The B2623 is usually a bad dimmer switch is your dimmer switch bad?The code P1811 is usually a bad pressure control solenoid in the valve body I have replaced a ton of those pressure control solenoids for that code. Is the transmission shifting hard?The code P0621 the first step is to have the battery and alternator tested then go from there. The P1632 is theft deterent fuel disabled meaning the alarm was set off and the fuel was disabled. The P1780 means there is transmission codes and to tell the ecm to turn the check engine light on. The V2105 I have never heard of that code and dont see it in my online data. Recheck to see if it was different code.

Can you tell me if any of these codes would make the car lose power. The car just cuts off while driving. It is a used car and knew I would have to put money in it which one should be repaired first. I took the car to a saturn service shop and paid for testing I got all the codes I gave you from the saturn service shop after they worked on the car for three hours they still had no clue what was wrong they wanted another $200 just to find out what is wrong they said that it could be the computer but they are not sure but to change the computer was $800 and that might not be the problem so then I took it back where I got the car from they tried to put another computer on the car but the car would not start so what are my options Ido not have a lot of money to get things fixed and the car still doesnt work properly

The car jerks sometimes when the car loses power Mose of the time you dont even know that the car has cut off you look at the dash board and see the battery and oil light on

Iam a factory trained saturn tech was one for over 16yrs and I can tell you I have seen all those codes before there not uncommon. Except for that weird V code I dont know what thay that code is all about. The two codes I worry about first is the P0621 you need to have the alternator tested and the battery tested. Also make sure the battery cables are clean and tight. Thats where I would start with that code. Next I would work on the P1811 code I have seen that code left unfixed and the transmission destroys itself inside. So why did they say it needs a computer?When they replaced the computer was it a used one or new one?

Of course it wouldnt it wont start till you relearn the pass lock. If you replace the computer with a new or used computer you have to relearn the pass lock sensor. So why did they think it needs a computer?

Because the saturn repairman said that it could be the computer but they were not sure and did not want me to spend $800 replacing it and that did not solve the problem

Iam glad they didnt replace the computer because so far it doesnt look like a bad computer from the codes you have. Anything is possible but so far it doesnt look like a bad one. So they didnt diagnose any of the codes for the money they charged you just a guess you may have a bad computer?Then couldnt get it to start swaping it with a used computer?The code P0621 you will have to diagnose to figure out what it will take to fix it. But iam sure it will be cheaper then fixing code P1811 if its a bad pressure control solenoid your looking at 6-8hrs labor and couple hundred in parts. If you lived close enough to me I could help you out with lowering the cost of repair. But you probably dont even live in california.

No I live in Philadelphia, PA I wish I were closer because I would rather you work on my car. The saturn dealer told my husband that they couldnt find the problem and need an extra $200 to tell me exactly what is wrong, they gave me a print out with the codes that I gave you on it but no explanation of what the issues are. I looked on this wedsite to find out what the codes mean so I spent 110 for already and still dont know what is wrong. I thank you for all of your advice.I will get the P0621 code done first

Crank shaft the engine crank shaft?That would be a strange repair for the codes you have. Also your code P1811 is most likely going to be a pressure control solenoid in the transmision valve body.
