P2011 Code: Intake Manifold Circuit Open (Bank 2)

Check Engine Light is on, and you’ve pulled code P2011. If you drive a V6 or V8 vehicle (like a Ford F-150, Mercedes, or Audi), this means one side of your engine has lost connection with its intake control system. It’s an electrical fault, specifically on Bank 2.

What Does P2011 Mean?

P2011 stands for "Intake Manifold Runner Control (IMRC) Circuit Open Bank 2."

The IMRC system uses solenoids to open and close flaps in the intake manifold. "Circuit Open" means the wire is cut, the connector is unplugged, or the solenoid coil is burnt out. The computer tries to send a signal, but it hits a dead end.

For a basic understanding of what an "Open Circuit" is in electronics, check out this guide.

🔄 The "Twin Codes": P2011 vs. P2008

If you are confused about Bank 1 vs. Bank 2, here is the breakdown:

P2008: Circuit Open on Bank 1 (Side with Cylinder 1). Read the P2008 Guide here.
P2011: Circuit Open on Bank 2 (The opposite side).

Note: If you ignore P2011, the mechanical flaps will not open, which will eventually trigger Code P2007 (Runner Stuck Closed Bank 2).

Why Did Bank 2 Lose Connection?

Since P2011 is specific to Bank 2, you can ignore the Bank 1 wiring. The problem is usually localized:

Unplugged Connector: If you recently did maintenance (like changing spark plugs or valve cover gaskets) on the Bank 2 side, check the connectors. It is very easy to forget to plug the IMRC solenoid back in.
Broken Wire near Connector: The wires entering the solenoid plug are often bent at sharp angles. Vibration can cause the copper wire inside to snap, creating an open circuit.
Failed Solenoid: The Bank 2 solenoid might have overheated and failed internally.

Diagnosing P2011 with iCarsoft CR Ultra P

You need to confirm if the issue is the wiring harness or the solenoid itself. The iCarsoft CR Ultra P makes this easy with Active Tests.

The "Bank 2" Click Test

Step 1: Connect the CR Ultra P and turn the Key ON (Engine Off).
Step 2: Go to Actuation Test > Intake Manifold Runner Control Bank 2. (Make sure you select Bank 2, not Bank 1).
Step 3: Toggle the command ON and OFF.
Step 4: Listen to the solenoid on the Bank 2 side of the engine.
- No Click? Disconnect the solenoid and plug a test light into the harness connector. Run the test again.
  - If the light flashes, the Wiring is Good, and your Solenoid is Dead. Replace it.
  - If the light does not flash, you have a broken wire leading back to the ECU.

Frequently Asked Questions

How do I find Bank 2?

Bank 2 is the cylinder bank that does not contain Cylinder #1. On a transverse V6 (like in a minivan or crossover), Bank 2 is often the "Front" bank closer to the radiator, making it easier to access than Bank 1.

Does P2011 affect fuel economy?

Yes. If the intake runner control is disconnected, the flaps will default to a specific position (usually closed). This restricts airflow at high RPMs, causing the engine to struggle and potentially run rich.

Can I repair the solenoid wiring?

Absolutely. If you find a broken wire near the connector (a common issue on older Ford and Audi models), you can solder in a new "pigtail" connector rather than replacing the entire engine wiring harness.

Fix the circuit, restore the power.
