P215A — 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.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
Affected components
- Vehicle speed sensor
- Wheel speed sensor
Possible causes to check
These are possible checks, not a ranked diagnosis. Follow the vehicle manufacturer's test procedure before replacing parts.
- Tyre size mismatch versus calibration
- One sensor drifts or fails
Diagnostic notes
- The malfunction indicator lamp may illuminate
- This code can affect emissions

Check each reference's vehicle and model-year scope. General background links do not establish which fault is most likely on your vehicle.
Diagnostic information is provided for reference only. Confirm the code with a compatible scan tool and follow the vehicle manufacturer's service procedures before replacing components.
