I don't have a scangauge. The damn CEL came on again! Is there anyway to run this w/o getting a CEL? You can really feel the difference in hp. My car has alot of kick now.

I used a Generic Scan Tool and the code was P0505 or something like that
But the code was: Idle Malfunction.

On another note

I had the TB installed for more than a month and I do have a CEL, but something weird happened..... On two separate occasions I've started the car (first start of the day) and the CEL was gone. It idle was normal, as if I had the stock TB (it didn't went over 2500rpm). But this lasted only one day (that days). The next day the CEL was back on. But it was nice not seeing the annoying light for at least 24 hours

But it was weird sh*t .....

I am 99% sure that the dealer can recalibrate the ECU to compensate for the new TB. I will be making a visit soon, so I'll try to find that out.

FunctionSpec · 02-12-2009, 08:23 PM

I have had the 1ZZ TB on for about 20K miles. No CEL and no Oscillation. Didn't even use a gasket maker. Usually plastic on metal fills in the gaps but you can add a gasket maker for extra insurance.

I have the Simota CAI which might make a difference. Yaris is bit sensitive to the types of intakes it uses and will throw a code. What types of codes are you guys getting?

*tk-421* · 02-12-2009, 08:45 PM

I also have a Simota SRI with no CELs. Hopefully that won't change when I do the swap.

BIG +1 on that. I'd love to know if a dealer could fix the CEL permanently.

I just got a call from the dealer... They're having trouble fitting the OEM hose to the larger-diameter TB. Apparently they've tried putting the hose in some warm water, which makes it more flexible, but they still weren't able to fit it.

How did you guys manage to get it installed?

yarstar · 03-04-2009, 01:15 PM

I have a AEM CAI which I had to stretch some to get to fit, but it did fit. I looked at the OEM sitting in my garage before I tried to install the new TB, and saw it might be a significant problem to make work. Maybe getting a slightly larger diameter piece of rubber hosing (the AEM looks like radiator hose) and use that.

Please keep us updated on this TK. I am very interested in whether the dealer can re-calibrate the ECU to keep the CEL from coming on.

Thanks for today's update too.

How did you manage to stretch it? I really don't want to start looking for a replacement hose, especially since it may end up being too large for my existing intake.

yarstar · 03-04-2009, 01:59 PM

The AEM hose is more pliant than the OEM hose. I heated it in hot water and then worked it on the TB first, then installed the CAI. It was so tight I didn't use a hose clamp. I think you may have to go with the aftermarket, or another OEM hose (Corolla, maybe?).

I just measured the inside diameter of my 1ZZE TB = 60mm. The inside diameter of the OEM hose is 54mm. That's not gonna stretch that far. The hose has to stretch to the outside diameter of the TB, which is approximately 64mm. The rubber is alot thicker on the OEM hose than on the AEM CAI hose. I'd be very impressed if the dealer gets it on. I bet they'll have to use something else. Sorry your having problems.

Thanks! I guess I'll have to do that then... I just don't want any fitting issues at the other side of the hose. Hopefully the bracket can get it tight enough to prevent leaks.

BTW, I've asked the rep to check about the ECU compensation thingie. I'll let you know what he tells me for sure.

AlexNet0 · 03-04-2009, 03:34 PM

I had to use an adapter like the one here, and only for an aftermarket aluminum plumbed intake, I cant imagine how you would fit the stock air tube on there.

PS, please do let us know if they fix the ECU compensation

PHXDEMON · 03-04-2009, 05:26 PM

in for an update of if dealer can recalibrate ECU.

*tk-421* · 03-04-2009, 05:42 PM

Unfortunately I had to back off on the installation. I didn't know that I needed to find an adapter for the hose, and they haven't been able to fit it.

Now I need to pay double: Once for the swap to the 1ZZ TB, and twice because they need to get the OEM one back in there.

I need to go pick up my car in a few minutes. I'll ask them about the ECU recalibration and let you guys know.

AlexNet0 · 03-05-2009, 06:44 PM

^just FYI it only took me 20 minutes both to put this in, and 20 to take it off... so I hope they aren't charging you out the a$$ for that.
