DTC Advanced Diagnostics: P2564, P2565
DTC P2564:Turbocharger Wastegate Control Actuator Position Sensor Circuit Low Voltage
DTC P2565:Turbocharger Wastegate Control Actuator Position Sensor Circuit High Voltage

General Description

The powertrain control module (PCM) monitors the turbocharger wastegate control actuator position sensor circuit for electrical malfunctions. In order to provide electrical diagnostics, the output voltage of the turbocharger wastegate control actuator position sensor is continuously monitored and compared with minimum and maximum thresholds. If the turbocharger wastegate control actuator position sensor voltage is a specified value, the PCM detects a malfunction and stores a DTC.

Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
DTC: P2564
Turbocharger wastegate control actuator position sensor WGL line short to ground
Turbocharger wastegate control actuator position sensor VCC line open

DTC: P2565
Turbocharger wastegate control actuator position sensor WGL line short to power
Turbocharger wastegate control actuator position sensor WGL line open
Turbocharger wastegate control actuator position sensor SG line open

Common
Turbocharger wastegate control actuator position sensor failure
PCM internal circuit failure

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory.

Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command.
