Before opening this thread I checked alot. (For Not to make alot of same threads)
But please Help me about:
ECU flashes 7 and 6
I understood that TPS and ECT problem.

My problem is :
Cooling FAN never stops. (When I remove the cable from ECT it stops (I thing it is ECT )
And Temp Gauge shows 0 everytime .(Because Cooling fan run)
But I do not know What happened to this ECT before .
People says :
On the cylinder head and Below this distrubitor they are 2 sensors
One is small one is BIG wHICH ONE IS ect AND:

If the ECT sensor The bigger one MAY I HAVE A PICTURE ?
Because The ECT is (SOMEONE SAID IT IS DIFFERENT) he told this is not integra´s ECT someone put another not accepted one.
It has Only one CABLE CONNECTION .ECT has got 1 pin only.And It has no plastic cover and no plastic plug .Only IMAGINE that , like speaker systems + or - connection . And from system only one cable is coming (I have not checked yet maybe that 2nd cable is somevhere inside of this alot of cable )

But people says NO .
ECT sensor has got 2 PIN .And says again 2 cable must be arrived from ECU to ECT sensor
Please someone can show me the picture of ECT and which part number should I use. And please Another picture which shows ECT on cylinder head.
Thank you

The ECT sensor has two lead, red/white and green/white, it has nothing to do with the rad fan, [cooling fan].

The ECT switch has either two leads, yellow/green and black or just the yellow/green, it controls the rad fan, [supplies a ground to rad fan relay]. 94
