P0500 CHEVROLET - Vehicle Speed Sensor Circuit
Faulty Vehicle Speed Sensor
Vehicle speed sensor harness or connectors is open or shorted
Vehicle speed sensor circuit poor electrical connection
Faulty Powertrain Control Module (PCM)
When is the code detected?
The almost 0 km/h (0 MPH) signal from vehicle speed sensor is sent to Powertrain Control Module (PCM) even when vehicle is being driven.
Engine Light ON (or Service Engine Soon Warning Light)
Speedometer may not work properly
Transmission shifting problem
P0500 Chevrolet Description
A toothed wheel mounted on the output shaft of the transmission generates an AC voltage pulse as it moves past the Vehicle Speed Sensor (VSS). The VSS contains a permanent magnet surrounded by a coil of wire, which produces a magnetic field. The toothed wheel interrupts the magnetic field this generates an AC voltage pulse. As the vehicle speed increases the AC voltage pulse rate also increases. The Powertrain Control Module (PCM
) determines the vehicle speed based on the frequency of these pulse signals.
