Throttle sticking at 3k Update "Long" - Page 14 - SRT Forums

gnat turner · 05-17-2004, 07:40 PM

I know I said I was going to scan the invoice this weekend but problem resurfaced. I'm not sure what the problem is. It doesn't seem to be the TPS wire harness (nothing happens when I wiggle it).

This just started in my car last week, ugly with my commute. When it freaks out at idle I get some nasty noises . . . I'll be going into service tomorrow.

My car did this when the line from the PCV popped off of my catch can at the track, hasn't done it since hose clamps were installed. Maybe there's a leak in that line somewhere?

Funny, after reading this thread and posting, the next morning it went out and played with all the wires around the throttle body. Of course this was at 5am so it was in the dark, so I just pushed all the connectors in, etc. - happily enough this fixed my problem.

So it's obivious that I've got some sort of harness issue that is going to be a real pita to get fixed . . .

Even more frustruating is that this is the first problem I've had with any of my four new American cars in the last 8 years (2 Dodges for me and 2 Saturns for the Ex). If I end up taking it in for service I won't be able to make fun of my import driving friends (as much) anymore . . .

and i was right, they had to order a harness......replaced the tps and it threw the code again.......and is still acting up....silly dodge dealerships

well i finally got the 0123 code. my car has been acting up for about 6 months. i put my stage two in and it gave me that code. is there anyway to get just the harness and the sensor and do it myself or have a mechanic over here in england do it? how much would it cost? there aren't any dodge dealerships here so i don't know where to go. how hard would it be to change out the harness? i imagine it to be pretty hard.
thanks

Finally took my car to the dealer, they called me back within the hour saying they had to order the new connecter and that it would take the better part of a day to install it (which I take to mean they are replacing the wiring harness).

My car is displaying all the symptoms described by y'all here and is becoming an issue to drive with my long commute, as well as guzzling gas at an alarming rate. I'm used to getting and need to get my 30mpg because of my commute - this is doing a number on my budget.

Anyway - Dodge needs to address this soon, it's not dangerous but extremely annoying.

My car is acting similar when I an coasting to a stop or just coasting in neutral down the road the rpm rise to 3k stay there or they drop to about 2k and rise again. I took it into the dealership and they replaced the tps after calling star. There is a TSB for the number 4 spark plug wire and spark plug. They replaced those and it still didn't seem to help. I'm going to bring it back in tommrow and see if they can figure it out. I will try and see if I can get ahold of any TSB's for the srt-4 from the dealership.

Not the sensor. Have them jiggle the TPS white striped wire connecting to that sensor under idle. It may be a short in the wire loom and needs to be replaced.

Now, hemi, how come replacing my sensor 20,000 miles ago fixed it? With no reoccurance?

hemidakota · 06-15-2004, 07:58 AM

Actual, there are two codes you get from this little problem: 1) P0121 or 2) P0123. I had both. Remember. I drove it like I stole it fromthe showroom floor and a few little devices thereafter.

My TPS went out twice and the wiring once. The wiring loom was twisted around from the factory. Someone was not paying attention when they did the first few cars. LOL

glhs837 · 06-15-2004, 08:05 AM

Ah, but I never did have any codes at all. Some folks don't get one.

craigswardmtb · 06-15-2004, 11:26 AM

I replaced my TPS myself and that didn't fix the problem. So i brought it to the dealership and they said the car was running fine and there was no problem. I showed up and sure as shit the car was running perfect, minus an obnoxious whistling sound that the turbo now makes which it never use to. But i think that may just be a boost leak. I'll resolve that later.

The funny thing is the car ran constantly like crap for 4 days, constant revving, all the way up to the point when i dropped the car off at the dealer. Then according to the dealer it magically fixed itself. the wire wiggle test didn't do anything. I think they may have done something but i can't figure out what. But why would they not tell me. Either way its been over a week since I had it at the dealership and it is still running and idling perfect.

Before i took it to the dealer i removed my catch can and motor mounts, not that it really mattered because i already have soo many other mods. But i did notice that my catch can line was pretty collapsed and not breathing properly. NOt sure if that could have caused my problem and if it did, the problem should have fixed itself on the drive to the dealership...

I ahve a funny feeling it will resurface.

Hemi, I have an 04 and the TPS sensor has 3 wires. 2 orange (one has a stripe) and one black. The IAC has two wires, both purple (one may have a stripe). maybe the 03's have a different colored wire.

glhs837 · 06-15-2004, 11:36 AM

Don't get me wrong, I'm not saying it's never the harness, just that it's not ALWAYS the harness

hemidakota · 06-15-2004, 11:39 AM

Yes, it seemed they replaced the wire loom.

The voltage line was a white striped wire. Star Tech Center told them to add more length to the voltage line (splicing in a small two-inch wire).

When I drove up, the mechanic used a MOPAR version of a diagnostic plugger. He check the voltage output of the sensor and found that the voltage was not in factory tollerance. If my memory serves me, it should be 5-volt range. This was done after replacing the TPS sensor to correct one of the sticky throttle problems. The wire loom issue was to correct the radical idling problem (fluctution of idling range from 300 to 1100 RPM).

Resurfacing has happened (radical idling) and found that the TB vacuum hoses came apart enough for some form of leakage. Reconnected them and no problem again. Like Starkie, I come to learn to either tie wrap or use clamps for every hoses.

The catch can hose collapsed is usually the wrong material hoses being used. WHen I received Cali's new Greddy Catch can, I didn't used the clear hoses. I noticed the same thing after one hard day of pegging the pedal (love the 20-PSI spike and the 2nd-gear tire burns), I removed the clear water hoses for the fuel type material hoses.
