Posted May 26, 20241 yr Hi On my bike route today, unfortunately I went through an area with 109 F degrees. After filling the gas tank on that area, the gas gauge started to blink. The bike (FJ 09 2016) worked well, yet the gauge blinked all the way after I got to my destination, one hour later and with better weather. After a while, the flash stopped, and later started again randomly. After half a day, sometimes it comes up, sometimes the gauge is normal. The bike still runs fine, just the random gauge blink is a bit of a concern. This never happened before, and maybe the high weather temperatures affected something Any ideas?

May 26, 20241 yr Read your owner's manual: Likely the fuel pump is stuck or the relay is bad. Pull both and test, or take to dealer.
May 27, 20241 yr Author Today a was ridding almost all day. The flashing has been reduced to maybe 10 seconds, out of several hours driving and working normal. Seems that the problem it's being self - corrected as hours goes by after it's trigger, yesterday. What could have caused it? No idea... The only 2 facts when it was triggered, was extreme heath weather, and filling the gas tank on that weather.
May 27, 20241 yr Not sure what ethanol content is in your fuel in Mexico, but it's possible that you filled the tank too full so that fuel expansion caused the fuel sensor to think there was an error.
May 27, 20241 yr I think it,s impossible to fill too full, because, if you overfill gastank, gas just spill out through tank breath hose, which goes down near front sprocket cover.

Right, it shouldn't happen. But he mentioned extreme hot weather. When I say "too full" I don't mean overflow, I mean a normal fill plus a top off many people do. Commonly on motorcycles people fill while on the side stand, then stand the bike up and top off. So gas is cold as he's filling the tank, he fills it to full per the pump gun and then tops off. But it's 109F outside and his tank is hot from riding so the gas gets hot and expands once in the tank, but he's also riding so he's consuming gas as it expands. Fuel float/sensor can't figure out what's happening and throws the error.
