P0500 is an OBD-II diagnostic trouble code meaning “Vehicle Speed Sensor Malfunction.” This code indicates the vehicle speed sensor (VSS) signal is missing, erratic, or out of range. The speed sensor reports how fast the vehicle is moving, and the computer uses that input for the speedometer, transmission shift timing, cruise control, ABS coordination, and other functions. When the expected speed signal isn't present or doesn't match other data, P0500 sets. Symptoms can include an inoperative or erratic speedometer, harsh or delayed shifts, and cruise control that won't engage. This code is most commonly reported on 1988-1995 Chevrolet C/K 1500, and 1993-1997 Volvo 850, with repair costs ranging from $20 to $300.
