P0500 on Volvo
Vehicle Speed Sensor Malfunction
P0500 on Volvo vehicles indicates vehicle speed sensor malfunction. Au7o has documented this code across 1 Volvo model — most commonly on 850. 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. Typical repair costs on Volvo range from $50 to $300, depending on the specific model and root cause.
Common Causes of P0500
- •Failed vehicle speed sensor
- •Corroded or loose speed sensor connector
- •Damaged, open, or shorted sensor wiring
- •Damaged sensor tone/reluctor ring
- •Faulty ABS wheel speed sensor (on systems that derive speed from ABS)
- •Poor sensor power or ground
- •Blown fuse in the sensor circuit
- •Faulty PCM/ECM or instrument cluster (rare)

- Speedometer and Odometer Intermittent Failure1993-1997
The instrument cluster on the Volvo 850 is prone to intermittent speedometer and odometer failure caused by deteriorating solder joints on the circuit board, particularly on the vehicle speed signal circuit. The speedometer may bounce, read incorrectly, or drop to zero while driving. Since the ECU uses vehicle speed data for shift points and idle control, this can also cause rough shifting and erratic idle.

What does P0500 mean on Volvo?▼
P0500 stands for "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. On Volvo specifically, this code is documented across 1 model.
