4A-GTE: Check Engine Light

[JBQ]

Hi there,

I've just converted my 4A-GZE (supercharged) into 4A-GTE (turbocharged) with one problem i.e. Check Engine Light lights up when I'm cruising for about 20 minutes at about 3,500 rpm. This Check Engine Light will disappear when I off the engine. This prevents me from checking the engine error coding.

After restart the engine, I have to cruise again about 20 minutes to see the Check Engine Light again.

Anyone has met this problem before and what causes it? - THANKS.

Your ECU or Wiring Got Problem Bro, Check Your ECU LA

May be the ECU problem whereas the wiring is minimally altered from original.
