Newer cars use what is referred to as "Drive by Wire. Instead of a throttle cable that goes to the throttle body, there is a sensor on the gas pedal and another on the throttle body. The signal from the pedal is sent to the ECM, analyzed, and transmitted to the throttle body to perform the desired operation. If something in that chain breaks down, the car is disabled as a safety feature, so that you wouldn't have, say, a wide open throttle issue to deal with. That is what the "starting disabled, service throttle" means. As far as the oil light and low oil pressure indications, if the key is on, and the engine is not running, these are normal indications since there is no oil pressure in the engine when it is not running.
I put a new throttle body on the impala and the code was p0641 the people at Oreilly's didn even know what that code is and do I need to change the sensor at the gas pedal
You can check it. Sometimes they only need to be cleaned as they get filthy being down on the floor. I have found other information regarding two GM tech service bulletins regarding the P0641 code. Apparently they have had some issues with chafed wiring harnesses in certain locations causing this issue. I am linking you to a Impala forum article where it is discussed and there are photos that will show you where to investigate for wiring issues.

SOURCE: like 3 days after i got my oil changed in my 2006
This is an idication of a severe oil leak. Check the oil level in your engine to see if there is any in it. Add to the full mark and return to the oil change shop and ask them to see where the leak is. Do not operate without oil. Severe engine damage will occur. Hope this helps Moe
SOURCE: OIL PRESSUE LOW
At some point, your engine is registering low oil pressure and warning you the oil pressure is insufficient to lubricate the engine properly.
How does the engine know this? What causes it? Excellent questions. The engine 'knows' this because there is one or more sensors that read the oil pressure all the time. The sensors report to the computer which reports to you. They could be faulty. On the other hand, there could be times when oil pressure IS low. Your oil pump may be mal-functioning. Normally, I would expect the oil pump to either do its job properly or NOT do it properly but not act intermittently. It may warrant being checked by a professional. Another reason for this condition could be the oil itself, though you report you just had it changed. Presumably, whom ever did the change put in the proper oil grade, service and weight, recommended by GM.
Another thought, is this warning seen by you immediately after you start the car? If yes, it is normal for oil to take a second or two to build the proper pressure, particularly in cold weather. Where I am at, it is cold. Oil doesn't like to move when it is cold (like me) so it takes a bit of time to get up pressure (like me).
If this continues, you may want to have this problem looked at by a professional, as I said.

SOURCE: I have a 2006 Impala 118844 miles. engine power
Your fuel pump power is controlled through the oil pressure switch, and if it is showing low pressure due to a leaking/defective oil pressure switch, it may shut off the fuel pump. Oil pressure switch failures are a common source for oil leaks. There could, and probably are, other issues going on. You never mentioned if the "check engine" light was on, and if it is, a scan would definitely be in order to determine the true cause of your problem
If it is not on, GM fuel pump failures are very common, as well as the vehicle security system my be having a programming issue. I would start by having the engine scanned (most Autozone locations do this for no charge) Good luck!
Check
engine light comes on and off, these are indication that there is some
error code stored in your vehicles ECM. The engine module computer
needs to be scanned. These will give the code and as per the error code the
further problem can be detected and confirmed. The engine light
indicator blinks or remains steady on dash when engine computer
noticed any problem with any engine electrically operated components.
For
more help, I suggest you to refer the help links provided below. These will let
you know more about which areas to look, check, when there is engine light
coming up on dash panel.
