If you don't have a tuner you can clear it by turning the key to 'on' for several seconds (without starting) 4 times in succession.
Remember that, because my BBK left me stranded in limp home mode 60 miles from the house and the tow was $300. Be very careful when driving at throttle openings greater the 60% but less than WOT. There is a comparison chart in the PCM that looks at MAF vs throttle angle, and mine was always confused at the above mentioned run conditions. I never did get it solved and returned the TB. Good luck!

Personally, I believe these pieces need an upgraded tune installed to run properly, no matter what the manufacturer says...

When I did my BBK the error code stayed on too. What you can do is a soft reset on the car. It will reset your clock and radio settings...
All you do is disconnect the neutral part of the battery, and let it sit for like 5-10 min. Then reconnect it, the error code should be gone. (hopefully).
That's how mine was able to be fixed. Like you when I installed it, matched the voltage and it still read an error code... and not having a tuner the battery disconnect is what fixed it, since I knew nothing was wrong.
Hope it clears!

I dropped a BBK 1763 Twin 62mm Throttle body on barry but I had voltage matching issues...
after putting it off and on 4 more times I got it going.
Stock TPS voltage was 1.286.
I would set the BBK to 1.286 then take it apart to tighten it down.
Then I would put it back together and install & Double check it but
it was at 1.292...... huh??
Took it all apart and started over. :roll:
Happened two more times so I backed it down to 1.281 then
put it back together and installed and it was then 1.286.
Somehow in tighting it all down it would increase .006
Soooo now its set. Fired it up and it works LIKE A CHAMP!!
Noticeable throttle response!
instructions call for a battery reboot so your PCM learns itc changes.
The 4 cycle key resets it but I pulled the negative terminal just to be sure.

Why they make this so confusing is beyond me. There is no way
I could have done it based upon the instructions.
The TPS is there on the left (pass side) and the bolt you adjust for the volts is on the right
(drivers side).
See this screw?
Thats what you twist to adjust the volts. You cant adjust it cause its locked in place with
a set screw in the side of the TB under that black plastic housing on the drivers side.
Turn your key in your ignition till its one click from being on.
On the pass side you will see a yellow wire on the connection.
It should be the bottom wire. Put your volt meter in there while its hooked up.
Dont unhook anything. Just ground it and stick the red probe in there.
Write down the reading.
That is what your BBK needs to be set to.
now take off your stock TB and put on the BBK after swapping
the sides out to the new TB (be sure and set the spring correctly).
Turn the key to get juice there and check it.
If there is a difference you will need to remove the drivers side assembly.
That bolt in the picture above is held in with a set screw (alan wrench)
that is located underneath the black plastic assembly...hence its removal now.
Loosen the set screw...no need to remove it. Now feel how you can move the
bolt with your fingers?
Well...you will need to reassemble it. Be sure spring is set in correct. Leave the round window off
so you can turn the spring counter clockwise around 180 degrees and set it in the slots.
Needle nose plieers work perfect for that. You have to do that so that there is tension on the other side of
the adjustuing bolt.
Now turn the iginition on (dont crank the engine) and whip out the meter again.
Check it. Now twist that bolt and you will see the voltage change.
Keep playing with it till you get the exact same reading that you wrote down earlier.
Then stop. take off the drivers side again and now tighten the set screw (alan wrench) that
holds that bolt in place. Being very careful not to move it cause that will readjust your voltage again.
Reinstall....twist spring again....turn key then double check with a meter.
In my case I was off by .006 so I took it all apart and did it again. Same thing happened
so I adjusted the other way by .006 and reinstalled and it backed up to perfect. I dont
know what was going on or even if being off by .006 volts mattered but in tightening it
all up it moved it just that much.
So once it was reassembled and set the exact same as the stock TB I then pulled the red
battery cable. Let it sit for a good 15 min. Take that time to clean you battery connections!
then hook it back up and fire it up. The first fire took a couple seconds cause the ECM has to relearn
the flow. It was magic after that.
the only thing you need to do to the pass side connection is check the volt readings.
last thing to do is snap that spring housing round plastic window back on.
Clear as mud right?? lol

Thanks for the great info "Barricade", I had no idea how that was done. i am waiting on delivery on a GT 500 TB (60mm) which is supposed to be plug & play. But NOW I am going to at least check the voltage before and after the install.
I am going in for a Dyno tune the following week any way, but this is very "enlightening" some one should do a picture how to for this. Like many things it doesn't seem difficult once you know a few of the secrets...LOL
Thaks again

It may not make a difference....Im not sure where the tollerances lie
and I could make it exact, sooooo I figured why not make it exact...?
Just make sure you set that spring each time before you check the volts or it will
throw your meter off OR it will read the exact same. It like freezes the setting....
if that makes sense.
Anyways.....it was quite a headache to figure out but after feeling the results (about 25hp that feels like 50)
from my buttdyno -I am very pleased.

sorry for the delay in thanking all that replyed was in Dakota. Error actually cleared after 30 miles of driving after restart. I am running a tps voltage at around 1.288 and it seems to respond better without to much in rpm lag in dropping between gears.thanks to all
