OBD Diagnostics for Fuel Injector Balance and Efficiency

Fuel injectors must deliver equal fuel to each cylinder. OBD injector balance diagnostics help identify injectors that are underperforming or clogged.

How Injector Imbalance Affects Engines

Uneven Power Output

Imbalanced injectors cause vibration and rough running.

Increased Emissions

Poor atomization leads to incomplete combustion.

OBD Data Used for Injector Analysis

Key Indicators

• Fuel trims per bank

• Misfire counters

• RPM fluctuation

Benefits of Injector Balance Diagnostics

• Smoother engine performance

• Better fuel economy

• Reduced emissions

Conclusion

OBD diagnostics ensure injectors work evenly for optimal combustion.
