P2647 OBD Error Code: Problem & Solutions

<<See All OBD Codes    

The trouble code P2647 can be explained as A Rocker Arm Actuator System Stuck On Bank 1. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

If the engine control module would detect a variation in the voltage coming from the A rocker arm actuator system stuck on bank 1 that is outside the parameters set by the automobile manufacturer, then it would store the P2647 error code. This would also give rise to the illumination of the check engine light.

What causes this problem with the A Rocker Arm Actuator System Stuck On Bank 1?

• Low or stuffed engine oil
• Inexact engine oil type
• Some issues related to the 'A' Rocker Arm Actuator Sensor
• Unlocked 'A' Rocker Arm Actuator Sensor harness
• Unsatisfactory electrical connection in the 'A' Rocker Arm Actuator Sensor circuit

1. Engine Control Module - If there is any corrosion or breaks in the internal wiring of the harness, then it can cause a short in the ECM or can also cause corrosion in the ECM through the wiring harness. You can always rely on us as we have the best auto parts for our customers.
2. Powertrain Control Module - The onboard computer, or powertrain control module is the brain of the engine control system. Now if the brain is not working properly, then neither is the car engine. Get it replaced before the situation gets worse.
3. Electronic Control Unit - Is your car jump starting on reverse polarity? Or are you facing some intermittent starting issues? If yes, then it indicates that your electronic control unit is bad. So it is very important to replace the defective electronic control unit with us at equitable prices.
4. Fuel Injector - The fuel injectors are an important component of the fuel delivery system that helps in proper utilization of the fuel entering the engine. This not only helps in taking care of the air to fuel ratio in the engine, helping the combustion process but also enhances the performance. Thus, replace faulty injector now!
5. Diagnostic Tools - Buy quality diagnostic tools to check and diagnose OBD code P2647 error with the help of experienced mechanic. Visit us today!

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2647 code to be stored:

• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• The vehicle’s computer should be inspected with a scanner in order to find out whether there are other accompanying codes, and whether they return after being cleared and then the vehicle should be taken out for a test drive.
• Examine the oil level and pressure.
• The oil pressure sensor and rocker arm actuator screens should be visually inspected.
• Carefully examine the wiring and connections involved in the oil pressure sensor and rocker arm actuator.
• The circuitry with a voltmeter should be tested.
• Monitor the live data waveform patterns with an oscilloscope

Common Mistakes When Diagnosing The P2647 Code

• Malfunctioning powertrain control module
• There can be a failure in the variable valve lift controller assembly
• Wiring problems
