AE86 3SGE Beams Dual VVTi CEL not working

Postby Chrisae86 » Wed Jun 04, 2014 5:33 pm

hey guys,

i have a similar problem as this old post from ( Xgrapher )

When we encountered the electronic throttle problem - meaning the accelerator cable didn't open the throttle until it reached 80% (limp mode) - first thing we thought was to read the dtc codes. To do this we connected one end of a test lamp to the W pin of the ECU and the other to ground, just as is done with all other toyotas.

But guess what, nothing!

It's been two weeks we are trying to find out why the check engine lamp wouldn't work and still no success. We made sure all grounds were good to the ECU, tested the 12V batt and 12V ign and everything simply seems to be perfect.

I remember having same problems with 1JZ ECU with big grips (4 rows). I solved it by giving 12V to all 4 pins as required by the ECU and the CEL started working.

In this case, I have run out of ideas so please please please if someone could help.

Also on a side note, if somebody has faced similar probs with electronic throttle share with us how you resolved it.
