Speedometer not working or reading incorrectly

Needs attention soon

speedometer stuck at zero · speedometer needle jumps around

Symptom description

The speedometer reads zero regardless of actual speed, jumps erratically, or shows an obviously incorrect speed.

Common causes

  • A failed vehicle speed sensor
  • A wiring fault between the sensor and the instrument cluster
  • A fault within the instrument cluster itself

What to check

Note whether the odometer and cruise control are also affected - they often share the same speed sensor, and a pattern helps confirm the cause.

Can you keep driving?

Drive cautiously and rely on posted speed limits and traffic flow. Get it fixed soon, since it also often disables cruise control and can trigger other systems relying on speed data.
