P2263

P2263-21 Turbocharger/Supercharger Boost System Performance- Signal amplitude < minimum

Possible Causes: Intake system blocked/leaking Manifold absolute pressure and temperature sensor fault Variable geometry turbine vane actuator fault Turbocharger failure

Action: Check the intake system for blockages/leaks, check for manifold absolute pressure and temperature sensor related DTCs and perform the relevant corrective actions Check the variable geometry turbine vane actuator linkage. Check the turbocharger bearing and oil seal. Install a new turbocharger as necessary
