So check this, my low fuel light will ramdomly flash, it is a steady pulse, doesn't seem to matter how much fuel I have, or don't have. Never seen this before..any ideas. It doesn't do it all the time, it goes off by itself, usually within a day, no fault codes.

 

Nobody????

 

i've never seen or heard of it happen. don't think this is even in the owner manual.

 

Fuel sensor may be going bad or could be due to insufficient tightening of the fuel pressure sensor or loosening of the senor nut to the delivery pipe. I know that there was a recall for leaky fuel senor gasket awhile back. Are you noticing or smelling any raw gas. Other than that not sure what it could be.

 

No not at all.....everything seems normal, except for the occasional flash....totally ramdom thing. I talked to a Lexus specialty shop, and the local dealer, both said thed never heard of such a thing. The light was actually flashing when I went by the specialty shop....a head scratch and a 'mmm..." was all I got. I would guess if something were starting to loosen, the problem would get worse as time went on IDK

This has to have happened to someone before...as I said, it hasn't effected anything, but not knowing is pissing me of.

 

same number of flash every time?

here's a crazy test, go to a big empty parking lots and drive in circle. do both clock wise and counter. should create an uneven fuel level see if this recreate this flashes.

 

Same flash every time, like a ticking clock. I tried the driving in a circle thing...nothing...except for folks looking at me funny...
