well i went to the dealership and bought a new tps for 100 bucks. kinda pricy compare to some other thread i read posting a website that sold it for 43.00 shipped. its working fine now, even the check engine light turned off. i hope its not a temporary thing.

Try this, it's from BBK. Mine works fine.

BBK 1763 2005+ Mustang GT Throttle Body Troubleshooting Guide[/b]

If you are having issues with your BBK 1763 '05+ throttle body causing a FAILSAFE[/b] mode or CHECK ENGINE[/b] light, try the following procedure-

First be sure that the plastic capped spring is hooked into the gear and rotated approx 180° COUNTER-CLOCKWISE until it pops into locked position.[/i][/b]

If that is verified and correct and you are still having issues then follow the directions for checking TPS voltage.


CHECKING TPS VOLTAGE[/i][/b]
To check the TPS voltage you must have a DIGITAL[/b] voltmeter.

1. Re-assemble and install the stock throttle body.

2. LEAVE THE THROTTLE BODY MOTOR UNPLUGGED[/b] (the small connector on the driver side of the throttle body).

3. Ground the black wire of your meter and poke the probe of the red wire on the meter into the YELLOW[/b] wire of the TPS sensor which is the bottom wire on the plug located on the passenger side of the throttle body. You DO NOT[/b] need to break the wire to read voltage. The best way to probe the yellow wire is to poke the probe into the plastic harness plug (while it’s plugged in to the TPS). You will need to penetrate the blue insulator the goes around the end of the yellow wire (hidden inside the harness plug) to reach the bare metal end of the yellow wire. Touch the probe to the bare metal end of the yellow wire

4. Turn the ignition to the ON [/b]position but do not start the car.

5. Read the meter display. You should see a voltage reading between 1.19-1.31 volts. Write the voltage down.

6. Now re-install the BBK throttle body and repeat steps 2-5.

7. If the TPS voltage on the BBK throttle body varies from the stock TPS voltage then follow the next steps to adjust the BBK to stock settings. This is easily done with the throttle body bolted to the car.

ADJUSTING TPS VOLTAGE[/i][/b]
1. Remove the motor housing from the throttle body and loosen the tiny Allen headed set screw that locks the brass plunger into place.

2. Hook the plastic capped spring back into the gear and mount the motor housing cover onto the throttle body with a few of the screws to hold it in place.

3. Rotate the plastic capped spring approx 180° COUNTER-CLOCKWISE until it pops into locked position.

4. Using a pair of pliers or Vise Grips while watching the meter, turn the brass plunger clockwise to increase voltage or counter clockwise to decrease voltage until the meter displays the same voltage reading you noted from the stock throttle body.

5. Once the correct voltage is achieved and verified, you may remove the motor housing cover and tighten the set screw back into place then re-assemble the BBK throttle body for driving operation.

6. Plug the throttle body motor in.

7. Turn the ignition key to the ON position, then to the OFF position 4 times to allow the car to check the throttle body for proper operation.
If the throttle body is correct then the CHECK ENGINE and FAILSAFE warnings should be gone when you turn the key on for the 4th time




If the throttle body is sticky or rough feeling in it’s opening and closing action with the motor off of the throttle body-[/i][/b]
[/i][/b]
Remove the T.B. from the car.

Remove the motor housing and spring.

Swing the blades closed with your finger hard enough so the gear bounces off the plunger and back open a few times to make sure they are free moving. They should at least bounce all the way open and back closed and open again 1-1/2 times or more. If it stops abruptly then follow the instructions on centering the blades in the bores.

Slightly loosen the screws that hold the butterflies in place (just enough for them to slip around, but no more than that).

Hold the gear so it pushesthe plunger all the way down and forces the blades closed in the bore.

Use the handle of a screwdriver and lightly tap the blades as if you were trying to force them closed even further (thisbasically centers them in the bores).

Now swing the blades once again to see if the action is now smooth.

Tighten the screws back up but don't over tighten them.

Reassemble the throttle body and install on the car, be sure to check the voltage again with your meter according to the TPS setting instructions

It just never ends with the TB's. I would think by now they would have come out with a better product.

ebr

I just took mine off on installed a v-10 tb same elec. works great .

ModernMuscle

do you have no hanging of the throttle, or anything at all?
if not, maybe your car was a lucky one of the 1% that dont have problems.

howarmat

the V10 or gt500 TB all work perfectly with no issues at all.....

ModernMuscle

I was referring to the post that said his bbk worked fine.

howarmat

I wasnt really replying to you about it, i was just stating that these are TB alternatives that seem to work flawlessly as he mentioned before.

The 1st time I went to the strip, on my 2nd run the car went to limp mode and gave a code that the TB was stuck open. Shut car off and restarted and got down the strip out of the way. On the 3rd run it went to limp mode after the end of the 1/4 give codes of stuck open and stuck closed. I worked the blades a few times and set the tune more rich (using crap canned tune) and it worked fine. I've since played with different canned tunes and it's doing good, no more trouble codes. I'm wanting a dyno tune but also want to get all the parts I want to add first. My best 1/8 in Mobile was an 8.36 and my best 1/4 so far was 13.361, all on stock tires and a poor driver (me.) If I really am in that 1%, maybe I need to hit a casino on the way home.
