1. Clogged EGR system
2. Blocked exhaust system
3. Restricted pressure sensor before turbine tube
4. Pressure sensor before turbine deviation
5. Air leakage between intercooler and inlet manifold
ADDITIONAL INFORMATION:
1. The measured pressure before turbine is compared with an expected pressure before turbine.
2. The pressure before turbine is measured by the pressure sensor before turbine (F826).
