* Vehicle Speed Sensor (VSS): The VSS is located on the transmission and measures the speed of the output shaft. It sends this information to the powertrain control module (PCM), which uses it to control the transmission, speedometer, and cruise control.
* Wheel Speed Sensors: There are four wheel speed sensors, one at each wheel. These sensors measure the speed of each wheel and send this information to the ABS control module, which uses it to control the anti-lock brakes.
The speed sensors in a 2001 Chrysler 300M are essential for the safe and efficient operation of the vehicle. If you experience any problems with your speedometer, cruise control, or ABS, it is important to have the speed sensors checked.
