P2563 is a diagnostic trouble code (DTC) for "Turbocharger Boost Control Position Sensor Circuit Range/Performance". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair.

Turbocharger Boost Control Position Sensor Circuit Range/Performance
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.
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.
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.
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
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
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.
