Hey…
Since we got AE111 Engine ECU Terminals

Why not I make myself the AE101 Engine ECU Terminals diagram …

Soo here they are…click image for bigger size…

AE101 Engine ECU Terminals (Manual)

AE101 Engine ECU Terminals (Auto)

P/S :
1) Please take note that above ECU Terminal pictures are for normal AE101, not for AE101 model 93.5…It’s a bit different…refer to the data table respectively…
2) For AE111…still on progress as need to know the wiring color…

Ever wonder what is inside our beloved VVT pulley

This what makes our Intake cam pulley advance by 30 degree with the help of OCV with the right manifold pressure, that received signal from ECU…

Thanx to DonnieB from hhttp://forum.9000rpm.net

===================================

Then comes in VVT-i system…
Hence…the VVT-i pulley
which looks something like this :

Open the 4 bolts…this is what you see inside…

The cover plate off. During normal start or cold start…system goes to fully retard…once on operathing tempreture…system can go advance n retard back when ever needed…

More info on VVT-i noise…
VVT-i internal parts and how it works…refer to this thread - Celica Forum

==============DVVT===============

While we are talking about VVT-i, lets talk about DVVT.
which works similarly to VVT-i…

Here some brief picture of DVVT system…

Thanx to otromen from myvi forum

Sensors Detail :
From top to bottom, left to right :

Water gage (water temperature sender switch) : 83420-20040 - AE111
Knock Sensor : 89615-22050 - AE11#
Oil pressure switch : 83520-35030 - AE101 and AE111
Oxygen sensor : 89465-19685 - AE111
Temperature switch (temperature detect switch) : 89428-12160 - AE111

The most troublesome sensor with faster wear and tear is the O2 sensor / oxygen sensor / lambda sensor…with life span 50k miles or 80k km…

Others…not quite sure…will try to find it…
