Hello, I have a 2000 GS400 with 68K miles, Runs great - love it...
I ran out of gas yesterday trying to get to the next exit and when I did get some gas and started it up the check engine light came on. Car runs like it always has but the light is on - guessing nothing serious but wanted to check. Thanks.!

 

The loose gas cap could be the problem. Remove your gas cap and re-tighten it back in (3-4 clicks should do).

 

Thanks. Tried that and it is on tight. Wondering if when I ried to re-start when out of gas it caused vapor/air problem with sensor causing CE light to come on.

 

Thats typical when you go to the last drop on the gs gas tanks. Remove the + cable and reset the ECU. And I really dount a loose gas cap will cause a cel in our cars since one time I left mine at the gas station and only realised it when I got home and still didn't have a CEL. PS if you check the manual it even says it in there that you shouldnt let the gas tank go empty.

 

after reading this... i'm definitely always gonna get gas when my light goes on. i had too many close calls haha

i never fill up full either... either between 1/4 and 1/2. that's just me

 

I will unfasten the +. Thanks. Yep. felt pretty stupid as I was standing along side the interstate for my first in a lifetime "out of gas" experience. ...I thought I could make it.....
