DTC P0500 VEHICLE SPEED SENSOR (VSS) MALFUNCTION





WIRING DIAGRAM

CIRCUIT DESCRIPTION
The vehicle speed sensor, located on the transmission, generates a signal in proportion to the vehicle speed (Signal 1). Receiving this signal, the speedometer uses it for operation of its indicator and also converts it into the ON/OFF signal by doubling the cycle (Signal 2). This signal is sent to ECM where it is used as one of the signals to control various devices.
