P2563 OBD-II Trouble Code: Turbocharger Boost Control Position Sensor Circuit Range/Performance

Check Engine Light

P2563 code definition

Turbocharger Boost Control Position Sensor Circuit Range/Performance

What the P2563 code means

P2563 is an OBD-II generic code. The engine control module (ECM) monitors the variable geometry turbocharger electronic actuator. This code indicates that the ECM has detected a problem with the variable vane geometry turbo control. Either the position sensor is not within specifications or the performance is out of range while being monitored.

What causes the P2563 code?

  • The turbocharger actuator has electronic sensors that monitor turbo vane position and will send feedback signals on the controller area network (CAN) bus to the ECM for turbo vane position and amount of turbo boost.

  • A turbocharger electronic actuator boost sensor is defective.

  • A bad turbocharger or the vanes are binding in the wrong position.

  • Soot build up on vanes not letting vane go back to normal position at startup.

What are the symptoms of the P2563 code?

  • The Check Engine Light will be illuminated and the code P2563 is set in ECM memory as a fault.

  • The engine will have low or no turbo boost and lack power on acceleration or under load.

  • The ECM may go into failure management mode causing the engine to have reduced power.

How does a mechanic diagnose the P2563 code?

  • Scans codes and documents the code in the ECM and looks at the freeze frame data for failure

  • Runs a soot clean of the turbo and exhaust system then clears codes and retests

  • Measures the resistance of the actuator following a pinpoint test for specification

  • Checks the harness for short or broken wires

  • Follows the manufacturer pinpoint testing for further diagnostics of the turbocharger

Common mistakes when diagnosing the P2563 code?

  • Not addressing code P2563 before other codes. This code may cause the other codes related to the turbo.

  • Failing to clear the ECM codes after the codes are fixed and retesting to verify the fix

How serious is the P2563 code?

  • Code P2563 is for the turbocharger boost sensor indicating the vanes are in the incorrect position when the ECM monitors the position at startup of the engine. The buildup of soot can cause the vanes to not move good and bind.

What repairs can fix the P2563 code

  • Performing a soot cleaning of the turbo control system
  • Replacing the turbocharger control actuator assembly
  • Replacing the turbocharger assembly
  • Repairing or replacing a wire harness or connection to the control actuator

Additional comments for consideration regarding the P2563 code

Code P2563 may indicate the turbocharger has excessive amounts of soot built up on the variable turbo vanes. If cleaning soot out twice does not clear the codes, then the turbocharger would need to be replaced.
