ECT, ecu test question (Yamae)
Ok I removed the connector from the ecu on a 1990 LS400 and used a scope
and got a similar tank circuit type out put, is your test done without disconnecting the connector?
I didn't really want to pierce the insulation.
Here is a similar scope view.

Tank circuit?
Where is it in the ECU?
I don't quite get what you are writing.

On the darker wire that connects to the engine coolant temp sensor, that is with key on and engine off (very similar) wave form I got. Time base change just increased or decreased it of course, no multiple pulse train. When I can I will check it out better, I had other important things to do.
Its not what I expected to see.

The ECT line circuit is completely different from a tank circuit and it's quite strange to me to introduce a non related Youtube link.
All you need is just to measure the ripple level of the line and judge.

Me? And actually saying that sort of thing may get you banned.
If it was my website, I would do the King Solomon thing, and do to others what
you wish to be done to yourself. And not saying he said that.
