Troubleshooting and Problem Solving

Common Issues After Installation

• Check Engine Light: Usually caused by incomplete vehicle system reset after modification.
• Slight Turbo Lag: Normal adaptive state of turbo system during initial running-in period.
• Minor Idle Fluctuation: Caused by engine self-learning and fuel injection adjustment process.
• Gasket Air Leakage: Result of uneven bolt tightening or misaligned gasket installation.
• Excessive Smoke Residue: Remaining carbon deposits in original exhaust pipeline, normal early state.

Error Code Solutions

• P0401: EGR Flow Insufficient - Reset vehicle ECU and clear residual system fault data.
• P0402: Excessive EGR Flow - Check blind plate installation tightness and gasket sealing status.
• P0403: EGR Control Circuit Malfunction - Reconnect wiring and complete system reset.
• P0171: System Too Lean - Run road test to complete engine self-learning adaptation.

How to Reset Check Engine Light After Installation

1. Turn off the vehicle engine and disconnect the battery negative terminal for 5-10 minutes.
2. Reconnect the battery and start the engine to idle steadily for 10 minutes.
3. Drive the vehicle steadily for 5-10 miles to finish engine system self-adaptation.
4. Use an OBD scanner to clear remaining fault codes and complete reset operation.

What to Do If Your Vehicle Loses Power After Installation

• Verify blind plate and gasket are installed correctly without deviation or air leakage.
• Check all exhaust pipeline connections for blockage or poor ventilation issues.
• Complete full ECU reset and perform road test to adapt engine operating parameters.
• Confirm no loose fasteners affecting engine air intake and exhaust efficiency.

Long-Term Maintenance Tips

• Sealing Inspection: Every 5000 miles check gasket and blind plate for air leakage or looseness.
• Exhaust Pipeline Cleaning: Every 10000 miles clean exhaust passages to remove residual carbon deposits.
• Gasket Replacement: Replace high-temperature gasket every 30000 miles to maintain sealing performance.
• Fastener Tightening: Every 15000 miles retighten bolts to prevent vibration-induced looseness.
• Component Check: Inspect plate deformation and corrosion regularly to ensure long-term stability.
• Warranty Compliance: Follow all maintenance guidelines to keep 1-year warranty fully valid.
