Vehicle Speed - Wheel Speed Correlation
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.
Affected components
- Vehicle speed sensor
- Wheel speed sensor
Common causes
- High likelihood: Tyre size mismatch versus calibration
- Medium likelihood: One sensor drifts or fails
Diagnostic notes
- The malfunction indicator lamp may illuminate
- This code can affect emissions
