Naa. That's you living in ignorance.

I asked you for the location of your ect2 sensor aka fan switch.

And you resort to insults?

jceesquare:
Naa. That's you living in ignorance.

So you still insist that the ECT 2 SENSOR and the FAN SWITCH are different parts on the 2003 - 2007 Honda accord vehicles?

Macmilla, are you seeing what I'm seeing from our able mechanic jceesquare here this morning? 👀

Conner44:
Plus for your updated information

The ECT 2 SENSOR and FAN SWITCH are one and the same part.

Please keep this in mind as our discussion progresses 👍🏾

I'm still waiting for the location of your own fan switch.

No.
ECT sensor and fan switch are not the same. They don't even look alike. And they do different jobs.

Fan switch is an on-off switch. It just closes a circuit at a particular temperature, thereby switching on the fan at that particular temperature. In cars that have fan switch, the brain box does not receive input from the switch and the brain box does not control the fan.

ECT sensor is exactly what it is called, a sensor. It senses the temperature of the coolant in the radiator and sends the information to the ECU. The ECU uses this information to determine the status of the engine and then know when to turn on or off the fan.

I hope this is clear.

Fan switch is an one-off switch. It just closes a circuit at a particular temperature, thereby switching on the fan at that particular temperature. In cars that have fan switch, the brain box does not receive input from the switch and the brain box does not control the fan.

Very apt. Now you've made it clearer for me to understand. They both control the fans but in different ways. One via the brainbox and the other it's own means. I've learned that one today.

Now I wanted to know how jceesquare's vehicle controls it's own cooling fans without either an ect2 sensor or a fan switch attached to it's radiator . . .

Is it such a terrible knowledge to seek? 🤔

jceesquare:
This was my initial quote. I made emphasis on the ECT 2 sensor.

This was Macmillan response to my quote

Then this is your cheeky response.

My stand has always been that not all 7th gen Accord has an ECT 2 sensor.
It's either you have compression issues, or you just want to act ignorantly.

I'm actually confused, bro.
Are you saying you do not have ECT sensor on your i4 2003 accord, but have fan switch? Or that you have none at all?

It's like he is no longer interested in educating us.

Well, his lack of an explanation concerning this issue points to either of the below 2 options

1. He has no thermostat in his engine

2. He has a thermostat but his cooling fans run directly via ignition

I see no other reason why he reacted the way he did apart from the options above (which are normal in nigeria today by the way)

Oh well, maybe some other time he will indulge us. For now let me be happy I have found out the differences in those 2 switches which are mounted on the exact spot in all 2003 - 2007 4cyl honda accord vehicles

Macmilla thanks for sharing 👍🏾

If you short the two wires going to the FAN SWITCH, your fan will be on permanently and your ecu won't even notice until something else goes wrong.
But any short on the wires to the ECT sensor will throw a code instantly.

Yes, they are mounted on the exact same spot. But if you noticed from the picture I posted, their thread size is not the same. What that means is that a radiator that came with a fan switch (2003-2004 radiator) can NOT accept an ECT switch cos it won't fit. So it will not work on 05-07. Their plugs are also not compatible
The radiator meant for ECT sensor (05-07) will also not take a fan switch. So it will not work for 03-04.
I learnt this the hard way.
While the v6 radiator doesn't have anything at all.

A lot of kazeems do not know this.
So sometimes they buy v6 radiator for i4 and end up not connected the ECT wire.
Or they buy the radiator with fan switch for a car that needs ECT. And when the connection doesn't fit, they just hide the wire away and tell you "it doesn't do anything.

More knowledge for my consumption here. Nice job man. 👏

Okay good. Now I know why my own fan switch never threw any code when it's wires were cut off by an overzealous mechanic before.

So if I had the ect2 sensor I would have had a check engine light?

Cryomancer:
Abeg how do you guys measure this fuel consumption and MPG whatever??

I'm terrible at mathematics, maybe that's where my problem is even coming from. Because the last time I checked, you have to calculate Trip A and B whatever whatever, omo na so I just run oo. I use my weekly usage to calculate my fuel consumption now🤣🤣🤣🤣🤣

I've explained this here on nairaland before.
Fill up your tank to the brim and reset your trip counter. Drive the car till your fuel is about to finish and not how many miles you have driven. Fill it up again and note how many litres it took to fill up to the brim the second.
This will give you how many MILES you drove with that amount of fuel.
Dividing the miles with the litres of fuel gives you how many miles you drove with each litre.
Most trip counters are in miles and not kilometers. So be sure what you have. If yours is in kilometers, you will have how many kilometers you drove per liter.
If this calculation is too much for you, just drop the numbers and we will do the calculation for you.

Exactly.
If your car is 03-04, you will not have a code. But if it's 05-07, you will get a code.
Those kazeems are fond of cutting that wire to short them to make the fan permanently on.

Macmilla:

Thanks man. You're too much.

Don't mind jceesquare, I will keep an eye on him and his doings in this section.

Imagine a mechanic driving his own car without thermostat or has his cooling fans working directly

Bola4boy:
Also, my car no get catalyst. Should I get the spacer or buy China catalyst.? My fuel consumption is about 4km per liter for city drive. Sometimes less than that

Are you sure this is 4kilometres or 4miles?

Conner44:

And you resort to insults?

Show where I insulated you and I will apologise

I guess he wants to just throw tantrums and not ready to unlearn what he has learnt overtime

Macmilla:

I do not have an ECT 2 sensor.
That's what I've been typing all this while.

jceesquare:

It's not a matter of the insult. WE ARE ALL HERE TO LEARN both you and I and even Macmilla

But when you make statements and run off like the way you did you leave room for assumptions and other stuffs that follow.

Nairaland is not a place for such especially as you're a mechanic who comes here to get business.

Remember I've once told you in the past that I am not a mechanic, I am a regular car owner who happens to love DIY repairs on his own vehicle.

Now, are you ready to tell us the truth about your vehicles missing ECT2 sensor/Fan Switch?

Well I believe you know we all have a life outside here and don't live and breathe here.
I made a video, you can check if you wish to.

jceesquare:

In your picture there is absolutely nothing plugged into your radiator.

So what switch do you have? 🤔

Stop beating about the bush and be open plus plain with us here

Macmilla:

I guess you have the patience and time to elaborate my initial claim that a faulty ECT 2 sensor or any shenanigans done to it will always throw an instant code.
My emphasis has always been on the ECT 2 sensor and nothing else.

I see you just want to masturbate over what you do not know.
For the record, I owe you no explanation to how things work.
Your initial response to my post was a turn off to me.

Too early for that.

Here is another video for you Conner44 that not all 7th Gen Accord has an ECT 2 sensor

I see your video.

I acknowledge that all 7th gen accords do not have an ect 2 sensor

What I asked from you was an explanation . . . A VERY SIMPLE ONE TOO . . . as to why your own 7th gen 4cyl honda accord HAS NEITHER A FAN SWITCH OR AN ECT 2 SENSOR connected into its radiator.

It is a very simple question, why drag it out so long like this if indeed you're not trying to discombobulate me

Macmilla:
Are you sure this is 4kilometres or 4miles?

I use honda accord 2005. What do you think sir? Google map distance is also in kilometers nah

Bros, pardon my ignorance, but you are still confusing me. This video still didn't clarify things.
Yes, I agree you do not have ECT 2 and I already mentioned that 03-04 have fan switch and not ECT on the radiator.
But my question is very simple, do you have anything on your radiator? If yes, what is it?

jceesquare:
I will do a video and send later.
Macmilla this is a video I made just now showing that the ECU takes fuel trim reading off the secondary oxygen sensor (B1, S2) on the 4 cylinder 7th gen Accord without the MAF sensor.

You no talk anything about this video after showing evidence again ni?
