No.
no
yes you do because you need to know your speed limit
Yes
Need a new speedometer or speedometer cable.
Because the car is not moving
Not knowing the year, make and model vehicle it limits how much we can help you. If the speedometer cluster is digital and both the speedometer and odometer is not working I would suspect the vehicle speed sensor is at fault. If only the speedometer is not working I would suspect the dash cluster is at fault.
The problem would be that the car is messed up
What year, model, make is your car? it could be anything from the computer to the wire coming from your wheel.
Nope, bet it was the other way around... Your speedometer stopped working and your check engine light came on. A broken speedometer (don't know what car so I can't pinpoint it) will cause a whole bunch of codes.
it means the circuit of car is short........

Speedometer can determine a car's normal and maximum speed.
Well due to the velocity of that car it could either be pressure building up in that part or a certain liquid is building up/leaking and it is creating technical difficulties such the speedometer to stop working
