A fault code doesn’t yet mean the unit or sensor itself is faulty: often it’s the plug and connector leading to it.
Possible causes
- Speed exceeded the limit stored in the ECU
- Speed sensor or wheels of a different size
What you can do yourself
- The code is stored after driving faster than the limit. If you didn’t speed, check the speed sensor and the wheel size.
The explanation comes from the error code reference in the AvtoElektrik PRO app.
