If you notice the engine light on or service engine soon warning light, it could be a sign of p2649 fault code. Here are the symptoms to look out for:

  • The P2649 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include a decrease in engine power, rough idling, stalling, or difficulty starting the engine.
  • The vehicle may also experience poor acceleration or reduced fuel efficiency.
  • Additionally, the driver may notice a decrease in overall performance or a lack of response when pressing the accelerator pedal.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code p2649 can be caused by a variety of factors, including low or overfilled engine oil, incorrect oil type, and faulty actuator components.

  • The automobile fault code P2649 can be caused by low or overfilled engine oil.
  • It can also be caused by using an incorrect engine oil type.
  • Another cause of this fault code is a faulty ‘A’ Rocker Arm Actuator.
  • Additionally, an open or shorted ‘A’ Rocker Arm Actuator harness can cause this fault code.
  • Finally, a poor electrical connection in the ‘A’ Rocker Arm Actuator circuit can also be a cause of the P2649 fault code.

To fix the p2649 fault code, check the possible causes and inspect related wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p2649, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P2649 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

Therefore, the total cost of diagnosis and fixing the P2649 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The P2649 code is related to the Rocker Arm Actuator circuit in the engine. The Engine Control Module (ECM) controls the oil hydraulic circuit through the Rocker Arm Actuator.

The Rocker Arm Actuator adjusts the engine’s valve timing through the variable valve timing system. The P2649 code is set by the ECM when the ‘A’ Rocker Arm Actuator circuit is out of factory specifications. This code indicates that the ‘A’ Rocker Arm Actuator Control Circuit High Bank 1 is not functioning properly.

What are the possible causes of the P2649 fault code?

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2649 fault code. This code can be caused by low or overfilled engine oil, incorrect engine oil type, faulty ‘A’ Rocker Arm Actuator, ‘A’ Rocker Arm Actuator harness being open or shorted, or poor electrical connection in the ‘A’ Rocker Arm Actuator circuit. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector’s pins.

How can I fix the P2649 fault code?

If you’re experiencing the P2649 fault code, indicated by the engine light or service engine soon warning light, there are a few possible causes to consider. These include low or overfilled engine oil, incorrect engine oil type, a faulty ‘A’ Rocker Arm Actuator, or an open or shorted ‘A’ Rocker Arm Actuator harness. To fix the issue, visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

Can low engine oil cause the P2649 fault code to appear?

Yes, low engine oil can cause the P2649 fault code to appear. This fault code is related to the ‘A’ Rocker Arm Actuator, and low engine oil can cause this actuator to malfunction. Other possible causes include incorrect engine oil type, faulty actuator, or poor electrical connection. To fix this issue, it is recommended to visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
