P2565 code definition

If you were to break down the meaning of each part of the P2565 OBD-II trouble code, it would yield something like “B” Rocker Arm Actuator Control Circuit Open Bank 1. For the average person, that definition doesn’t hold much meaning. When this fault code registers, it may indicate an issue with the performance of the catalytic converter or the turbocharger wastegate controller.

A catalytic converter is a device that changes the composition of exhaust gases to be less toxic. In the United States, catalytic converters are installed in most vehicles manufactured after 1975. A turbocharger wastegate controller is a valve that routes exhaust gases away from a turbocharged engine system’s turbine wheel. This regulates the maximum boost pressure to reduce any lag time before the turbocharger kicks in when operating a vehicle equipped with such an engine.

It may also be associated with other codes, such as P2562.

What the P2565 code means

While the P2565 code itself simply indicates a specific open circuit detected by the engine control module (ECM), this open circuit is likely caused by an issue in the operation of the turbocharger wastegate controller.

What causes the P2565 code?

A problem with the catalytic converter or turbocharger wastegate controller, such as having a leak or an issue with sticking, triggers an open circuit signal from the B rocker arm actuator. The ECM detects this signal and then registers the P2565 code and illuminates the Check Engine Light.

What are the symptoms of the P2565 code?

The P2565 code triggers the Check Engine Light to come on and may be accompanied by the following symptoms:

  • Lag time in the engagement of the turbocharger, if applicable
  • Reduced fuel efficiency
  • Vehicle may not start or stay running

How does a mechanic diagnose the P2565 code?

A qualified technician is able to use a specialized scan tool to verify the existence of the P2565 code and collect further data that helps to interpret the cause of this OBD-II trouble code registering. This scan tool differs from those found in auto parts stores in the breadth of its scope and accuracy of its data, which is why the tool is only distributed to certified technicians.

A mechanic in possession of such a tool and trained in its use may perform multiple tests to determine whether the underlying issue was a one-time occurrence or an ongoing one. The technician may also perform a manufacture pinpoint test to eliminate any doubt surrounding the validity of the P2565 code.

Common mistakes when diagnosing the P2565 code

There are three common mistakes a technician may make in the diagnostic process after the P2565 code has registered:

  • Neglecting to verify the open circuit in the B rocker arm actuator

  • Failing to perform a thorough visual inspection of the catalytic converter, turbocharger wastegate controller (if installed), and related components

  • Forgetting to clear the P2565 OBD-II fault code after making repairs

How serious is the P2565 code?

Since the P2565 code is related to systems that control the flow and output of toxic gases, problems negatively impact the safety of those near the vehicle when running as well as the environment. Although some symptoms related to this code are relatively minor, others are major enough to prevent the vehicle from running at all. Consequently, do not neglect to seek an inspection and diagnostics from a trained professional once the P2565 code has registered.

What repairs can fix the P2565 code?

Once a trained technician in possession of tools like an advanced scan tool has validated the P2565 code, one or more of the following repairs may be needed:

  • Repairing the connector to the actuator or its wiring harness
  • Replacing the B rocker arm actuator
  • Replacing the catalytic converter
  • Replacing the turbocharger wastegate controller on a vehicle with a turbocharged engine

Additional comments for consideration regarding the P2565 code

Any time an OBD-II fault code, such as P2565, registers, it can take up to several hours for a technician to validate that code and perform a visual, hands-on inspection to locate the cause of the issue triggering the code. Multiple tests may be required, and it may take time to make sure other issues are not present. It is worth the extra time needed to perform a full inspection to make sure other repairs not indicated by the trouble code aren’t also necessary and can also save you another costly trip to the mechanic.

He called to come earlier which was fine. He was very pleasant and able to help me with my older 1989 Mini Itasca RV which has a Toyota pickup front and engine. I couldn't find any shops that would service it. He found the codes and problems. I made an appointment with him for the parts and repairs from his trouble shooting.
