The sensor for vehicle_speed is reporting 0-250km/h

OBD2 PID for Vehicle Speed:

The PID for vehicle speed is 0x0D.
Formula for Calculating Vehicle Speed:

• The response for PID 0x0D is a single byte (A).
• The formula to convert this byte (A) into vehicle speed is:
• Vehicle Speed (km/h)=A

How to Use the Data:
When you request PID 0x0D, you will get a value for A in hexadecimal.
Convert the hexadecimal value of A to decimal, and that is the vehicle speed in kilometers per hour (km/h).

Example:
Let’s say the OBD2 scanner reads a value of 0x28 for PID 0x0D.
Convert 0x28 to decimal:
0x28=40 (decimal)
This means the vehicle speed is:
Vehicle Speed=40km/h
