my tps is bad on my truck and I cant drive it.I must of called 7 auto parts stores and not one has a throttle position sensor for a 03 5.7 hemi I cant understand why.advance can get me one but it will take 6 days they said I asked if they could fedex it over night they said no whats up with that?anyone know why that parts so hard to find?

 

Pretty sure it's incorporated within your T/B because it's a fly-by-wire design.


What makes you think your TPS is bad anyways?

 

Yes, there is no TPS, regardless of what Advance says. Be glad they'd have to ship it. At least they just saved you $40 or so.

 

Yes, it will generate TPS codes though. Very confusing.

 

that's really odd because a repair shop told me theres a tps I don't understand why they would tell me that? hmmmm so theres no tps at all?what do you guys think this guy at the repair shop means when he saystruck needs a tps then?He told me that's why my truck was staling.

 

fly-by-wire design? not really sure what that is.

 

Take the air cleaner off the throttle body and you will see one connector. You have 2 TPS sensors internal to the throttle body. They may have just read the code and didn't look. It can throw codes for "TPS 1" and TPS 2"

You also have an "APP" sensor (sort of but still has a cable) under the battery tray. On newer ones the pedal position sensor is part of the gas pedal.



1 - BOTTOM OF BATTERY TRAY 2 - ELECTRICAL CONNECTOR 3 - APPS 4 - SWING-DOWN DOOR 5 - CABLE (TO PEDAL) 6 - CABLE RELEASE TAB





1 - THROTTLE BODY 2 - ELECTRICAL CONNECTOR 3 - SILICONE SEAL 4 - MOUNTING BOLTS (4)

 

wow thanks for that well I cant check now I had the truck towed to a repair shop since I couldn't figure it out.sounds to me like they didn't check but then again the guy told me he ordered a tps for my truck from a parts store not sure what he means now cause when you call advance auto they will tell you for 39.99 they can order a tps for this truck.thanks tn tech!you know your stuff I should print this.thanks

 

ok so if the tps sensors are in the tb then I need a whole new tb since you cant remove them im guessing.

 

Well, since you asked for a TPS, they probably found it on a different engine in their catalog, I'm guessing. Yes, you have to replace the T-Body. 4 bolts and a connector...easy peasy. (That's IF it's not a wiring problem, but likely not)
