A turbocharger is an air pump that increases the pressure inside the intake manifold, supplying more air into the combustion chamber for more engine power. A wastegate and corresponding actuator are typically used to control turbocharger boost pressure. In some cases, a sensor is used to measure the position of the wastegate. If the PCM detects a problem with the sensor, on-board diagnostics (OBD) will log a P2565 code.
What Does the P2565 Code Mean?
Diagnostic trouble code (DTC) P2565 stands for “Turbocharger Boost Control Position Sensor ‘A’ Circuit High.”
The PCM uses a turbo boost control position sensor to measure the position of the wastegate. In some cases, a variable geometry turbocharger (VGT) is used instead. As the vanes and potentiometer move inside the VGT, the voltage signal supplied to the PCM changes.
If the PCM detects an unusual signal from the turbocharger boost position sensor, a P2565 code will be set.
Note: The definition of code P2565 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
What are the Common Causes of the P2565 Code?
- Turbocharger boost control position sensor failure
- An issue with the wastegate actuator rod
- Failed wastegate actuator
- Bad turbocharger
- Wiring issues
- PCM failure
What are the Common Symptoms of the P2565 Code?
- Illuminated check engine light
- Poor turbocharger performance
- Hesitation upon acceleration
- Poor fuel economy
How to Diagnose the P2565 Code
DTC P2565 is a manufacturer-specific powertrain code that can be logged in turbocharged vehicles with an OBD-II system. Diagnosing this type of code might require you to use a scan tool and conduct visual inspections, which might be confusing for someone who’s not well-versed in automotive repair. If this is the case for you, it might be best to have a certified professional diagnose your vehicle instead.
But if you’ve had your fair share of diagnosing trouble codes before, here’s something you might want to look at before you begin.
How to Fix the P2565 Code
Attempting to fix a P2565 trouble code without the right tools and technical knowledge can be tricky and can even lead to further complications down the road. Under these circumstances, it’s best to bring your vehicle to a reliable auto repair shop to resolve the issue. This will ensure that all steps and protocols are followed correctly.
But if you think you can handle the task on your own, make sure you have the right equipment and information before proceeding. By now, you already know that there’s no such thing as a magic bullet that will resolve all codes for all makes and models. So before you begin, you might want to check out guides like those from Chilton or an ALLDATA subscription for vehicle-specific repair information.
