You should get another check engine code. It may be the throttle body or another sensor like the TPS throttle positioning sensor

Wow I know that me and three other people I know have recently gotten that same code!!! What in the heck??! My car would literally jerk and shake when I tried to accelerate,, needless to say none of what their codes said helped it and now it's in it's grave, rusting, so sad. It is strange those codes just come up with everyone
