What's the 2002 dodge ram 1500 code p0500?

When the 2002 Dodge Ram 1500 returns a P0500 trouble code, it means a problem with the vehicle speed sensor (VSS) has been identified. Although it sounds serious, and it can greatly affect performance, it's actually a fairly inexpensive repair on this truck. Replacing the VSS on this vehicle generally costs between $120 and $140. Labor accounts for about $30 to $50 of that total, so You can save a bit of money, if You handle the repair Yourself. The VSS is responsible for sending signals to the computer in the engine to let it know how fast the vehicle is going. It essentially helps to control cruise control, speedometer, ABS, and transmission shifts. Aside from a check engine light being on and a trouble code being returned, additional symptoms of a bad VSS include cruise control not working and incorrect shifting of gears.
