That is amazing👏🏼 I turned my LTFT from 10% to near zero👍 Before that, my Infiniti G35 have vacuum leak issue and thrown P0171 code. The LTFT level is around 15% which is no good. Then I fixed the vacuum leak and fuel trim level dropped from 15% to 10% and I am not really satisfied. After following the step in your video, the fuel trim is now prefect! Thank you!
I replaced my MAF in my volvo and wondered why it went from "rich" to "lean" Learned I had to reset the LTFT. I did this by disconnecting the negative terminal of the battery and letting it sit for 30 minutes.
Your car is always hunting for stoichiometric 14.7:1 regardless of how you drive it. If your fuel mileage has dropped you have another issue, and by using a scanner and monitoring long and short term fuel trims will be the best way to diag the actual issue within your engine.
If memory serves both the SES reset….as well as the Long Term Fuel Trim reset that I cover here, are outlined in the Nissan Field Service Manual. I appreciate you watching the video!
Interesting video. While the ses reset procedure and the fuel trim reset may be covered in the manual, the job of the ecm is to achieve stoichiometric air-fuel ratio. I also don't think it matters to the ecm how you drive. It is a fact, however, driving "aggressively" will reduce your gas mileage and probably the life of your vehicle components
Most cars if you just clear trouble codes, even if there aren't any, will erase LTFT (Long term fuel trims) and the car will eventually re-learn/re-set fuel trims.
This works on Livina 2011? I have sealed all hoses with silicone sealant, in still getting 6km/L. I know the average is 8.4km/L. I'm getting frustrated.
As far as I know, only for Nissan. It was outlined in the Nissan FSM (Field Service Manual), so that is the only vehicle I know it will work on. And even then it is only on the Sentra, Altima, Rogue, etc…of certain years.
I have looked for information like the one in the video, resetting the LTFT, but my question is if it would work for other models, makes and years of cars and trucks.
Not sure since it is a different manufacturer. I am confident this would work on Nissan, Infiniti, etc…but applying it to an American automaker…I am just not sure if they have the same tricks, etc as it relates to their ecu’s. I can’t imagine it would hurt anything to try it since the engine isn’t running, but I just don’t know for certain.

that worked for me, thanks for your help, my car is a chevy volt 2011
You're welcome!
I don't have a mass air flow..only map sensor...what should i do......
Can you do this with a scan tool just reset the code or clear the code.

Holy what an obnoxious reset method! I'd get a $30 scanner after doing that more than once

Will this work on a 98 Silverado?
This is only for Nissan? I have a toyota sienna. I should be getting more than 19 in florida. Use mostly highways when travel as well

Disconnect ur car battery for 24 hrs. It will reset ecu
About 30 mins is needed
actually 5-20 minutes
I have looked for information like the one in the video, resetting the LTFT, but my question is if it would work for other models, makes and years of cars and trucks.
Will only work for Nissan’s as far as I know, and only between like 2004-2016 with the 1.8 and 2.5 engines.
Will this work on 2003 chevy suburban 5.3 engine
I don’t think so, but I can’t say for sure.
@SMR TACTICAL would this work for jeep wrangler JL

wish i could do that for sentra 2005
If it has the 1.8l engine (qg18de) or the 2.5l engine (qr25de) it should still work for you.
@@SMR-Tactical i found the problem and fixed it. all fuel trims normal now.
The pedaling isn't necessary at least in a 350z
That’s good to know. I appreciate you posting that Ryan! Hopefully that will help others with a 350z as well. I appreciate ya man!
