P2006 code

Hi, I checked solenoid, it works, there is vacuum, to diaphram, it works under vacuum pressure also, but when I measure the voltage coming to solenoid to was 1.6 v, does this mean ecu faulty then?

My car has 99000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
When you got a 1.6 volt reading from the test you did, this is not a normal test done for this code. Only a proper pinpoint done by a manufacturer approved test procedure would be able to diagnose the system for you and keep you from replacing the parts that are not needed.

If you need help with this, consider YourMechanic, as a certified technician will help you diagnose your trouble code and suggest a proper fix from there.

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.
Essentially, this is the part that controls how fuel gets pumped into the part of the engine that combusts fuel to produce power. This system is controlled by the powertrain control module, which means if the actuator is stuck open, it might be a problem with either the intake manifold or the powertrain control module.
Common signs include difficulty starting the engine, the Check Engine Light coming on, engine misfires, and a decrease in power and acceleration.
Aside from a decrease in engine performance, some other common symptoms include a reduction in fuel economy, and you may experience the engine surging or sputtering when turned on.
Can I Still Drive with a P2006 Code? As long as the car is still running and doesn`t seem to be having major drivability issues, you can almost certainly drive your vehicle to the repair shop to get it looked at. However, experts don`t recommend leaving this code and driving around with it.
The runner position sensor, also known as the runner valve, controls the volume of air entering the intake manifold. The runner valve controls a flap in the intake manifold, which will open or close depending on the air requirements of the engine.
Can You Continue to Drive with a Bad Intake Manifold Runner Valve? Technically, you can usually drive with a bad IMRC valve. But you shouldn`t continue to do so for long. As previously mentioned, the problem can trigger the check engine light—and that will cause your car to fail a state emissions test.
One of the clearest indicators of an exhaust manifold leak is strange noises coming from the engine. The engine might sound louder than usual as the gasses escape, or you may notice a tapping noise. The ticking or tapping sound happens right after turning on the car.
Definition: Intake manifold runner control stuck closed bank 1. The P2006 engine fault code indicates a problem with your car`s intake air process—specifically the manifold runner control flap for engine bank 1.
Can You Continue to Drive with a Bad Intake Manifold Runner Valve? Technically, you can usually drive with a bad IMRC valve. But you shouldn`t continue to do so for long. As previously mentioned, the problem can trigger the check engine light—and that will cause your car to fail a state emissions test.
The Intake Manifold Actuator is mounted on an Intake Manifold that acts as a passage of air that is sucked into the cylinder of the engine.

Check engine light. Code P2004 (Air Intake manifold. Runner control stuck open, bank 1.)
ANSWER : As you know this code is related to the intake manifold and may be caused by several potential issues such as the following:

Intake Manifold Runner Binding Or Sticking

Faulty Manifold flow valve

Manifold flow valve harness is open or shorted

Manifold flow valve circuit poor electrical connection

It sounds like you have addressed the majority of these. You may want to double check all connections again to be sure they are free from residue from the carb cleaner as sometimes this can cause connectivity issues with electrical components.

P2006 Code (Replace Intake Manifold Runner Actuator)
ANSWER : This will not blow your motor up – it will degrade engine performance however, as you have already noted. The specific code suggests this valve is stuck shut. It may be possible to test this "off the vehicle", but remember it is activated under real-time performance conditions, and test conditions may not adequately duplicate running conditions. If you’d like assistance in diagnosing and repairing this issue, a YourMechanic certified technician can come to your location to perform a Check Engine Light is On Inspection on your vehicle.

Intake Manifold Runner Control Stuck Closed Bank 1
ANSWER : Depending on the year, make, model and engine you have the intake manifold runner control valve and sensor is located on the intake manifold. The stuck closed control means that the air flow control plates are in the closed position and do not open. The system is designed to increase or decrease air flow into the engine cylinders. The addition of air will need addition of more fuel to go with the extra air and will give the engine more power like when accelerating or passing another vehicle. This also uses more fuel during this adding of more fuel and air. When the valve is closed it reduces the amount of air getting into the cylinders. The less air requires less fuel and will give you less power for less demanding situations like cruising at a steady speed or idling. This will give you better fuel mileage but less power on acceleration or for passing another vehicle.

Oil is geting into intake manifold and into all intake vavles.
ANSWER : Hi there. That type of oil volume inside the intake manifold is typically a sure fire indication of a blown head gasket. It’s also quite possible that this has occurred for an extended period of time. There are a few things that you can do to verify that this is the head gasket. First, check the oil itself. If it is milky or foamy then it means the head gasket is damaged and coolant is leaking into the oil galleys. If the head gasket is not damaged, excessive oil inside the spark plug well could also be a damaged O-ring but can also be the result of a failing piston or worn valve guides. Either way, the only way to correctly inspect and diagnose this would be to tear down the motor, so you might want to consider whether you are wanting to complete repairs or purchase a newer vehicle.

I went to AAmco because my engine light was on! They did a diagnostic and came up with 2 codes. intake runner position sensor cir
ANSWER : Diagnostic Trouble Codes, such as the two codes that were retrieved at the first shop, cannot be used to "directly" condemn parts. Rather, these Codes are merely clues that are used to inform an actual diagnostic. But, short of an actual diagnostic, nothing can be intelligently concluded about which part or component has failed. In the case of the Intake Manifold Runner Control (IMRC) system, there are quite a few components that have to be directly tested, and ruled in or out, before any repair decision is made. PCM’s rarely fail (computer brain you are referring to) by the way. As far as the second shop, you should request tangible evidence of a faulty part, that is actual documentation and a credible explanation, prior to letting them do anything. Just to give you an idea of the number of possible causes of the check engine light coming on, if there is an IMRC fault, here is just a partial list of possible underlying causes, all of which have to be looked at: IMRC solenoid that is defective, IMRC solenoid wiring that has shorts, breaks, or is frayed, IMRC solenoid circuitry that has shorted or is open, IMRC solenoid connector that is corroded, IMRC butterfly valve plate screws that are loose or broken, IMRC butterfly valve plates that are broken, IMRC butterfly valves plates that have disconnected from the IMRC actuator, Vacuum control solenoid vacuum filter that is clogged, Debris in the vacuum control solenoid, Vacuum lines that are disconnected or broken, Carbon buildup on the IMRC butterfly valve plates, Exhaust gas recirculation (EGR) valve trouble codes that have been stored by the PCM, MAF sensor trouble codes that have been stored by the PCM, and BARO sensor trouble codes that have been stored by the PCM.

If you want an authoritative diagnostic, and an explanation of exactly what has failed and caused the check engine light to remain on in your car, please request an IMRC system diagnostic and the responding certified mechanic will get this problem resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Intake manifold runner stuck closed bank 1. How can I fix this on my car
ANSWER : There are several parts that might be broken that will cause this. The best case scenario is that you have a vacuum line disconnected. Check all your vacuum lines and hose connections first. However, what is much more likely is that the vacuum motors or the manifold flap itself are broken. There are a number of repair kits from the aftermarket that upgrade from plastic to metal parts, but installing them involves removing the intake manifold, so it can be a big job. If you contact Your Mechanic you can have a technician come out to your home or office and do this intake manifold repair for you

I have a Code P0601 on the PCM. I replaced the PCM, and now I have a code P0118, code P0123, and code P0193.
ANSWER : Hi there, the short answer to your question is no . A PCM with a P0601 (which is a memory module error in the PCM) cannot reliably retrieve codes for the codes you list (P0118 – coolant temp sensor, P0123 – throttle position sensor, P0193 – fuel rail pressure sensor.

Most likely, the P0601 prevents the PCM from getting any codes from the engine sensors. The memory module error may cause in data corruption for collected sensor values, lose of data over multiple sampling periods, or failure of the data collection to work at all. Replacing the PCM was a necessary expense.

If you need assistance with the "new" codes, I would recommend having a Check Engine Light inspection completed by a mobile, professional mechanic, such as one from YourMechanic, to diagnose the new error codes and get an accurate assessment of the repairs needed.

Can i retrieve CEL code from car … forgot what code it hade in my car .. put headgasket sealer and i erase the code ..
ANSWER : Once a trouble code is erased, it cannot be retrieved. The engine controller does not have a "recycle bin" like they have on Windows. If the car still has a problem, the code will come back up after some driving. However, the controller will not turn on the CEL until it has seen the malfunction on two separate "trips." A "trip" is a driving cycle where the car is started cold, driven until it is fully warm and through a certain number of accelerations, and shut down. So you might not see the CEL for a couple of days. As for the "head gasket sealer," I wouldn’t hold out too much hope of that solving a problem. At the very best it might put off the symptoms for a short while. If you need help interpreting codes that come up, or solving a head gasket issue, contact Your Mechanic. They can send a technician to your home or office to read the codes on your car and help you decide what to do.
