P2647 code definition

A Rocker Arm Actuator System Stuck on Bank 1

What the P2647 code means

This trouble code indicates that the powertrain control module has detected a malfunction in the intake camshaft rocker arm actuator system (A). This code is usually found in vehicles that have variable valve timing.

What are the causes of the P2647 code?

Some of the potential causes of this trouble code would include:

  • The engine timing may be out of specification

  • A faulty oil control valve or restricted orifice may be a factor

  • Damaged wiring or connector that is associated with the oil control valve may be present

  • Low oil pressure / Low engine oil may be causing this issue

  • A faulty powertrain control module may exist

What are the symptoms of the P2647 code?

  • Hesitation or stumble upon acceleration.
  • Poor engine performance overall

How does a mechanic diagnose the P2647 code?

The first thing a mechanic would do to diagnose this issue would be to check the engine oil level and check for a low oil pressure light. After that the mechanic would ensure that the engine timing is correct using the marks supplied by the manufacturer. If all timing marks appear to be correct, the mechanic would then test the variable valve timing parts to ensure proper function. Next, the mechanic would test all circuitry related to the variable valve timing system. Finally, the mechanic would use a high tech scan tool to test the powertrain control module. If any parts turn out to be faulty during this diagnosis, they would need to be replaced before moving to the next step. The mechanic would likely explain to the customer that multiple parts may need to be replaced and multiple diagnostic tests may need to be carried out.

Common mistakes when diagnosing the P2647 code
