Throttle Lag TSB is out

[Lone Solara]

It did improve some, but not as much as I would have liked (this was on my 2004, which I've sold shortly after). If I had had the time, I would have asked them to do it again. But there was a definite improvement.

I'm not sure why they're not more careful. The TSB expressely states that if they don't follow the procedure, they run the risk of frying the ECU. Oh well, I guess $1500 is not a whole lot of money to them.

Okay - I did a search on this topic and see that not much has been posted on it for a couple of months, so I thought I'd ask...

Does anyone know if there remains a problem that a TSB will resolve Re: the lag when accelerating on an '06 V6?

It's horrible I must say! My girlfriend's '02 V6 Camry XLE doesn't hesitate at all but my brand new '06 V6 SLE is kinda nasty when you punch it. Reminds me of an old Holly 4-barrel that's flooding!

Thanks for any help anyone can give!

I'm not sure what the deal is... the problem was supposedly resolved with the later '05s and all '06s, however we've had several people with '06s mention that they 'think' they have the lag...

I got the lag fix for my '04 last year and there was a SUBSTANTIAL improvement (it was like driving a different car off the lot)... however I have a kinda weird driving style, and I can still get the car to lag on occasion... It's a fault of the drive-by-wire throttle system... and I don't think that it can truly be 100% corrected.

Drive by wire has been an issue with all the Toyotas over the years - and as I recall, was always an issue in the Tundra forums as well. But I gotta tell ya that even with my '01 Tundra 3.4 V6 I never experienced the kind of lag I get with my new Solara.

Sounds like I need to get it in to the dealer to have them check it out.

For anyone who needs to print out a clean, full-color PDF of this TSB (TC006-05) - then I've put it up on my server for you to download here:

It looks like by description of hte complaint, that it is supposed to take care of all that has been buggering me the past couple of weeks!

Might be helpful to point out the fuse removal on page 5 to the service writer so they don't accidentally fry your ECU too!

Good luck!

I think a problem in addition to the drive-by-wire is how the car attempts to maximize efficiency. It seems whenever the car detects me being a little easier on the throttle, it significantly reduces the response. I've had the TSB done and right now it lags as bad as it did before the TSB. If I get more aggressive on the throttle the car seems to relearn that I want fairly aggressive shifting. Irritating as hell and all in an attempt to boost the mileage. IMO, the TSB is not a final fix.


Also, there have been and still are similar complaints with just about every brand of vehicle utilizing drive-by-wire technology. BMWs do not seem to have a problem, at least not to the same degree, but Audis, Acuras, etc., have had or still have similar problems with lagging. It isn't just Toyota.

does anyone know if there is a TSB taht applied to the 4 cyl..... cuz i noticed all of u guys have v6
cuz i feel similar lag to u guys but it could be my engine....

I had the car at the dealer for warranty work and I had them reflash the PCM. They called me back and told me I have to run premium gas, which I already do, once the the car is reflashed with the update program. Not sure why that would matter?????

[slingshot]

Same exact thing happened to me. I eased up on accelerating to get better gas mileage and started getting lag again. THen I accelerated faster more often and lag went down. Maddening. It seems you always have to drive pretty hard to get rid of lag. I had no idea Acuras and Audis have the same issue.

Okay - talked with a service writer at Carson Toyota today about the lag - explained the problem I was having (being sure to word it just like the description of complaints on the TSB) and said I did a little research on it and people have been having this problem for a couple years now...

He said there is a TSB for the V6 Solaras and to bring it in and he'll make sure I get it taken care of.

So - I've got an early am apt and I'll report back with my results tomorrow!

After the ECM was reflashed, no more lagging. This should not be a TSB but, a recall. This problem is dangerous and should be addressed by Toyota.

[kingkakyle]

lol recall would be awful
we wouldn't have our cars for awhile =(

[Blacker]

God forbid a recall. It only takes 1.5 hours and only affects two model years of Camry/Sienna. When I pull out of my housing development, having a 2 second delay in throttle response can make for a bad day if I got t-boned. Ahhhh, the days of a cable between my foot and the throttle body.
