Throttle Position Sensor

HemiBabe · Jun 8, 2011

Recently my truck has died twice at a low speed or at idle. Spring (Ms.MagnumSLT) was havin the same problem in her truck. She said that she cleaned her throttle body and replaced the TPS and it's fixed. She has an 05 w/ a 4.7 whereas I have an 04 w/ the 5.7 hemi. I stumbled across an old thread when I did a search where OklaHemi was throwin a code and it was a discussion about the Throttle Position Sensor.

Everyone was saying that on the 04 hemi's, you had to replace the entire throttle body because it's all one piece.... Is this correct???

just to replace the TPS i doubt it. Autozone should have it

I looked it up on their site and it came up with results for GM products....

Anyone know something???

I know I had to replace my whole TB when I did mine so I urgraded to a ported one for the same cost as an OEM one. Mine was acting like it was on crack, would shut the truck off, flash the lighting bolt, read out over 150% throttle travel.

HemiBabe · Jun 9, 2011

Right, mine just died out of nowhere and I hate the feelin when you never know when it's gonna die on you. Plus, it's embarassing lol. So I guess I'm pretty much screwed on that part, but it's a good reason to do an upgrade. What mm is good to get and where'd you get yours from? Fastman?

im pretty sure you can just replace the sensor, try autoparts warehouse or a site like that, they shouldnt be more than 30 bucks. But if you want to upgrade the whole throttle body, might as well.

What about this one?

3rd Strike Performance Bored Throttle Body 03-04 5.7L Hemi [3rd Strike Perf Throttle Body] - $269.95 : 3rd Strike Performance!!, Mopar, GM and Ford Performance Parts-Aftermarket Accessories!!

I was wantin to just take mine to get it bored anyways but hell, might as well just get a whole new one if I can't replace just the sensor. Summitracing says that it doesn't exist for my truck.

Here is the thread I found where everyone was sayin you cant replace it for an 04... i wish someone who knows would chime in :banghead:

everything that I am reading says that you have to replace the throttle body. i have the haynes manual and it says the tps is not removable from the throttle body. might as well uprgade

Alright well THANK YOU very very much for lettin me know that. I had no clue! Well, I guess it's time for another mod! Thank you Dylan!

dth418 · Jun 9, 2011

No problem, I wish i had some more information for you. Let us know what tb you go with and put up some pictures!

KGBIGCOUNTRY · Jun 9, 2011

Mine came from Fastman but Duanes price is great on it I would go with his. The specs on it also look good.

HemiBabe · Jun 9, 2011

Alrighty! I compared prices too and Duane does have good deal, plus we get 5% off for bein an RF member... Time to drop some cash tmrw when I get paid... dangit.... lol

KGBIGCOUNTRY · Jun 9, 2011

Look at it as a saftey standpoint, atleast thats what I did. Mine cut off while taking a interstate exit once... I didnt drive the truck after that except 2 miles from my house to hook up to my bro-inlaws scanner to run #s on the TB operation then parked it till my new ported one showed up.

HemiBabe · Jun 9, 2011

Good point... Alright well I'm still kinda excited, my first real engine mod! Yay!

Thanks again for yalls help!

I found a site that says the TB porting adds 8-10 RWHP to the 5.7's ... not bad at all really

dth418 · Jun 9, 2011

8-10rwhp, how much is it?

HemiBabe · Jun 9, 2011

$270 plus shipping, but RF members get 5% off

and that comes ported?

dth418 · Jun 9, 2011

thats not to bad. That shouldnt be to difficult of an install either.

KGBIGCOUNTRY · Jun 9, 2011

Nope not hard to install at all. Pull the intake of whatever kind you got, pull out the 4 bolts and unhook the electrical. Just a heads up the 05 TB is a diff connecter then the 03-04 ones for anyone looking to order later on for their own truck.
