P2005: Intake runner flaps stuck open on bank 1

Intake manifold runner control stuck open (bank 1)

Severity: Severity not verified — if the car runs badly, have it inspected

Our sources describe reduced power and rough idle but do not rate how safe it is to drive.

It gets more serious if:

Inspect soon: Inspect soon if the engine loses power, idles roughly or hesitates.

P2005 in short

P2005 means the engine computer sees the intake manifold runner control on bank 1 stuck open. Common causes are a vacuum leak or cracked vacuum hose, a faulty control solenoid, or carbon in the manifold. Expect rough idle or reduced power. Have it checked soon, since severity is not verified.

Some intake manifolds change the length of their air passages with flaps, to help low-speed torque and high-speed power. If the computer sees the bank 1 flaps stuck in the open position, it sets P2005.

REREV lists a faulty runner control solenoid, a damaged vacuum line, a clogged manifold and the computer. Symptoms include rough idle, hesitation and reduced performance.

Ford's bulletin for 2017-2019 F-Super Duty trucks with the 6.2L engine traces P2004 and P2005 to torn or cracked intake manifold vacuum hoses and says to inspect the hoses first.

Most likely causes

Cause 1: Torn or cracked vacuum hose to the runner actuator
Supported by vehicle data
Why it ranks here
Ford's bulletin for 6.2L Super Duty trucks names torn or cracked intake manifold vacuum hoses for P2004 and P2005, and REREV lists a damaged vacuum line.
What would change this
Rises if a vacuum hose is cracked or off, or the actuator does not move with applied vacuum. Falls if hoses hold vacuum.
How to test the vacuum hoses and intake leaks
Cause 2: Runner control solenoid or actuator
Common general cause
Why it ranks here
REREV lists the runner control solenoid first.
What would change this
Rises if the solenoid does not respond to a scan tool command. Falls if it does.
Cause 3: Carbon or debris in the manifold or flaps
Possible — needs testing
Why it ranks here
REREV lists a clogged manifold, but carbon alone is less specific than a vacuum or solenoid fault.
What would change this
Rises if the flaps stick when moved by hand during a shop inspection.
Cause 4: Engine computer fault
Possible — needs testing
Why it ranks here
REREV lists the computer last.
What would change this
Rises only after hoses, solenoid and flaps are ruled out.

What to test first

Start at step 1. Each result tells you what it means and where to go next.

Step 1: With the engine off, look at the intake manifold vacuum hoses for tears, cracks or loose ends.
Low riskTool: flashlight
- IfA hose is torn, cracked or off
  It meansReplace the hose assembly.
  Points to: Torn or cracked vacuum hose to the runner actuator
- IfHoses look fine
  It meansTest the solenoid and actuator.
  Go to step 2
Step 2: Have a technician command the runner control with a scan tool and check the actuator and solenoid movement.
Best left to a shopTool: bidirectional scan tool
Warning:Keep hands away from belts and fans while the engine runs.
- IfThe actuator does not move on command
  It meansReplace the solenoid or actuator.
  Points to: Runner control solenoid or actuator
- IfThe actuator moves freely but the code returns
  It meansHave the flaps and manifold inspected.
  Points to: Carbon or debris in the manifold or flaps

Symptoms

Rough idle
Hesitation or reduced power
Check engine light
Hissing from a vacuum leak

Compare with: Rough idle with the check engine light on

How to fix

Step 1: With the engine off and cool, look over the visible vacuum hoses on the intake manifold for cracks or loose ends.

P2005 questions

What does P2005 usually come down to?

On Ford 6.2L trucks, torn vacuum hoses. In general, a vacuum hose, solenoid or stuck flaps. Inspect the hoses first.
