that could be a pretty long list. I will cover the big ones. There is approximately 20% less energy in ethanol than there is in gasoline. It is possible that the computer module notices the difference and cannot compensate in the air fuel mix adequately to get a clean, efficient burn. Ethanol is a corrosive, or at least much more corrosive than gasoline or blended gasoline. Over time, ethanol will eat through rubber based gaskets, seals and hoses. That will cause all kinds of problems for your car from the fuel pump, right down to the injectors.
YES!!!!!YOU SHOULD NEVER RUN A VEHICLE ON ETHANOL THAT DOES NOT SUPPORT IT (HAS A FlexFuel LOGO ON IT!)THIS WILL CAUSE EXTREME DAMAGE TO YOUR ENGINE!
It is possible for the check engine light to come on in a Pontiac Transport when using ethanol gasoline because it burns hotter than other gasoline. The check engine light might also come on if the oxygen sensor is bad.
If it is a new generation hemi (5.7, 6.1) it will come on because these are not flex-fuel vehicles.
If it has a downstream O2 sensor the check engine light will come on but if it does not the light may not come out. In most instances it will set the check engine light.
Yes it can.
No.
my check engine light came on and would go off, come back on again. when i had it checked, it was my gas cap, it was leaking.
why would u want the check engine light to come on. when its off it means ur engine is running fine. or the blub is pop
That would be a good problem to repair even if it's NOT causing the check engine light to come on... but I would suspect yes, depending on the manufacturer.
No, low gas cannot cause a Check Engine light to turn on. There would have to be a problem within the engine or the engine wiring for that light to come on.
would a bad battery cable in a 95 toyota corolla make a engine come on?
Why would you want it to come on. Its not on because theres nothing wrong with your engine.
