I have a 2011 Lexus es350, I get into an accident and the car was seating down for like 8month without driving, when I end up fixing it, I started have a slight problem the the throttle, my mechanic told me I need to change the throttle body which I did. And yet I still have the sane problem, now I was told to change the alternator. So I was trying to see if someone can give me an advice about it, because the car won't drive when I press the gas

 

Any codes?

 

It said cold p2118

 

this is what the code shows, and looks like your car is in failsafe mode

 

pls what idea do you have for me pls thanks

 

Do you have advanced diagnostic tools and skills? If not you should probably find a shop that does. I don't mean to overstate it, but this is going to need some more in depth diag work. Do not throw parts at it hoping for the best.
