- Powertrain
- Manufacturer-specific

Diagnose soon
Usually safe to drive short distances, but the fault will not clear itself and can worsen or fail an emissions test.
Vehicle Speed - Wheel Speed Correlation
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
The vehicle speed signal computed from VSS does not match the wheel-speed signal from ABS within tolerance. One of the two sources is wrong, or there is a tyre-size mismatch.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.

| # | Cause | How often | Component |
|---|---|---|---|
| 1 | Tyre size mismatch versus calibration | Very common | — |
| 2 | One sensor drifts or fails | Common | — |
Ordering reflects how often each cause is responsible in general, not a probability for your vehicle. Confirm by testing.
