Greetings all. I bought a Nigerian used 2012 4plugs Honda accord lately. It consumes a lot of fuel, scanned it and it showed no catalyst and bad O2 sensor. I was told a make shift stuff could be constructed into the catalyst chamber. I accepted and paid 28k for it and yet it still consumes the fuel.

Secondly, i observed that when I turn on my engine, the power steering fluid inside the oil storage boils and spills out. Such that it has now dried.
Please, I am a total Honda novice, I was using a 2002 Toyota Solara before upgrading.
More so, I bought it because of the good comments of Honda users here.
Kindly advice me on a permanent cost effective fix on the fuel consumption and how to stop the power steering oil issue.
Thanks as I expect your remedies on the above.

1. Try replace the catalyst. Most especially the upper one. But if you have money u can replace both I. e upper and lower. Also scan the car for possible error code. O2 sensor and stuff.
But I assure you if you can get it fixed well the car na machine. Muscle can never compete with am
As per power steering, just buy new one. If to say u r in place like north mechanic over there are Honda gurus, but if you are not, just replace it.

You didn't specify if it's a v6 or 4 cylinder vehicle.. . if it's a v6, you will definitely have a little bit higher fuel consumption than what you had with your Solara...


Start by replacing the 0xygen sensors..then have an expert check for the long term and short fuel trims... Have your fuel system checked and cleaned where needed, with parts also replaced with matching parts where needed... throttle body, injectors, plugs and their cables, etc.


Then check your revs while driving.. The higher the rpm the more the fuel consumption.. For some strsnge reason, a month or so after I got my 2010 Accord v6, I noticed that its revs were very high in relation to its speed, leading to ridiculously high fuel consumption.. MAF sensor was certified OK, no vacuum leaks, timing checked OK, no smoke from exhaust, yet bloody car was doing 4k rpm cruising at 60 miles per hour..

One mechanic finally told me to swap ECU and see if there is an improvement... 1st ECU that was swapped in, same 2010 Accord v6 started chilling at 2k rpm while cruising at 70 miles per hour.. Its fuel economy practically doubled and car became whisper quiet and smoother than before..it's been more than a year now, and Car is still as quiet.


If all else fails, and your rpm is still on the high side, try an ECU swap

As for your catalysts, they have nothing to do with fuel economy.. Scrape out all the gunk in there and install a spacer if the Catalyst code worries you

As for your power steering, have it checked by a power steering specialist.. There are mechanics whose specialty is power steering...

OK, thanks, I'll attempt changing catalyst and the O2 sensor.

I'll also ask a mechanic to check it out, because the car is slightly loud.

I [b][/b]think it was my fault, I used a fake oil instead of the Honda recommended oil, according to a post here, fake oil causes foaming and spill. So I'll try the Honda oil tomorrow.

Thank you very much, this advice is more than enough.

I can help u fix your car

Thanks, but I'm in PortHarcourt. I just wanted a guide on specific things to fix.

if ur power steering reservoir is boiling it means there is air in the power steering system, u need to see a mechanic to bleed the air out, there is a special procedure for bleeding it.

Please, for the sake of your engine, remove all the stuff and whatever they put inside the exhaust. Those things will block the exhaust leading to complete engine failure.

The mesh wires your mechanic put in there have little or no effect on your fuel consumption.

Thanks as well, Sir. I'll comply to your directive.

This is a very simple issue, first of all remove those rubbish which was constructed inside the exhaust and leave it empty, because the engine will breath freely without it and then change both Oxygen sensors down stream and up stream. Once you do that your car will be fine. I had exactly the same issue with you and ever since i remove the catalytic converter my car was very ok and it's more than 4 years now without any performance issue

Thanks for your input as well. It is good that I'm also learning from your rich experience.

Hello OP, I’d advise you to just get another pump, Honda’s aluminum pumps are very fragile, contact luvinghubby or go to oyingbo if you’re in lagos, fixed mine twice before I decided to change it, cost 55k with OEM fluids as at august 2021. As for the other issue, ditch the catalyst, install a spacer and most importantly change both o2 sensors, original denso goes for 28k each. The car is stuck in open loop, thus burning more fuel because the oxygen fuel ratio is off, have a qualified tech scan and clear the error codes afterwards, the difference would be clear as night and day.

Thanks as well, I'll face the car repairs from next month, I'm already exhausted.

1st, like others have suggested, replace catalyst with genuine one and remove the wire mesh installed in it. You would choke your engine with the fake catalyst in it.

2nd replace defective O² sensors with genuine ones.

Several other issues could be responsible for the high fuel consumption (let's assume it's consuming more fuel as claimed).
Bad driving habit, mechanic or mechanical error, electronic error, are some of the several reasons for poor fuel economy.

Take car for a comprehensive scan and read fuel related live data after replacing catalyst and O² sensors to ascertain what's causing the spike in fuel consumption if it still persist after changing necessary parts. Remote diagnosis would be difficult and near impossible.

Nigerian abused car comes with all the problem that made the owner sell it. The first time you take a car to a mechanic is the beginning of the end.
Forget about catalyst straight pipe. Power fluid is the wrong type that is why it is boiling pot Honda specific fluid in there.
Always scan your car before fixing and only fix what the scan says

Updates: I was able to remove everything from the exhaust, emptied the power steering pump and refilled with an original Honda specified oil.
Oxygen sensors were replaced with working Belgium grades.
Throttle body and maf stuff were cleaned with caburator cleaner. Fuel pump and filter were totally cleaned out.
A new air filter was installed, gentlemen.
For the past 3 days I have been using fuel of #2500 with ac under terrible traffic conditions.
The car is indeed a piece of cake.
Thanks thus far!

What's the price range for the two O2 sensor please?

1: Please 2012 Honda Accord two front tyres are sounding like a tipper, i've changed bearing twice same thing.
2: secondly my car makes a loud rattling noise when i start it in the morning.
@ Gazzuzz, and others kindly assist.
