This is the third time this has happened, i've been driving and i suddenly lose all of my throttle and the check engine comes on. The other times this has happened the battery light came on too, so i replaced the battery in hopes that that'd be the end of it, but today the same thing occured. Also other times the check engine light would just randomly go out. Scanned the car and the two codes (i believe dtc) that came up are 833 which had no info and 532, which said voltage supply signal too low.
