check engine light

P2660 code definition

The P2660 Trouble Code means that there is an issue with the B rocker arm actuator control circuit/open bank 2.

What the P2660 code means

When the code appears, it means that there is an open circuit or a short that’s been detected in the rocker arm actuator control circuit for the exhaust B camshaft in engine bank 2.

What causes the P2660 code?

The following are some of the most common causes of the P2660 code:

  • Faulty oil control valve.
  • Open electrical circuit/connector that’s related to the oil control valve.
  • Faulty powertrain control module.
  • Having low oil pressure can also be a contributing factor to this issue.

What are the symptoms of the P2660 code?

Drivers will know that there is a problem with their vehicle because their Check Engine light will come on. The vehicle will also feel very rough when it is idling, and you will likely notice that there is a decrease in the engine performance. The acceleration may no longer be smooth either.

How does a mechanic diagnose the P2660 code?

The mechanic will connect their OBD-II device to the vehicle. It connects to the onboard computer, and then gathers data from the car. This will let the mechanic know what codes are present and what issues might be at play in the vehicle. They will then rest the codes and test drive the vehicle. This gives them a chance to see how the vehicle is running, and if the code returns, they have a better idea of what the problem might be. After that, they can begin with potential repairs.

How serious is the P2660 code?

The vehicle will often be more difficult to drive when the P2660 code is present. As mentioned, the vehicle will not run as smoothly as it did, particularly when idling. When you are trying to accelerate, it can often feel as though it is chugging. In addition, you will have to contend with the Check Engine light, which will likely stay on.

What repairs can fix the P2660 code?

The following are some of the things that a mechanic might do to repair the vehicle:

  • Check the electrical connections.
  • Test the circuits.
  • Replace circuits, connectors, and other components that are not behaving according to the manufacturer’s instructions.
  • Reset the code and test the vehicle again. If there are no issues present in the vehicle, but the light returns, they may need to replace the powertrain control module.

Additional comments for consideration regarding the P2660 code

When you notice that there is an issue with your vehicle, even if it seems minor, it is important that you take the time to bring it to a mechanic. The mechanic can diagnose the problem and help to fix the P2660 code. Even if you don’t notice any issues with the vehicle right away, they could present themselves later. It’s better to get the vehicle fixed as soon as possible.
