Troubleshooting

Stuck fuel rack? Starting air valve leakage? Malfunctioning fuel valves or sensors?
If your engine is underperforming or experiencing unexplained faults, you are in need of YAF Engineering’s expert diesel engine troubleshooting services.

  • Onboard fault diagnosis and system performance evaluation
  • Sensor calibration and alarm functionality testing
  • Fuel and air system inspections
  • Mechanical and electrical component assessments
  • In-situ corrective actions to restore engine reliability

By combining hands-on engineering experience with in-depth system knowledge, we ensure your engine returns to full operation safely, efficiently, and with minimal downtime.
