Pontiac Vibe: VSS – Circuit Malfunction
P0500 OBDII Trouble Code that can affect the Pontiac Vibe‘s Vehicle Speed Sensor (VSS). The VSS sends a signal to the engine’s computer letting it know how fast that the vehicle is going.
For many vehicle functions, the Vibe utilizes this signal. It controls the transmission shifts, ABS and cruise control. Repairing this should be a top priority.
Pontiac Vibe P0500 Signs
The model year as well as other factors can affect the symptoms. However, these are the most prevalent symptoms of P0500.
- Failed speedometer– Without a properly working vehicles speed sensor, the speedometer will not register any speed. It’ll just sit at 0 MPH while you are driving. It's the Odometer It may not be possible.
- Cruise Control failure– When a vehicle is not getting a signal from the VSS, it’ll not let the cruise control engage. This makes sense since it can’t control the speed when it doesn’t know how fast it is going.
- Harsh Shifts It is possible for the transmission to shift in a different way than usual.
- Anti-Lock Brakes– The Vibe’s ABS may not work or could be compromised. VSS is one part of a more complex set of sensors which prevents the wheels locking under high break pressure.

- Bad VSS– More often than not, when P0500 is thrown, replacing the Vehicle Speed Sensor will remedy the problem. These sensors are It's also quite affordable.
