P2006 trouble code definition

The P2006 code is a generic OBD2 diagnostic trouble code relating to the intake manifold runner control circuit.

This code is similar to the P2005, P2007, P2008, P2009, P2010 and P2015.

What the P2006 code means

The P2006 code means that the intake manifold runner control circuit has detected a stuck closed intake runner flap for bank 1. The ECU tries to control the the intake manifold runner flap position, when the malfunction is detected a Check Engine Light is set.

In addition to the Check Engine Light, the vehicle goes into a failsafe mode. The failsafe mode will remain until the fault is resolved or normal operation is resumed.

What causes the P2006 code?

  • Intake manifold runner that is faulty or clogged
  • Shorted or open wiring harness
  • Intake manifold runner control solenoid that has failed
  • Electrical connection that is poor

What are the symptoms of the P2006 code?

  • Check Engine Light displayed on the dashboard
  • Engine may run poorly
  • Loss of low end engine power
  • Idle that is rough

How does a mechanic diagnose the P2006 code?

  • A scan tool will be hooked into the vehicle’s ECU and checked for any codes. The codes will each have their own freeze frame data which indicates the condition the vehicle was under when the code was set.

  • All codes will then be cleared and a test drive will be performed under similar conditions to the freeze frame data.

  • Then a visual inspection is done to look for any damaged wiring, broken components and worn vacuum lines.

  • Next the scan tool will be used to look at the live data stream and the intake manifold runner position will be monitored while the vehicle is operated.

  • Lastly a vacuum hand pump will be used to test the intake manifold runner control solenoid.

Common mistakes when diagnosing the P2006 code

  • Mistakes can be made when the intake manifold flaps are replaced when the intake runner control solenoid is the cause.

  • All diagnostic steps should be done in the proper order without skipping any. This is done to avoid unnecessary repairs and wasting time and money.

How serious is the P2006 code?

The P2006 code can have some serious symptoms if left for long periods of time. If the intake manifold runner flaps fail engine damage may ensue.

What repairs can fix the P2006 code?

Additional comments for consideration regarding the P2006 code

In some vehicles the intake manifold can be decarbonized which can unstick the intake runner flaps. These cleaners are ran through a vacuum line and breakdown the carbon deposits.
