Problems with my corsa city

Hello guys, in April my dad bought me a Corsa City 1.0 of the year 98 ', and I was learning to handle, so when I had been with the car for two months, I started giving problems. Derrepente was driving and the engine went out ... after a few minutes I made it walk and ran again. This began to spend more followed ... and the waiting times were increasingly long. He took him to make him a scanner, and I got out that they had disconnected the Check Engin, so every time he stopped I did not turn on any light. Now I fix that light ... and when you stop ... but it is already a problem and I don't know what to do with it. I leave my house doi a return to the roundabout and stop and I have to wait like an hour to walk just a few more blocks and stop again.
I do not understand mechanics, but it has happened to help.
These are the codes that came out in the first scanner.
- Po 650: *Active check Engine
*Light Circuit Open Open

- PO335: History (CKP Sensor CUANIAL POSITION)
RPM NON -SIGNAL SENSOR

- PO 100: HISTORY
MASS AIR FLOW VOLTAGE LOW SENSOR SENSOR VOLTAGE LOW

now I will do the second scanner and there you will see ... I hope I don't get expensive.

Hello in the Corsa City 1.0, a problem has been discovered that may have to do with your fault the canister that is a deposit to which the vapors of the fuel pond are located is located in a very low position with respect to the pond and sometimes it is filled with fuel instead of vapors and this fuel is aspirated to the engine causing the engine to drown In a higher position it is not difficult, who should only extend any hose, I could help you there.

Good, according to the codes that you indicate, it is surely the CKP sensor must have the internally burst cables, it passes a lot with these sensors due to the type of signal they handle, test with another, the mechanic that serves you must have one for tests, I hope I have helped you,

Finally take it to the mechanic and after making another scanner, I got out that it was the crankshaft position sensor, also known as CPK.
Buy the alternative ... that it was very cheap, if the workforce cost me the most. After changing the car has not given me problems. Now I have to change the coil that is all patched and ugly. But I have to quote it. (I think it's very expensive)
Thank you for help !!!
