DIY - 1.8L 1ZZ-FE TB Connector Chip Swap - Page 13 - Toyota Yaris Forums

jkuchta · 05-12-2009, 10:00 PM

What code is the CEL associated with?

Also, for the people that are still having problems with the swap:

Are you guys using the stock Yaris gasket (the black O-ring with the "tail" and the partial mesh screen) with the 1ZZ TB?

If not...you should use at least the "tail" portion. The slot that the "tail" fits in on the intake manifold offers a totally open channel through which air will get in and cause idle speed "hunting" and CEL's. The channel is large enough to suck in any partially set gasket maker and give you problems such as rough idle and CEL's.

When I did the install I cut off the "tail" from the gasket and installed it in the channel in the intake manifold with gasket maker. Once set, the "tail" creates a nice solid plug for that channel, and I haven't had a single CEL since I made the chip swap....not ONE!

Well the CEL finally disappeared and it ran great for about a mile. and then this

Fuck this throttle body. Put the stocker back on and it is running great.

eii · 05-16-2009, 06:20 PM

Whaaaaaaaaaaaaaaaaaaat? Please explain what happened. I'm scared, I'm scared for my life now.

jkuchta · 05-16-2009, 06:35 PM

So what went wrong? Do you know what the CEL code was?

Please tell me step-by-step how you installed the 1zz TB so we can figure out what went wrong. I've been running mine without fault for a few months now...there's got to be something simple that can be fixed and will clear up the whole problem.

And eii, if you want to go for a ride in a yaris with the 1zz tb install that was done correctly, PM me.

CEL was gone. Car completely died and wouldn't even idle. Start it up and it woul ddie instantly. I used the original gasket plus gasket maker, I did the coolant bypass, I did the chip swap. I did everything it just didn't work out for me

That could be pretty much the 1ZZ T/B itself being the problem, try another different 1ZZ T/B or try the 2AZ-FE 2.4L T/B.

remember! failing is the beginning of success, it wasn't easy for me either

jkuchta · 05-18-2009, 01:35 AM

Bummer...

Do you know what the code for the CEL you were getting was? It may provide some clues as to what caused your problem.

Guys,
I've been following this mod for a while now,

If I'm correct the newer yaris models have electronically controlled TB. Well, I looked under my hood and see sort of like a cable running from the pedal to the TB, I can rev my engine by turning this swivel.

bieniman · 05-20-2009, 08:38 PM

O yeah forgot to ask.

Can I do this mod also to my , Vitz Rs 2001?????

enviri · 05-20-2009, 09:00 PM

dude! i was about to put it on! now im gonna have second thoughts or get garm's! jeez...i think there HAS to be something we're missing...a hidden variable thats affecting some of us...

Yes, this mod only applies to the Drive by wire system that is in the ( i believe) '05 and newer

doesnt sound like the TB unless a wire snapped somewhere.

Stocker works flawless though so it isn't a wiring issue.

I'm not 100% positive on this but the scion xa/xb owners have done a swap with an older 1zz throttle body which is drive by cable like yours. check the forums @ scionlife.com you should be able to dig up more info.
