Help,weird OBD codes.

[RollaS]

Hey guys so have an 04 Solara SE 4 cylinder and had a CEL. I just went and pulled the codes(its freezing outside!!!).

Here is what I had
P2102 Throttle Actuator Control Motor Circuit Low
P2111 Throttle Actuator Control System - Stuck Open
P2112 Throttle Actuator Control System - Stuck Closed

For some reason the car was driving weird and the accelerator seems unresponsive. The CEL was on, pulled codes and that is what I got.

BTW I do live in Chicago and is pretty cold right now. Do not know if that has anything to do this this. At first I assumed TB was stuck, but I think the 04 Solara is DBW?

Well if you know what is causing this or how to fix, please let me know. It will have to go to the dealer otherwise on Monday again :-/.

Without knowing for sure do the first basic thing just look around the TB and see if there are any loose or disconnected wires.

[NeFaRiOuS_SLE]

^^ Yeah, it's a DBW. Since I don't know anything about repairing DBWs, free bump.

[RollaS]

Frommy research, there might be a TSB. I cannot find it however, if anyone has any info please let me know.

[RollaS]

I found this
EG002-03 M.I.L. ON DTC P2102, P2103, P2111, P2112 OR P2119 (REVISED)
12/20/2004 - 2003 Toyota Camry. Under certain driving conditions when the ambient temperature is below 32F (0C) some 2003 model year Camry vehicles with the 1MZ–FE engine may exhibit a M.I.L. “ON” condition with DTC P2102, P2103, P2111, P2112 or P2119 stored in the ECM memory. To improve cold weather performance and reduce the possibility for M.I.L. “ON,” the Throttle Body Assembly, Throttle Body Gasket and Intake Air Surge Tank have been updated.

But cannot access the doc.

[NeFaRiOuS_SLE]

Good job! You don't need to give them the document, just give them the TSB code and let them handle the rest.

Uh... but that's Gen1.5 TSB. He's got a Gen2. Unless there's a similar one for the '04.

Something's frozen. It was single digits this weekend. So to solve your problem, move to FL.
Funny how it got stuck open and closed. Perhaps it was an intermittant problem that freed up once you warmed her up. But the codes were leaving the CEL on. How's she driving once you're rolling for a while?

Yes I did not post that up, but I noticed the TSB was for the older Gen. Dropped it off at the dealer, let us see what they say. I found out from a toyota tech that he has replaced a lot of DBW systems on these cars .

As usual, when you try to tell a dealer what it is or might be, they do not care. They act like you don't know crap lol, so I just left it at that.

On a side note, the SCed Corolla is pulling harder with the nice cold wind! No stuck throttle haha.

[RollaS]

Oh yea sorry, after letting her warm up for 20 mins, she would drive just fine. So I popped the hood and did not see anything. I was going to open it up and clean the TB, but too cold outside!!!

I wanted to clear the codes after car warmed up to see if it comes back. I did not clear them, since I knew then the dealer would not be able to reproduce or see the codes. Even if I showed them the OBD stream. I wonder if they will just clear it and give it back to me?lol

[RollaS]

Well talked to the dealer. The homo DBW TB is screwed and need a new one, $1200 for everything! WTF?

The TB alone is $900!!! WTF is with this ghey car?

Can anyone tell me where to get a new TB for cheap? I have been looking around with no luck .

[Down2TheC]

I doubt it's truly screwed if it's just a thermal failure (only when extremely cold.) I'd bet that once it's warm you could clean the moving parts and maybe lubricate some joints (not sure about that) and you'll be back in business. The Toyota techs often think in a modular fashion. Don't fix, just replace. For $1200, I'd try a few DIY attempts first or buy something to preheat the TB before you start up for the day.
Any gearheads out there know what parts of the TB might be first to gunk up and stick in cold weather?

As for the DBW thing, that just means that some servo is moving it. The functioning is the same. But I'll bet if you had foot-to-throttle connection it wouldn't be "Stuck". The servo is probably pretty wimpy and if it's not easily moved it labels it "jammed". So don't let them use that as a reason that it's toasted.

Short of any more knowledgeable replies, I'd point you to the TB cleaning thread in the Gen 1 Tuts. Should apply to your car just fine.

Thanks for the tip.

A toyotatech on another forum told me he has replaced many of them due to failure. He says they seem to have problems with the DBW motor on these.

BTW there is a TSB
TSB #02305 -- MIL ON DTC P2103, P2111, AND OR P2112. *SC (NHTSA ID #10015938, MAY 17 2005)

Which covers that.

Thanks for the tip Down2theC. I was going to take it apart and try to clean it up before spending big $$$ on a new/used TB. It just started once it got cold, so I assumed it should be resolved. The service manager said they cleaned it, but no luck. I don't trust other peoples work anways, so will try cleaning with TB and electrical cleaner. See what I can do. I'll update you guys once I figure something out.

The cold does not help either, I find it too hard to work on the car in the cold. Need to go buy a garage heater and get to work.

Perhaps a stupid question, but is the car still under warranty? It's an '04 so the 36 months hasn't run out yet. What about miles? if it's under 36,000 miles I would think this part is under warranty.

Damn, I may need to go buy an extended warranty now.

[Turbosolara]

i was wondering if that should be consider under the "powertrain" warranty.

[RollaS]

OK UPDATE

1) the car had about 42k miles or so. The part is covered under 3years/36k, so I was SOL on that. I tried a lot to get them to do it. No luck.

2) I had problems from the get go, when I bought the car with 16 miles or whatever.

3) I was going to open up the TB and clean it out. Sadly it is all the way in the back and a PITA to get to. So I had to wait till Sat. Worse came to worse, I would buy the part and swap it out. Cheapest new one I found was 630 shipped. No luck finding a 04 TB used.

4) The car was just traded in for a 07 Camy LE with the problem as is. I know the 07s have some quirks as well, but hope nothing that bad.
