Diagnostic Trouble Code (DTC) P0500
DTC Description
Note : The symptom byte may not be displayed on a scan tool.
DTC P0500 (08): Vehicle Speed Sensor (VSS) Circuit (Signal Invalid)
DTC P0500 (11): Vehicle Speed Sensor (VSS) Circuit (Above Maximum Threshold)
DTC P0500 (71): Vehicle Speed Sensor (VSS) Circuit (Invalid Serial Data Received)
Circuit/System Description
Vehicle speed information is provided to the engine control module (ECM) by the vehicle speed sensor (VSS) that produces a pulsing voltage. The A/C voltage level and the number of pulses increase with vehicle speed. The converted signal is supplied to the instrument panel for speedometer/ odometer operation and to the cruise control module, etc. The diagnostic trouble code (DTC) will detect whether the serial data line is functional and the VSS is sending reliable vehicle speed data.
Conditions for Running the DTC
Conditions for Setting the DTC
P0500(08)
- The ECM detects that the vehicle speed is less than 1km/h
P0500(11)
- The ECM detects that the vehicle speed is greater than 300km/h

Diagnostic Aids
- For an intermittent fault condition, refer to "Intermittent Conditions".
- Inspect the sensor for an incorrectly routed harness or if the harness is too close to the following:
