Bola4boy:
Thanks MacMilla for your analysis. I read your post sometimes ago on how you tackled the issues with your honda accord 2005. I currently use same car and I'm battling with high fuel consumption.

I believe the sensor on the radiator is ect sensor 2( it's absent in my own radiator) but the fan works when engine gets hot

Another ect sensor at the engine area but our Kareem usually call it cold start. Now, my car rpm is unstable but when ever I remove this ect sensor, it balances but radiator fans will start working immediately and temperature guage won't work. I have replaced the sensor but same issue. I have a Bluetooth scanner, the codes I see is the one for downstream oxygen sensor and ect sensor 2 ( radiator own)

Pls help me. Pls help me pls help me. Rewire said I should change brain box for the rpm to stabilize but I no gree.

I'm ready to change the radiator tomorrow but what about the unstable rpm. And what other things should I do to save fuel?


I need help

Your car has been abused electrically, get a competent rewire to look at it.
Also get another radiator for your car that comes with the space for a secondary ECT and get it connected.

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

Change your downstream oxygen sensor and get the ECT 2 connected.
The downstream oxygen sensor for your car does more than just monitoring the oxygen level in the exhaust.

I will indulge you this once.
Pic 1 is a 2003 Honda Accord with a V6 engine and without an ECT 2 sensor on the radiator.
Pic 2 is a 2003 Honda accord with an i4 engine and with the ECT 2 sensor on the radiator.
Pic 3 is also another 2003 Honda Accord with an i4 engine and without an ECT 2 sensor on the radiator.
Those cars came that way and and not modified in anyway as confirmed from a live data stream.
The fact that you've not seen it does not mean it does not exist.
Get your fact right and stop misleading the public.
Abi you go argue say not all of them comes with a MAF sensor as well?

Stop showing me pics of abused accords to prove that a vehicle that has its fans still running via the brainbox isn't being controlled by an ect sensor.

Why not show me factory wiring diagrams to prove your point?

Besides, the MAF sensor is another matter because it controls something else entirely in different years of the accord so no need bringing such into this discussion.

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🤣🤣🤣🤣🤣

And the Live data that does not have provision and not showing the ECT 2 sensor is also sign of abuse?
All 3 cars I posted have zero codes on them. Says alot for an abused car.

divide the lkilometer you traveled by liters of petrol you bought. If your tank dey half Guage. Buy 20liters for instance and drive the car till it gets to exactly half Guage. Divide the kilometers covered by 20 liters you bought . So from there, you know the consumption per liter

I think you simplified it with this explanation of yours.

I'll try it out and see what I get.

Thanks

Put the liter of fuel bought and the distance you covered before the fuel got to the level it was before refill. The site will help calculate your fuel economy with the information you provided.

This is exactly what I would advise.

Please can you tell us what else the secondary (downstream) HO2 sensor does. Evidence will be appreciated.
In all the research I've done on Honda, all evidence point to the sec HO2 sensor being purely for emissions control. It monitors the efficiency of the catalytic converter and nothing more.
The primary (upstream) HO2 sensor, more appropriately called Air fuel ratio sensor, is what actually monitors and adjust air-fuel mixture in the engine.
Please if you have a contrary opinion, give us your source, so we see for ourselves.

Bros be calming down.
All 7the gen accord with v6 engine do not have any sensor on the radiator. Both ECtlT sensor 1 and 2 are on the engine. (Picture 1)
All 7the gen accord with i4 engine has either Fan switch (04-05) or ECT sensor 2 (05-06) on the radiator. (Picture 2)
If your i4 7th gen has nothing on the radiator, then it is either Honda is hiding something or you need to know your car better.
If your car is actually a i4 with nothing on the radiator, then educate us (with evidence) on how the car is controlling the fan.

Thanks for this thread. For me I use the EOD and sometimes ago when I fuel my car, I get the PO420 "Catalytic Converter below threshold bank 2" I have no catalyst. So does it mean I have to get the Chinese one or change oxygen sensor. My fuel economy not too good. Though no CEL anymore.

Cryomancer:
This catalytic converter issue is one topic that i find really amazing especially in Nigeria.

Series of opinions have been gotten differently on it.

Here isy submission:

-Catalyst is purely an emission/climate control initiative

-Catalyst in my own opinion helps with conservation of fuel because when your air/fuel mixture is correct, the ECU doesn't need to pump more fuel into the engine to gain optimum performance. However I think this relates to vehicles that have both upstream and downstream catalysts

-Nigeria has a country doesn't have a strict emissions control body, therefore de-catting is indirectly encouraged. Also due to the price of catalyst in the market, you can get spacers as an alternative for catalyst but finding the one that works is a task these days. In my own case, I got a Chinese complete Catalyst, it does the job and the check engine light isn't showing on my dashboard but it gets corrupted after some time (2yrs) and then start to show check engine light.

- Side note: When using an original complete Catalyst, it's also prone to getting blocked after few years and when not detected early, it causes serious damage to the engine if not careful.

My initial message was that not all 7th gen Accord has a switch or whatever you want to call it on the radiator, but guys countered it until I sent pictorial evidence and now the narrative is changing.
The second Accord without the ECT 2 sensor is my personal car and it has zero codes on it.
I've checked the data stream over and again with my scanner and other colleagues scanner and there is nothing like ECT 2 reading showing on it.
Abi you want make I show you video of the data stream?
Modified: Just read your message again and saw what you meant by a radiator switch and ECT 2 sensor.

From experience working on 7th gen Accord (especially the ones without MAF) that downstream oxygen sensor does more than emission job and also contributes in the fuel trim.
Do you want video evidence for this as well?

So does your own vehicle STILL NOT have an ect sensor? I think it's a 4cyl accord right?

Plus there's a reason I asked you for a factory wiring diagram as proof before, if you do not have one I suggest you try to source it as it seems you work on these type cars frequently 👌 the 4cyl eod ect2 sensor does not throw a code once it's faulty on these kinds of cars.

My own does not have an ECT 2 sensor.
This has always been my argument.
All cars (at least modern cars) comes with at least 1 ECT sensor, but not all cars have a secondary ECT sensor and my Accord is one of them.
So back to my statement. Not all 7th gen Accord has an ECT 2 sensor on the radiator.

Okay good. Let me rephrase the question Macmilla asked you before . . .

So, does your vehicle have its thermostat intact? If yes pray tell us how your brainbox is able to control your cooling fans without an ect 2 sensor attached to your radiator

I am here to learn something new from you today

jceesquare:

Okay. I'm learning from you today

1st read his post again like I did and read mine then tell me if you now understand what a fan switch is and what an ECT 2 sensor is and what they do.
Then I'll explain better what you seek for

Okay. I have reread the posts.

Can you tell me the location of the Fan Switch on your own eod?

Conner44:

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

jceesquare:
Not all Accord of that generation comes with the ECT 2 sensor.
I also have a 7th gen Accord without the ECT 2 sensor.
If yours comes with it, then I'd suggest you get a radiator that's compatible with it as that sensor helps with regulating your fans speed.
For the cold start, I assume you're referring to the ECT 1. Scan the car for possible code related to it or test the resistance of the sensor with a multimeter.

This was Macmillan response to my quote

Macmilla:
2003 and 2004 Honda Accord has a fan switch on the radiator.
2005 - 2007 has an ECT sensor on the radiator.
If yours does not have ECT sensor, then it must be 2003 or 2004, or kazeem has made love to your car.

Then this is your cheeky response.

Conner44:
Not true stop misleading the public and do proper research 🙄

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.

jceesquare:

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.

At least I know what I know and see on my live data. If you choose to live out this discussion in ignorance then it's fine.

Macmillan and conner44, 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.
