The Turbo Compressor Control Position Sensor (TBCPS) is in charge of converting the turbo compressor pressures into electrical signals sent to the Powertrain Control Module (PCM). This information is used to control the proper amount of fuel delivery, ignition timing strategy, and the pulses provided to the engine by the turbocharger.
When the PCM detects signals in the Turbo Boost Control Position Sensor electrical circuit that are outside the levels set by the manufacturer, the DTC P2563 OBDII code will be stored. It is important to note that this type of code is rarely triggered by turbocharger failures.
