How do I fix P1538 intake manifold control runner stuck open bank 2

Intake Manifold runner control stuck open - bank one:
- 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

There is a factory service bulletin for this problem for 2007-2008 Dodge Avengers. (JS)

code p2004 refers to intake manifold air control actuator bank 1---actuator stuck open===causes --wiring--intake manifold air control actuator --mechanical fault.
also refers to intake manifold air control solenoid bank 1 solenoid stuck open===causes--wiring intake manifold air control solenoid --- mechanical fault
you may be able to remove and clean the units to ensure they move freely otherwise replace them

code p 2004 has two references
intake manifold air control actuator , bank 1 --actuator stuck open====causes ---wiring---intake manifold air control actuator ---mechanical fault
second reference is
intake manifold air control solenoid , bank 1 --solenoid stuck open===causes ---wiring--intake manifold air control solenoid ---mechanical fault
probably means the same as what you have but in a more easy to understand method

Your engine has IMRC (intake manifold runner controls) that are supposed to stay closed under 3000 rpms. Over time they get carboned up and can hang open causing poor performance. Try to manually close the valve, if it immediately opens again the diaphragm might be bad. It would require replacing that IMRC.

they are a ford specific codes they both are the same also :intake manifold runner control stuck open---the control is in the upper section of the manifold it may be stuck by sludge ,debris or carbon can try a carb spray cleaner if dont work may have to have repaired or replaced good luck

These are all related:
P1537 and P1538 are BOTH:
Intake Manifold Runner Control Stuck Open
P0171 is Lean Bank #1
P0174 is Lean Bank #2.
On the front of the Intake Manifold there are Plastic Clips. The Clips are currently broken and need to be replaced. Because these are broke the Computer is registering too much Air or not enough Fuel = Lean.
You should be able to purchase these at any auto parts store (call ahead for availablility).
After you replace these, all the Codes should disappear.
Let me know if this helped, or if you have addtional information or questions. Feel free to contact me at FixYa.com!

LOOKING IN CODE BOOK.POSSIBLE CAUSE TO YOUR PROBLEM THE IMRC COULD BE STUCK OPEN.OR THE IMRC ACTUATOR IS DAMAGED OR HAS FAILED.ALSO THE IMRC MONITOR SIGNAL CIRCUIT COULD BE SHORTED TO POWER GROUND OR SHORTED TO SIGNAL GROUND RETURN.

It could all be related.P1537/38 are the intake manifold runner controls are stuck open.They are controlled by vacuum solenoids.The P0171 is bank one of the engine is running lean,usually caused by a vacuum leak, P0420 is catalytic converter efficiency code. The computer monitors the switch rate of the front 02 sensors and compares it to the switch rate of the rear 02 sensors to tell if catalytic converter is doing its job. Now if the front 02 is not switching properly then this will cause this test to fail and set this code.
Look on bottom section of the intake manifold at the back of engine(where tranny bolts up) you should see the vacuum motors there on the intake,these are the control motors for the intake manifold runners.Make sure the vacuum lines are hooked up and lines are not leaking. Also you will see a lever from it to intake make sure they move and are not binding.

HAVE ENGINE CODES P1537 & P1538 WHICH ARE INTAKE MANIFOLD RUNNER CONTROL STUCK OPEN BANKS 1 & 2.
YOU CAN TRY TO CLEAN THEM,BUT ITS NOT LIKELY THAT YOU CAN CLEAR THE CODES.

BUT DONT WORRY THIS PROBLEM IS COMMEN ON THIS MODEL OF FORD.

GOOD LUCK...
