DTC P0500: Vehicle Speed Sensor (VSS) Circuit Malfunction (M/T Model)

General Description
The vehicle speed sensor (VSS) is attached to the transmission housing. The VSS outputs a pulsing signal for every revolution of the differential gear via the speedometer gear. The engine control module (ECM) determines the vehicle speed based on the frequency of these signals. If there is a loss of VSS signals to the ECM, the ECM detects a malfunction. If an open, a temporary open, or a short to ground causes a malfunction, a DTC is stored.
