P2006 - OBD Trouble Code
OBD Code P2006 - Intake Manifold Runner Control Stuck Closed Bank 1
The
trouble code P2006 can be explained as Intake Manifold Runner Control Stuck
Closed 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. One thing which
you must keep in mind that its symptoms as well as causes would surely vary as
it depends upon a number of things. The intake manifold runner control circuit
is being monitored by the engine control module. This trouble code would be set
by the ECM when the intake manifold runner control circuit would not be as per
the specifications set by the manufacturer. Now when this malfunction is
detected, then it would give rise to a check engine light.

This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code. This trouble code would mean that a stuck closed intake runner flap for bank 1 has been detected by the intake manifold runner control circuit. It is the ECU which would try to control the intake manifold runner flap position.
What causes this problem with the Intake Manifold Runner Control Stuck Closed Bank 1?
- Intake manifold runner that is defective or blocked
- Wiring harness might be unlocked
- There can be inoperative Intake manifold runner control solenoid
- Bad electrical connection
Replace/Repair These Parts To Fix Code P2006
- Intake Manifold
Actuator – Actuator for an intake manifold tuning valve is used to regulate
airflow in an intake manifold of an internal combustion engine. The actuator
includes a motor, control circuit, and sensor all mounted in a housing that has
an opening through which an output shaft extends. Thus, replace the faulty
actuator immediately.
- Engine Control
Module – ECM faults are rare but can be a big problem as faulty ECM will cause
wrong vehicle operations and can also result in wrong OBD codes getting stored
in the system which can also cause misdiagnosis. Thus, replace faulty ECM
components now!
- Electronic Control
Unit – The ECU coordinates with the temperature sensor to control the blower
fan for keeping the battery temperatures under control. So, replace faulty ECU
components now!
- Intake Valve – An Intake Valve is
a spring action valve that is placed on a cylinder head of an internal
combustion engine just next to the spark plug and exhaust valve. Its main
purpose is to allow the proper amount of air-fuel mixture to enter inside the
cylinder when the complete movement cycle of piston from TDC (top dead center)
to BDC (Bottom Dead Center) and back to TDC takes place. Thus, replace damaged
valve today!
- Intake Manifold - When the intake
manifold fails, it can leave the engine without the increased performance, and
in some cases even reduce performance. Usually a faulty intake manifold will
produce a few symptoms that can alert the driver of a potential issue. Thus,
replace damaged component now!
- Powertrain Control
Module – Check for PCM error which might be due to circuit faults that might
require complete replacement and reprogramming. Replace it now!
- Diagnostic

Easy Diagnosis Of Engine Error OBD Code P2006
Here are some steps which you should follow in order to diagnose this fault code:
You must always start with a technical service bulletin search for your particular vehicle. Advanced diagnostic steps become very vehicle specific and may require the appropriate advanced equipment and knowledge to perform accurately. We include basic steps below but refer to a vehicle year/make/model/powertrain specific repair guide for specific steps for your vehicle. The diagnosis should be started by the visual inspection of system wiring as well as connector. An open circuit can be caused due to corrosion in the IMRC actuator connectors, so it is essential to pay attention to these. A scanner should be used by a professional technician to notice the freeze frame data, to assemble details about the code. The mechanic can also check to see if there is presence of additional trouble codes. Now if there are a number of codes, then they should be addressed in the same order in which they are appearing on the scanner. After that the mechanic should reset the trouble codes, restart the vehicle, and check to see if the code remains detected.
If it does not, then the code was likely triggered incorrectly, or represents an intermittent issue. Now once the code is reset, access should be gained for IMRC actuator solenoid and IMRC runner position sensor. One can always consult a vehicle information source for checking recommendations for these constituents. A DVOM should be used to perform a resistance test on both constituents. If the actuator or the position sensor are not as per the specifications set by the manufacturer, then the faulty parts should be replaced and then retest the entire system once again. If the actuator resistance and sensor resistance are both as per the specifications set by the manufacturer, then a DVOM should be used to check the resistance and continuity on all system circuits. You can always avoid the controller damage; this can be done by disconnecting all related controllers before testing. Repair or restore the shorted or open circuits as per the requirements. Check the IMR flap binding with the actuator disconnected from the shaft. The screws or rivets that secure the flaps to the shaft may loosen or fall out causing the flaps to bind. Binding can be caused due to carbon coking inside the intake manifold walls.
Common Mistakes When Diagnosing The P2006 Code
- Common mistakes while diagnosing this trouble code are unnecessary and expensive replacements which usually happen when one don’t follow all the steps carefully. In this code usually mechanic replaces intake manifold flaps when in reality the issue lies with the ake runner control solenoid.
