P2564 - TURBOCHARGER BOOST CONTROL POSITION SENSOR "A" CIRCUIT LOW

The Turbocharger Boost Control Position Sensor (TBCPS) allows the PowertrainControl module (PCM) to make adjustments to the amount of boost delivered to the turbocharger during vehicle operation. In this process, if the PCM adjusts the pulses like the manufacturer, fuel delivery and ignition timing will be efficient.

In case the PCM detects that the Turbocharger Control Position Sensor voltage supply wire has a voltage level below 0.3 volts according to the manufacturer’s set parameters, the diagnostic code P2564 OBDII will be stored.

• Check Engine light illumination.
• The engine has acceleration problems.
• Low fuel economy efficiency.
• Engine performance problems.

The DTC P2564 OBD2 is set for the following reasons:

• Turbocharger Control Position Sensor wires possibly have damage causing the low voltages.
• The turbocharger may work wrongly due to excessive soot buildup.
• Turbocharger Boost Control Position Sensor may be faulty.

To troubleshoot the P2564 OBDII fault code, follow these steps:

• Consult the Technical Service Bulletins (TSB).
• Verify that the TBCPS connector is tightened properly and that its pins are not bent. If you notice any irregularities, fix them if necessary
• Check that the wiring associated with the Turbocharger Boost Control Position Sensor circuit is in good condition. If these components are faulty due to exposure to a high temperature, make repairs if necessary.
• Check the sensor for soot buildup that could affect the sensor's performance. It is recommended that you refer to the service manuals for maintenance.
• Use a multimeter to perform resistance checks on the Turbocharger Control Position Sensor. If the result of this test shows a value out of range of the programmed values, replace the sensor.
