What all sensors on a 5.3 effect the way it runs? (Narrowed it down)
- Thread starter shady
- Start date
I'm not positive if it is actually in the trucks real reduced power mode or if it drops a bunch of power from running so bad and he's calling it that.
Every time I've personally driven it it runs fine.
We had the reduced power come up and it actually said it on the dash before we changed the throttle body.
But when I asked him if it says it now he said no.
But he keeps saying it's doing the same thing it was then. So im not sure it's really going in reduced power mode.

Ever changed the fuel filter or checked for water in the gas ?...
I understand where the OP is coming from but never been a fan at throwing parts at an engine. You don't have to do the real in-depth diagnostics but at least some basic trouble-shooting can narrow down the issue. Don't get me wrong on this and not trying to say they did something wrong, but for replacing the throttle body there is no specific code that tells you up front to replace that part. There are probably a dozen different possible things that could cause that one code, and probably 20 more different codes that have something to do with the throttle body. One recommendation would be to get the specific codes and start googling them, or search for them on YouTube......pretty common you will find a video dedicating to trouble-shooting that specific code on the same vehicle. Just keep in mind that just because it's on the internet doesn't mean it's true...but often at least point you in the right direction. A couple of really good channels are "South Main Auto" and "Pine Hollow Diagnostics". Both guys get really in-depth and explain everything well.
The code it was throwing when it did reduced power mode had to do with the throttle circuit. The guys on here and 3 or 4 youtube vids all said it could be throttle valve motor, throttle position sensor, or a dirty throttle body.
Replacing the TB covered all of those at one time, for barely more money than just the position sensor by it's self.
And the TB WAS filthy lol.

Well, it's a good way to know what parts you take off are worth keeping, and which go into the trash can. At least you know you have good spares.
Tossing working OEM parts for aftermarket is a dangerous game for sure.
both TPS voltage codes. Since throttle body is new I would give the wiring, esp the plugs a close inspection.

great ?!?!?

I've seen a bunch of the LS swaps done on here and have never heard of that module 
. I found it at o'rileys.. but I've never seen it mentioned.
Maybe it was mentioned when I looked it up the first time and I don't remember... I dunno.
Looks like I'll replace that, the pedal sensor, and then the O2 sensors and see how it goes.

Completely agree with the above comment talking about replacing factory sensors with cheapo' generic parts. I'm not professional mechanic by any means but have diagnosed both my own vehicles and several friends and families vehicles over the years. A lot of them after a "professional" shop attempted to repair them but didn't. Biggest example is O2 sensors.....as soon as an O2 related code pops up the first thing people do is swap in a new sensor. From my experience at least half the time it's not the actual sensor that is causing the issue. Wiring, connectors, or simply the engine running bad and the O2 sensor flagging the condition (i.e bad plugs or wires can cause a miss and it to run rich).
Even replacing sensors with AC delco, or the best equivalent?
I kind of don't get the logic in allowing something to strand you before you fix it.
I get that an O2 sensor won't strand you. Or even some of the others.... But like the crank position sensor, cam sensor, etc... I don't see what it would hurt to replace them with quality parts since the originals are 15 years old with 180+k on them.
I'm not talking about running out to vatozone and buying the cheapest china sh1t out there. Lol. Not the way I do things..
I don't care about putting money in it. Its the truck my 3 month old grand baby gets hauled around in.

Ac Delco will probably be Chinese too. GM might be Chinese.
In 2005 probably Canada, or Mexico.
