I replaced the throttle body sensor and it got rid of my code 13 but it still flashed the 33. Since I suck at auto electronics, can someone explain to me how to approach this?

I don't know what tools to use to track this down. Any help would be greatly appreciated.

 

I think I'm done here, not gettin any help so think I'll go elsewhere.
