P0500 means the engine control unit is not receiving a valid signal from the vehicle speed sensor. This sensor, typically mounted on the transmission or wheel hub, tells the ECU how fast the vehicle is moving. Without it, the speedometer, cruise control, ABS, and transmission shift logic are affected.

P0500 is a electrical-related diagnostic trouble code classified as moderate severity. When your vehicle's ECU detects this condition, it stores P0500 and illuminates the check engine light.
If your vehicle has triggered P0500, you may notice one or more of these symptoms:
Here are the most common causes of P0500, ranked by how likely they are to be the culprit:
No - address this immediately. Without a valid speed signal, the speedometer will not work, ABS and traction control may be disabled, and automatic transmission shift points will be incorrect. Drive cautiously to a repair facility.
Follow these steps to pinpoint the root cause of P0500:
Repair costs for P0500 vary depending on the root cause and your vehicle. Here are typical estimates:
Prices estimated as of March 2026. Costs vary by region, vehicle, and shop.

These codes are often seen alongside P0500 or indicate related issues:
You can physically drive the vehicle, but the speedometer will not work, making it illegal to drive on public roads in most EU countries. ABS and traction control will also be disabled, reducing safety. Drive cautiously to the nearest workshop.
On most vehicles, the primary speed sensor is mounted on the transmission housing, either on the output shaft or the differential. Some newer vehicles use wheel speed sensors (ABS sensors) as the primary speed input to the ECU.
Yes. Automatic transmissions rely on the vehicle speed sensor to determine when to shift gears. Without a valid signal, the transmission may shift late, shift harshly, or stay locked in one gear (limp mode) to protect itself.
Yes. The ABS system requires accurate speed data from all wheels and the vehicle speed sensor. If the ECU cannot determine vehicle speed, it disables ABS and traction control as a safety precaution and illuminates the warning lights.
The sensor itself is typically 15 to 80 EUR. Labour ranges from 40 to 150 EUR depending on accessibility. On most vehicles, the sensor is held in by a single bolt and can be replaced in under an hour.
