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
- Relearn not done after repair or replacement
- The relearn procedure was interrupted (for example, by a weak battery)
What you can do yourself
- Run the relearn (adaptation) with a scan tool per the manual
- Check the battery and terminals
- Diagnostics by a technician
Stop and don’t drive on if:
- The Check Engine light is flashing
- The temperature gauge is in the red or the overheating light is on
- The red oil pressure light is on
- Smoke from under the bonnet, a burning or petrol smell
- Strong jerking, knocking from the engine, or the car barely moves
The explanation comes from the error code reference in the AvtoElektrik PRO app.
