Please help i got the 0705 the sign only goes on when i the gas needle passes the last dash (about 3/4 empty)

 

Look up the code and see what it says. If you are almost out of gas when this happens... Does it go away when you put more gas in your car?

This is a "jackpot" DTC. It points to so many things you don't know what to check. It is often combined with another DTC which is more specific and therefore more helpful.

 

take it to a place that is able to give it the "smoke" test to find the location of the problem. i've had this CEL for close to a year now and i basically gave up.

 

Til you get money to fix this, simply fill up the tank before you get to that point so you won't have to see that code again.

 

This is in the stickies.
