Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
DTC P0500: Vehicle Speed Sensor (M/T): Description
The Vehicle Speed Sensor (VSS) assembly provides vehicle speed information to the Powertrain Control Module (PCM). The VSS assembly is a permanent magnet generator. The VSS produces alternating current (AC) as the rotor teeth on the output shaft of the transmission (2WD) or transfer case (4WD) pass through the sensor's magnetic field. The frequency and amplitude of the AC waveform both increase as vehicle speed increases. If the PCM detects no vehicle speed for a specified length of time while other sensors indicate that the vehicle is moving, DTC P0500 sets.
