About P2562

P2562 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P2562 is stored, the module has detected a sensor-related fault — the reported value from the named sensor is out of spec.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P2562 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

P2562 is a generic powertrain code that sets when the ECM sees an implausible, out of range or missing signal from turbocharger boost control position sensor A. On a variable geometry turbocharger this sensor sits inside the electronic vane actuator and reports actual vane position back to the ECM, which compares it against the commanded position so boost control can run closed loop. On a wastegate equipped turbocharger the same sensor reports wastegate rod or actuator position instead. The code stores when the reported position fails to track the command within the allowed tolerance, or when ...
