OBD Diagnostics for Engine Power Balance and Cylinder Efficiency

An engine runs best when all cylinders produce equal power. OBD power balance diagnostics help identify cylinders that contribute less power than others.

What Is Engine Power Balance?

Why Balance Matters

Uneven power causes:

• Rough running

• Increased vibration

• Higher emissions

How OBD Evaluates Cylinder Performance

Key Indicators

• Misfire counters

• RPM fluctuation analysis

• Fuel trim variations

Common Causes of Imbalance

• Weak ignition

• Fuel injector issues

• Compression loss

Benefits of Power Balance Diagnostics

• Smooth engine operation

• Improved fuel economy

• Reduced emissions

• Accurate cylinder-specific repairs

Conclusion

OBD power balance diagnostics ensure every cylinder contributes equally to performance.
