17549/P1141/004417 - Load Calculation Cross Check: Implausible Value
- Mass Air Flow Sensor (G70) OR Manifold Pressure Sensor (G71) faulty
- Vacuum Lines faulty
- Check Mass Air Flow Sensor (G70) OR Manifold Pressure Sensor (G71)
- Check Vacuum Lines
- Check Engine Operating Conditions => Meas. Blocks
- Uwe: I think this code is set when the airflow being measured (or otherwise calculated) by the ECU doesn't make sense given other operating parameters such as RPM and throttle opening, manifold pressure, etc.
