Throttle Position Sensor

No this definitely works on our hemis, really needed to do it after i cleaned my TB. I can verify this works.

Dan, of course you can do what you like but I am taking the information I provided from the service manual.

I don't understand. Are you saying this does or doesn't work? Im confused now.

so did the burnouts contribute in you guys op

Ahh I see you are talking about making the comp mate with the new tb right?

Agree, doubt if burnouts had anything to do with it..

Dan, the procedure you used has been going around the forums for a long time. Unfortunately it is not the right procedure for our 5.7 engines.

Taken from the Diesel section:
ECM Calibration: Turn key to ON position.
Without starting engine, slowly press throttle pedal
to floor and then slowly release. This step must be
done (one time) to ensure accelerator pedal position
sensor calibration has been learned by ECM. If not
done, possible DTC’s may be set.

Interesting seeing as how that procedure worked for me. After I cleaned my tb, my accelorater was acting odd, hangin up, taking a long time for the rpms to die down. That procedure fixed it for me.

My guess is your PCM manage to read the TPS voltage inspite of what you were doing. I've posted what is in the manual, by no means does anyone need to take my word for it. Simply look it up yourself. The diesel throttle procedure has been a Hemi myth for a long time and no doubt will continue to be propagated.

The 5.7 procedure from the manual is:

(6) If the throttle body has been changed, the following
procedure must be performed:
(a) Disconnect negative battery cable from battery.
Leave cable disconnected for approximately 90
seconds.
(b) Reconnect cable to battery.
(c) Turn ignition switch ON, but do not crank
engine.
(d) Leave ignition switch ON for a minimum of
10 seconds. This will allow PCM to learn throttle
body electrical parameters.

he said propagated, im going to take his word

Sorry for the bad info, I found it on another site so I thought I would share. Oooops

Guys, the diesel procedure got posted and many hemi owners believe it to be the correct procedure. It became a hemi myth. I am not asking anyone to take my word for it. Just look it up in the manual. But that is part of the problem it is not easy to find and in fact you don't do anything but turn the key on after rebooting the PCM. Which is less satisfying then actually doing something like pushing on a pedal and counting to 10. Keep in mind anytime you see ECM you are talking diesel. And if you search "calibration" it takes you to the diesel procedure. For the Hemi procedure go to in the 03 manual (14-48) Fuel Injection - Gas section, 5.7L V-8.
5.7L V-8
CAUTION: Do not use spray (carb) cleaners on any
part of the throttle body. Do not apply silicone lubricants
to any part of the throttle body.
(1) Clean and check condition of throttle body-tointake
manifold o-ring.
(2) Clean mating surfaces of throttle body and
intake manifold.
(3) Install throttle body to intake manifold by positioning
throttle body to manifold alignment pins.
(4) Install 4 mounting bolts. Refer to Torque Specifications.
(5) Install electrical connector.
(6) Install air plenum.
(7) If the throttle body has been changed, the
following procedure must be performed:
(a) Disconnect negative battery cable from battery.
Leave cable disconnected for approximately 90
seconds.
(b) Reconnect cable to battery.
(c) Turn ignition switch ON, but do not crank
engine.
(d) Leave ignition switch ON for a minimum of
10 seconds. This will allow PCM to learn throttle
body electrical parameters.

Good luck guys, lets see if at least on this forum we can put this "Myth" to bed.

It's not from the burnouts.

I see now red-truck, what must have happened is the 10 seconds went by when I was pressing the pedal. Here are the images from the manual. Thanks for putting us straight.

It is only a sign I have too much time on my hands.... Hell, all I do is drink beer and ride my motorcycle around. Not that I am complaining. Plenty of beautiful things to see in the land of smiles....

You and me both buddy

i guess the problem fixed itself. i went out and started it, fired right up. nervously put it in reverse, no problems there. threw it in drive and crept down the street, everything was fine. increased throttle got to around 40 where it was acting funny before, it upshifted just fine. i sped up and took it to 60, still no problems. i took it back home and went ahead and did the reset as posted by greg. weird that it happened and fixed itself. oh well thanks for the input guys. im glad i dont have to buy a throttle body quiet yet

Should still pick up a ported one.... it will make things a lot more fun

It's good it is running right, but I'm always nervious when things get magically repaired.
