I am a new member and I am willing to get some help from.
My 2006 Honda Pilot/90kmiles has misfire P304, p305, p306 and vtm4 light on and both fan do not turn on.

In the purpose of solving a cooling fan problem in my Honda Pilot 2006, I have been watching some of your videos on YouTube, they help me a lot but I still want to solicit your help if you don't mind.

My both fans (cooling and ac fan) don't work. I made a couple of test of fuse, relay, fan motor... they all work correctly. Then I unplug the cooling temperature switches so that I could use a paper click to short circuit it ( to give the ground signal directly); but as soon as I unplug the two switches, the fans turn on if the ignition is on.

So I get lost, I am asking where the coolant circuit find this ground signal, that the ect sensor was supposed to provide.

Thanks for taking time to read it and Any help will be very appreciated.
