Sometimes is will, sometimes it won't! There are often times where is can be the idle air control motor as well, sometimes it won't set the CEL either. It is best to go to a place where they can check the fuel trims on the scan tool. You would have one rare Lexus if the fuel pump is bad. If one of the coil packs are bad, it would not only set the check engine light, it would flash. It is possible that the VVT-i sensors are bad in the engine as well.
