Why does my check engine light come on when I use E85?
Flex fuel vehicles can use any concentration of ethanol up to 85% which is known as E85. If higher concentrations of ethanol are present in the fuel tank of your non-flex vehicle, performance and drivability issues will result and in turn, the check engine light will illuminate.
What is in E85 fuel?

Why does the VSC light come on in my Toyota Sequoia?
Toyota has lights for all sorts of systems, yet is the gas cap is not on properly the VSC light comes on! Wonder who the dim-witted engineer was that designed that. My VSC lights and check engine lights came on and my SR5 was running a little rough. Looked on the forums and reset the gas cap to get lights to go off.
When do the VSC off and check engine lights come on?
“VSC Off” and “VSC TRAC” lights will often come on when an error code triggers the Check Engine light. It doesn’t necessarily mean there is an issue with those systems. If they all showed up at the same time, it’s likely that diagnosing the cause for the Check Engine light will fix them all.
What kind of TRAC system does Toyota Sequoia have?
It just happened to me in my 2006 Toyota Sequoia v8 4.7 2wd. One morning, the Check Engine light come on, also the “RSA” and Track Off” and they didn’t go away. I check the code and a P1010 was there, a MASF sensor. I clean it and the lights, including RSA and Track Of went off.
