That's pretty neat considering the 1NZ doesn't have EGR because of VVT-i

Exhaust gas recirculation ... Isnt it ?

And thats what the scan gauge was telling ... And im just confused abt ur saying EGR is not there ins vvt-i ??

CTScott · 10-21-2014, 08:04 AM

He actually does have EGR on his, as it is a Japanese Vitz.

What is the code that you are reading regarding the EGR?

There is an exhaust gas sensor (89412-35020), and the EGR Valve assembly (25620-21010) that are the typical failure components for the Vitz EGR.

Bluevitz-rs · 10-21-2014, 08:13 AM

I apologize then. When I read up on the 1NZ-FE, it said EGR was eliminated because VVT-i can create its own exhaust gas recirculation with valve overlap.

AND, every 1NZ I've seen at importers doesn't have EGR.

Im done with the EGR code ... Had to completely transfer EGR mechenism from stock headers to my custom made ...

salmanghiyas · 10-29-2014, 08:05 PM

But the big problem is here now ....

P0171 system too lean

As ive already stated im with followings mods right now

1zz tb
1zz IM
Custom headers
Custom down pipe

And a blitz SRI ...

Im attaching some pics for clearity ...

But i think this CEL started coming after the blitz SRI ... Currently i have converted the SRI into CAI ... And the cone is mounted out from the passenger's side head light ...

Another thing is that ... Im getting this system too lean CEL only on idle ... On normal driving or on wot .. not CEL's

Afr when SRI was
Idle : 15 to 16
Wot : 12.6

Afr when CAI was
Idle : 16, 17, 18 and a point was 19 as well
Wot : 11.4

Chk plz

mitchell12 · 10-29-2014, 08:40 PM

Something to do with your AFM no doubt. The tubing that runs into it affects how it interprets the airflow and if it thinks more air or less air is coming in than actually is then you will run rich or lean respectively.

My opinion anyways.

Actually on second thought it could have to do with your EGR setup I think too.

Is that Blitz made for the Yaris? It looks larger in diameter at the MAF than it should be.
