Bad Fuel Pump test Yamaha yzf R6 part 1 (Error code 50)
Вставка
- Опубліковано 29 бер 2024
- I've been having this mysterious issue since I bought the bike. I changed the spark plugs, cleaned the air filter and checked the throttle body but couldn't solve nothing.
I bought this low cost Chinese fuel guage to check the fuel line, and I found out why the ECU always cut out the power whenever I'm going uphill on the Twisties.

Nice and informative video, thanks for making this video, very helpful.
Hi bro. Thanks for the video. I have the same problem with my R6 2008 : full gaz at low rpm on track and the engine downs idle and the throttle have no reactions.
When I enter to diag mode I see this error in d61 : 50.
Tho it seems to be the same problem. What do you think of that ? Could it be the fuel pump ?
Thanks.
(And sorry for my language, im french)
Hi bro. Thanks for the compliment. D61 is the malfunction history codes of the past. 50 is all about the fuel system.
I can't say definitely that, it's the fuel pump that's causing the issue. My advice to you, would be to perform the same test that I did on my bike.
The test though is referred only for the fuel pump efficiency. Other components of the fuel line system have to be checked separately if the pump is good.
@@Geed94 thanks. If it's not that, could it be TPS sensor ?
It might be the TPS sensors. Check if the sensors resistance are according to specs.
My bike TPS sensors specs are out of order but after the new pump installed, there's no issue.
A bad fuel pump filter can cause this problem too.
@@Geed94 hi bro. Thanks for your time. Unfortunately I've just changed the pump and the filter on this week, and I've just been testing the bike today and the issue is not fixed.
The error code 50 came back instantly when I make full gas on low rpm. No problem with high rpm, but with the low rpm at full gaz, the issue appears instantly. So I don't understand. And I have track day at Le Mans in less than 2 weeks so I think I won't succeed in fix the issue before. It's sucks
I'm sorry for the bad outcome after the pump changed. It's a very tricky fault to say the least.
I went to the Yamaha dealership and explained my issue to the technician, he searched on the computer and told me, it could be the ECU.
I didn't believe him so I went ahead with my diagnostic test.
My bike fault that you saw in the video, happened only on that mountain road. Every other place it ran perfectly fine.
It's a very mysterious fault and my advice would be, test all the components that have to do with the fuel system and non. Stop replacing components without a proper diagnosis test.
I replaced the 4 spark plugs and filled the tank full and the bike was running fine. When the fuel gauges light came on the dashboard, the issue came back.
I'm having my bike almost a year now, but it took me 4 months to figured out the problem.
Do a lot of diagnostic test to pinpoint the issue. Let someone that's good at diagnosis help if it's overwhelming.
You got it, don't loose hope.
Yo bro i have a 2 stroke scooter i installed the black edition 21mm carb and the scooter bascically turns on for likr 3 seconds and just turns off like its not getting gas but the carb is full of gass
You might have the air closed. Adjust the air and fuel mixture for the carb and lastly check the spark plug
It seems that the air is closed and the carb is running only with gas. Open the air with 2 full turn from the closed position and adjust the gas. Too much gas is rich and it's not good. The carb can't perform well if it's not properly tuned.
