009571/P2563 - Turbocharger Boost Control Position Sensor Circuit: Implausible Signal

This fault code may be caused when the Actual and Specified Turbocharger requests are considered Implausible by the engine controller.

Possible Symptoms

• MIL on

Possible Causes

• Wiring and/or connections faulty
• ECM faulty
• G581 (Vane Position Sensor) Faulty or Binding due to adjustment/Turbocharger issues
• Vacuum leak to/from Turbocharger (wastegate) actuator and Solenoid Valve for Boost Pressure Control (N75)

Possible Solutions

• Check fuses
• Check wiring and connections
• Ohm test G581, see factory repair manual
• Check mechanical Turbocharger operation to rule out binging and excessive carbon
• Check vacuum supply to/from Solenoid Valve for Boost Pressure Control (N75) and Turbocharger (wastegate) actuator

Special Notes

When this fault is found in the NAR Market 2.0L CR TDI:

• Measuring Block Group 034.2 (specified) and 034.3 (actual) G581 Vane Position Sensor values can be logged to see if the fields should mirror each other or deviate to confirm a problem.
• NAR market vehicles that had TPI 2025464 | TSB 21-11-01 -or- the latest TPI 2025464/5 | TSB 21-13-01 completed to prevent no-start conditions in cold weather caused by a frozen intercooler may want to see this thread.
