Error Code P2006 – Symptoms, Causes and Solutions.

The fault code P2006 can be explained as Intake Channel Control Stuck in Bank 1. This diagnostic fault code is a generic powertrain code, meaning it would apply to OBD-II equipped vehicles.


Specific repair steps may vary as it depends on the make and model of the vehicle. One thing you should keep in mind is that their symptoms as well as causes They would surely vary, since it depends on a series of things. The intake manifold control circuit is monitored by the engine control module.

This fault code is set by the NDE when the intake manifold control circuit is not in accordance with the specifications established by the manufacturer. Now, when this malfunction is detected, then it would result in a check engine light.

More information about OBD error code P2006

This error code is generic which means it can be applied to all vehicles that are equipped with the OBD-II or vehicles made from 1996 to the present.

Specifications regarding definition, troubleshooting steps, as well as repairs can always vary from one vehicle brand to another. This can occur for many reasons and the mechanic must diagnose the specific cause of this code.

This fault code would mean that the intake manifold control circuit has detected a closed intake gate in the bank 1. It is the ECU that attempts to control the position of the intake manifold flap.

What causes this problem with bank 1 closed intake channel control?

  • The intake manifold channel is defective or blocked.
  • The wiring harness may be unlocked
  • There may be an inoperative intake runner control solenoid.
  • Faulty electrical connection

Replace/repair these parts to fix code P2006

  • intake manifold actuator -An intake manifold adjusting valve actuator is used to regulate air flow in an intake manifold of an internal combustion engine. The actuator includes a motor, a control circuit and a sensor, all mounted in a housing that has an opening through which an output shaft extends.
  • Engine Control Module – ECM failures are rare but can be a big problem as a faulty ECM will cause erroneous operations in the vehicle and can also result in wrong OBD codes being stored in the system, which can also cause misdiagnosis.
  • Electronic Control Unit – The ECU coordinates with the temperature sensor to control the fan to keep the battery temperature under control.
  • Admission valve – An intake valve is a spring-action valve that is placed in the cylinder head of an internal combustion engine right next to the spark plug and exhaust valve. Its main purpose is to allow the proper amount of air-fuel mixture to enter the interior of the cylinder when the complete piston movement cycle from TDC (Top Dead Center) to BDC (Bottom Dead Center) and back to TDC is completed. performed.
  • Intake manifold – When the intake manifold fails, it can leave the engine without increased performance, and in some cases even reduce performance. Typically, a faulty intake manifold will produce some symptoms that can alert the driver to a possible problem.
  • Powertrain control module – Checks for an error in the PCM which may be due to circuit failures that may require a complete replacement and reprogramming.
  • Diagnostic tool – To detect the error, high-quality diagnostic tools are needed.

Symptoms of OBD error code P2006

It is vital to know the symptoms of a problem as only then you be able to solve the problem. So that’s why we have listed some of the main symptoms of OBD code P2006 here:

Common symptoms:

  • Service Engine Soon Light Appearance
  • The engine may not run properly
  • Engine power loss at low speed
  • Appearance of irregular idle

How to Fix P2006 Intake Manifold Spool Control Stuck Bank 1 Problem

Looking for some ways with the help of which you can fix this fault code? Then you have come to the right place. We are here to help you, so check the steps mentioned below as follows:

  • It is essential to restore the faulty intake manifold
  • Repair or replace the power train control module
  • Rehabilitate faults in the electrical connection
  • Adjust faults in the ECU
  • The operation of the wiring harness must be restored
  • Inoperative Intake Manifold Channel Control Solenoid Needs Proper Service

Easy Diagnosis of Engine Error OBD Code P2006

Here are some steps you need to follow to diagnose this fault code:

You should always start with a search for technical service bulletins for your particular vehicle. Advanced diagnostic steps are very vehicle specific and may require the appropriate advanced equipment and knowledge to perform accurately.

We’ve included the basic steps below, but refer to a vehicle year, make model, and powertrain-specific repair guide for steps specific to your vehicle. Diagnosis should begin with a visual inspection of the system wiring, as well as the connector.


An open circuit can be caused due to corrosion on the actuator connectors. IMRC, so it is essential to pay attention to these. A professional technician must use a scanner to observe the data of the freeze frame to gather details about the code.

The mechanic can also check for the presence of additional trouble codes. Now, if there are a series of codes, then they must be processed in the same order in which they appear on the scanner. After that, the mechanic should reset the trouble codes, restart the vehicle, and check if the code is still detected.

If it does not, the code may have been activated incorrectly or may represent an intermittent problem. Now once the code is reset the actuator solenoid must be accessed IMRC and to the IMRC runner position sensor. You can always consult a vehicle information source to verify recommendations for these components.


You must use a DVOM to perform a resistance test on both components. If the actuator or position sensor does not conform to the specifications set by the manufacturer, then the defective parts must be replaced and the entire system retested once again.

If the actuator resistance and sensor resistance are in accordance with the specifications established by the manufacturer, then a DVOM should be used to check resistance and continuity in all system circuits. Controller damage can always be avoided; This can be done by disconnecting all related drivers before testing.

Repairs or restores open or shorted circuits as required. Check the fin fixation IMR with the actuator disconnected from the shaft. The screws or rivets that secure the fins to the shaft can loosen or fall off causing the fins to bind. Clogging can be caused by carbon coking within the walls of the intake manifold.

Common errors when diagnosing the P2006 code

The most common errors when diagnosing this trouble code They are the unnecessary and costly replacements that often occur when all steps are not followed carefully.

In this code, the mechanic usually replaces the intake manifold flaps when the problem is actually with the intake runner control solenoid.
