Code P0500, where is the VSS located?

  • 4 CYL
  • 241,000 MILES
The code popped up P0500 is the VSS, and I would like to know where it's located. Can I fix it myself?
Do you
have the same problem?

The diagnostic trouble code (DTC) P0500 stands for "Vehicle Speed Sensor Malfunction." This code is triggered when the Engine Control Module (ECM) or another control module does not receive a signal from the vehicle speed sensor (VSS).

The vehicle speed sensor is a device that measures the speed at which the vehicle's driveshaft is rotating, which is then typically used by the engine control module to help control features like the fuel mixture, ignition timing, transmission shifting, and ABS braking.

When a P0500 code is stored, it indicates that the ECM has lost the signal from the VSS. This could be due to several issues, including:

A faulty vehicle speed sensor.
Damaged wires or connectors in the VSS circuit.
A faulty wheel speed sensor(s), as some systems derive vehicle speed information from these sensors.
A malfunction within the ECM itself (less common).
Symptoms of a P0500 code may include:

Check engine light is on.
Speedometer malfunction.
Odometer malfunction.
Cruise control malfunction.
Shift timing on automatic transmissions may be erratic.
Poor performance or decreased fuel economy.
ABS light is on.
To diagnose and fix the issue, a mechanic might perform the following steps:

Check the VSS and its wiring for signs of damage or disconnection.
Check the wheel speed sensors (if applicable) and their wiring.
Use a scanner to check the real-time output of the VSS while driving.
If no issues are found in these steps, further diagnosis of the ECM may be required.

Here is the location of the sensor. Check out the images (below). Please let us know if you need anything else to get the problem fixed.
