Cylinder 11 Above Knock/Combustion Vibration Sensor Threshold
What it means
The knock or combustion-vibration sensor monitors the structure-borne noise of each cylinder. The signal level for cylinder 11 has stayed above the diagnostic threshold for an extended period, indicating either persistent knock or an electrical fault that biases the channel high.
Is it safe to drive?
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
