05 with engine running

I have a 93lx with a 306. I am having a frustraiting problem and will try to explain it as follows: I have sluggish acceleration off the line and the car sometimes stalls. Would a new tps sensor fix this irritating problem? Also, how hard is the install? and what would a dvom(digital volt ohm meter cost? Many thanks for your time

Thats the same exact TPS in my Buell XB12Ss, Harley Davidson wants $325 and they pretend they are running out. Motorcraft CX1133 is only like $35 bucks. Same with their 135 tooth 1 1/8" belt drives they put on all their 850lb baggers. They want $300, but its just a Continental CTAM Timing Belt HB135-118 Reference OE/OEM Number: HARLEY-DAVIDSON MC 4030700 G05001AKF, same kevlar belt. Never go to the stealerships for parts

i can tell u everyone this works especially if u have i mildly modified mustang or 87 Lincoln mark 7 LSC

I have a 94 5.o and I went threw everything replaced fuel pump filter and all new sensors when you go to take off she's fine but getting down the road it just don't wanna run any tips would help...

Dude just stop please...go over to Brew2L and watch his video on doing a base idle reset. You're killing this car!

Es posible que subas el video en español para beneficio de muchas personas que tenemos mustang.gracias

i gained 12 rear wheel horsepower 🐎

Mine I change the intake manifold to a slightly higher and now I have no throttle response not sure why. Maybe it's the throttle sensor or something else.

Interesting tuning tip!! I was thinking you might want to index the sensor in case you need to remove it for some reason, that way you can put it right back into position without having to re-tune.

Good vid,ima having a lil rough idle at start on my 94gt,just got a volt meter for 4 bux and im gonna try this out,im running a lil rich

Interesting fix, is the maf sensor clean and within specs, this would account how the tps affected the performance so much.

Ok, maybe I am wrong. I just know on my T TYPE i did the same thing after reading on the internet it was a good thing. It wasn't, i had to get a new TPS and after I set it within spec the car ran perfect. It ran fine before, no CEL, but it definitely ran better within spec. If it works for you great, i will shut up now

set your timing to the 14°mark as well

My 92 Idles fine has no problem revving from 1000 rpm on up, but it almost feels like it has to fight to rev right as I press the gas pedal from a lower idle. Is that the symptom you were referring to when you said "all of the hesitation is gone"?

I have an '01 Grand marquis 4.6L but using '02 Mustang GT throttle body, so what should the voltage on the TPS be, the same?

I have a 1993 mustang with a 306. what should i look for if/when i adjust it for volts? I am running 36-40psi for fuel. Many thanks.

Would this cause my GT 40 5.O shift too soon at 4000 rpms at WOT with an AOD transmission?

Oldsmob455, What voltage would you recommend for a 1995 SVT Cobra? At the moment I have a problem with the idle. My RPM needle bounces around way too much. And the engine even boggs out at times. (turns off while in use) Here is a list of a few mods done to my Cobra: V1 Vortex SC, shorty headers, Ford Lightning mass air intake, 39lb fuel injectors. The 302 engine is completely rebuilt for performance as well. Given the short summary of mods on my Cobra could you recommend a good reference for the TPS?

Thanks this helped so much.

I have 1995 gt few bolt ons idle is very poor set timing n firing order but it didn't help ,will tps adjustment work or make a difference as same on fox body 5.0

Hey! Thanks for posting this. I think I have a similar issue on my '91 LX 5.0, it doesn't pull very much at all from a dead standstill, but after about 3k rpm is when it starts to get up and move. It also revs relatively slow in neutral or park. I went to go diagnose this, however I can't get a volt reading from the TPS. I did what you did and pierced the green wire with a metal pin and then hooked the volt meter to it, but it just stays at 0. Any ideas of where else I could try piercing it, or where else to hook it up to?

Thanks

great vid thanks

De que color es el cable que conectate la pinza positiva gracias

you had it at .8+ just by turning it......

.98 is exactly where it needs to be lol

"oh it's spring loaded " 👀no shit Sherlock of course it's spring loaded how else is the computer gonna know the position of the throttle plate so it can disperse the right amount of fuel thus the problem lies somewhere else

NEVER enlarge the slots! It'll cause the engine to surge or something. That can be dangerous!

it looks like you live by me with your vid by the fair park. my car has not started in days. not sure why? could you help out? i'm the owner of swords & dreams on greenfield ave. my name is tom.

I guess you know more than the team of engineers from ford. I guess through shit luck you got the position right. But its irresponsible to say this works, now someone else might do it and its DEFINITELY not the right way. Maybe I sounded like a dick when I said it, I didn't mean it that way, I just don't want people fucking their cars up.

SEE BELOW... Quote " Jerrythenerdful 5 years ago This is complete rubbish. You can look at the Ford EEC strategy and see the computer doesn't care if the voltage is anywhere from just below .6 volts to 1.2 volts. The Ford firmware accepts any key-start voltage in that range as closed throttle.Doesn't matter what it is. 2.71 volts above that is considered WOT voltage, and anything between the key start and + 2.71 over that is part throttle. Ford intentionally did this so people in the field would not need to adjust the sensor. It's right in the code for the computer. That's why Ford doesn't have an adjustment. People have to file and drill to change the setting because it was never necessary to change it. Anyone who has tuned a Ford EEC or read the documents for the EEC knows this."

You are not adjusting a carb on 69 camaro. Its computer controlled, which run great when all the sensors are adjusted within spec. You just cannot adjust sensors and go by feel. You have to find what the correct factory settings are, adjust it to that and leave it the fuck alone.
