Same dilemma here 2 years ago I had been trying E85 ethanol with my Flex Fuel kit from PRL Motoports, with correct ratio. Now i'm no longer using E85 mix just regular 98 Petrol. In Australia here, gas prices have gone up and was it possible im thinking that the mixture of fuel in the lines can cause blockage in the filter system? i've checked my other parts including the fuel injectors but not the fuel system parts under the vehicle. if that makes sense, next is to check my fuel filter
Sir my car have the same code but I already changed all that parts and still running rich I'm thinking to replace the purge valve canister do you think that can cause the code?
06 civic coupe ex auto Got an ac issue ,won't get signal from sending unit checked fuse checked relay and pressure sensor still nothing brand new compressor good working turns on manually from engine bay and just filled freon and oil ,someone said could be ecu ?
Great video I still have this problem tho and keep getting ripped of at the garages so tried doing this myself been almost 2 years now still with this problem everything else on the car is new car struggles to drive badicly starved it feels. It feels like it wants to go but then gets held back go stop go stop like feeling when I'm driving need help
I've been REALLY racking my brain for this P0172 code. I have all new sensors since I bought a Japan engine in April 2022. I've replaced EVERYTHING for the emissions systems too. Then my 99 Honda accord started to have misfires after getting gas. I was told to check for an evap leak. That test came back good. Then was told two of the 4 fuel injectors need replacement. Found out the hard way that my mechanic was too lazy to switch out the fuel rail, and exhaust when swapping out my bad engine for the Japan engine. So I reluctantly bought fuel injectors from Ebay since they were the ONLY injectors to fix my Japan engine. After putting 30 miles on the car after the fuel injector replacement, that's when I got the P0172 code. Any suggestions? I can't keep throwing parts at this car. I've been replacing parts for 8 months. After each part is replaced, a new engine code appears.
my honda error code turns on and off and has been doing this since i got the car around 20-40k miles. do you think with it randomly turning on and off, its more likely a faulty sensor?
how does having a clogged fuel filter cause a fuel rich code? Intuitively, I think it would be a lean code because it is not sending enough fuel because the pressure is low.
Not sure why but as per the Honda Workshop procedure, the first thing to check is fuel pressure which could be both too high or too low.... And the 2nd thing to check is the EVAP purge valve which it holds vaccum
@@juliosalcedo6737 look for your injector cause i put federal emissions injector into my California emissions thats why i got only one code p0172! If you have the old injectors clean those snd put it back mine is gone!

Man this is such a good video, I could never be a mechanic. You literally have to look so hard to find the issue😭😭

Just clean your MAF sensor and replace the O2 sensors 98% of the time that’s all you need to do
Great vid man
2017 Civic Si, my OBD II is reading N/a on my MAF, does that mean it’s bad or do I just not have a strong enough scanner

I recently
Changed the catalytic, could be a sensor?
I have the same problem, I've changed the tps, aic, iat, purge valve, injectors, ive come down to a vacuum leak or my fuel pump pressure is bad.

I have replaced the map sensor. Bank 1 & 2 o2 sensors. Did a smoke check for vacuum leaks. No leaks. Looks like fuel pressure is next.
i had a question. my check engine light turned on and it came up as “fuel to rich”. any ideas what can cause that??

I have the same issue turns on and off I have an Honda accord
Vacuum leak will not cause this code

Is it possible with this error code it could be a plugged catalytic converter that would need to be replaced?
did you ever end up finding out? I'm getting P0172 right out the gate, then P0420 and P0430 pop up shortly after
@BRANDONGONE92 you 100% need a catalytic converter. P0420 is always a cat
Maf sensor,o2 sensor, spark plugs and still got a p0172 code in my 2017 honda pilot ex, dose it have fuel filter in between?
It has a fuel filter somewhere in line
If you know there is no vacuum leak, then the next item to check, would be the fuel injectors.
Is there a fuel filter in honda civic ep2 and where ive changed the fuel pump 🤔 and still got the code po172 rich aswel help
low fuel pressure cause fuel trim to push towards lean side not rich side.
He didn't mention gasoline in the oil. When the engine gets hot, the PCV will suck up the vapors from the oil and throw a code if the oil is bad😊
Have this code on my 08 pilot for a whole year and cant figure it out as yet
I've tried all those options but my 99 accord still has this code. Could it be the ecu?
While possible, a computer problem is rare. A P0172 code can be hard to troubleshoot sometimes, even for experienced mechanics.
The nafta cap can be the problem
I’ve installed a cold air intake and got this engine code, would i still have to check all of these things?
Probably not installed properly
same for me as well.. did you end up fixing it?
@@michellebautista8511 mines is installed properly asf its so simple…. i just honestly think i need a tune because the cpu cant control its fuel trims
@@johnnydope-sz8fwI had to reinstall my cold air intake and tighten some stuff up then all the codes were removed
