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
- Dirty throttle body
- Clogged air filter or intake duct
- In winter — ice on the throttle plate
- MAF or MAP sensor
What you can do yourself
- Clean the carbon off the throttle body and check the connector.
- After cleaning or replacing, run a throttle relearn (adaptation).
- The car may go into limp mode: weak pull, revs won’t rise.
- If the car stops responding to the gas pedal completely while driving, turn on the hazard lights, pull over to the shoulder and stop. If it still drives but responds poorly, you can drive on carefully, but don’t put off the check.
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.
