P0272
Cylinder 4 Contribution/Balance Fault
Moderate severity
What it means
The ECU compares each cylinder's contribution to crankshaft speed (rough run analysis) and determined cylinder 4 contributes less or more than the average. This points to a mechanical or fuel delivery problem rather than a pure ignition fault.
