Chevy Aveo: VSS – Circuit Malfunction
P0500 This OBDII code is used to troubleshoot the Chevy Aveo‘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.
This signal is used by the Aveo for many functions. It controls the transmission shifts, ABS and cruise control. It should be fixed as soon as possible.
Chevy Aveo P0500 Symptoms
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 Another reason is that it may not work.
- Cruise Control Failed– 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 You might notice a shift that is different from what you are used to.
- Anti-Lock Brakes– The Aveo’s ABS may not work or could be compromised. VSS is just one of many sensors in a complex system that prevents the wheels from locking when there's heavy breaking pressure.
Chevy Aveo - P0500 Causes
- Bad VSS– More often than not, when P0500 is thrown, replacing the Vehicle Speed Sensor will remedy the problem. They're It's also quite affordable.
- The Wiring Problem– Due to the location of the VSS, the wiring harness going from the vehicles computer to it can often become damaged and open/short out. The Aveo may not be able tell what the VSS reads if this occurs. You can look at the harness from a safe distance. It should be plugged in every step. Check to see if the wiring has become frayed. Here’s How to Check for a Short (YouTube).
- Tires– On some vehicles, P0500 can be thrown if the tires have been swapped to a size that is different from the factory setting.
These P0500 reasons will be why the code was thrown the majority of the times. The ECM/PCM could be bad. It is important to not look at the first place, but instead the second.
Because of their location, it is possible for the wiring harness connecting to them to fail. It is a bad idea to replace it without checking it.
Fixed Price: P0500
You should inspect the Wiring Harness first. If everything looks fine, you can then inspect the VSS. Is there any visible damage to the VSS?
After you do that, (or before, if necessary), Good scan tool) it’s time to test the sensor and see if the VSS signal goes up and down with the vehicle speed. If it doesn’t, replacing the sensor could fix the problem. If it does, you’ll have to test the rest of the circuit.
It can be difficult to diagnose P0500 problems in the Chevy Aveo. Don’t skip checking the wiring harness first. Have fun!
