P0500 is a diagnostic trouble code (DTC) for "Vehicle Speed Sensor Malfunction". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
P0500 is a general OBD-II code that indicates a malfunction has been detected in the vehicle speed sensor circuit. This code may be seen with P0501, P0502, and P0503.
The P0500 diagnostic trouble code tells us there is a fault found with the vehicle speed sensor. The speed sensor is monitored by the ECU and when it fails to operate properly the P0500 code is set. Once the code is set, the Check Engine Light will illuminate on the dashboard.
P0500 has a few standard causes:
Qualified technicians hook up a scan tool to the vehicle to check for any codes present and will note all codes found along with the freeze frame data.
All codes will be cleared to start with a fresh look at the vehicle. Next, a road test will be performed to confirm the problem is present.
The technician will then visually check the speed sensor and all associated wiring for obvious damage or wear.
Next, the scan tool will be used to check if a vehicle speed sensor (VSS) signal is present at all when driving.
Lastly, the voltage will be checked using a multimeter at the vehicle speed sensor.
If diagnosis is not performed, the vehicle’s speedometer may be replaced due to it not working only for the vehicle speed sensor to be the cause. Proper diagnosis tests all components on a step-by-step basis to avoid unnecessary repairs.
P0500 will not prevent the vehicle from operating but it may shift roughly causing some discomfort when driving. If the speedometer is not working, care must be taken to drive within the speed limits until the vehicle is repaired. If the ABS system and Traction Control System (TCS) do not operate, care should be taken when driving especially during adverse weather conditions.
Depending on the year and drive type of the vehicle, the location of the vehicle speed sensor can vary greatly. On front wheel drive cars the speed sensor is often found on the front wheel hub. On rear wheel drive vehicles the speed sensor may be found on the output shaft of the transmission or located within the rear differential. More modern vehicles may have a speed sensor located on each wheel.
The ECU uses the information from the vehicle speed sensor to display the proper speed on the speedometer. In addition, this information is used to tell the transmission when to shift and monitors other safety features, such as the anti-lock brakes and traction control system.
