P2013Generic code

P2013 Code: Intake Manifold Runner Control Circuit High (Bank 2)

The P2013 code means high voltage in the control circuit of the bank 2 intake manifold runner control valves, from an open circuit or a short to voltage. It can cause a loss of torque at low rpm and a slightly rough idle. The engine runs, with a little less performance.

What the P2013 code means

Many engines have flaps or valves in the intake manifold (IMRC, Intake Manifold Runner Control, also called swirl or tumble flaps) that change the length or shape of the intake runner. At low rpm they close so the air enters faster and with more turbulence, which improves torque and combustion. At high rpm they open to let more air through. An electric motor or a vacuum actuator controlled by a solenoid moves them, and a position sensor tells the computer whether they really moved.

The computer watches the control circuit from its own driver transistor. The P2013 code means high voltage in the control circuit, from an open circuit or a short to voltage. Before you replace the component, check the fuse, the relay, the connector and the wiring, because they are the most common cause.

The computer does the commanding on an electric actuator or on the solenoid that supplies vacuum to the pneumatic actuator. Bank 1 is the side of the engine where cylinder number 1 is. Inline engines only have bank 1. On V engines, bank 2 is the opposite side.

To confirm the diagnosis, measure the continuity of each wire between the component connector and the computer connector with the key off. It should be under 1 ohm, and an infinite reading means the wire is open. If the wiring checks out, measure the component itself: infinite resistance confirms that it is open inside.

P2013 code symptoms

  • Check engine light or another warning light on.
  • Loss of torque at low rpm and a slightly uneven idle.

Likely causes of the P2013 code

  1. Connector loose or broken. The most frequent cause, especially after another repair.
  2. Coil or motor open. The resistance reads infinite.
  3. Control wire cut between the component and the computer.
  4. Short to 12 volts. The control wire touches another wire that carries voltage.

How to diagnose the P2013 code step by step

  1. Activate the component with the scan tool and check whether it responds.
  2. Check the fuse and the relay. Measure voltage on both sides of the fuse, and swap the relay with an identical one.
  3. Measure the supply at the connector. You should see battery voltage with the key on or when it is activated.
  4. Measure the resistance of the component and compare it with the manual. Check the insulation to ground too.
  5. Check the control wire. Look for continuity all the way to the computer and for any short circuit.

How to fix the P2013 code

  • Repair the connector, the wiring or the power supply.
  • Replace the intake manifold runner control valves if they do not respond with correct power and control.
  • Clear the codes and verify.

Technical reference data

  • Vacuum actuator: it should hold about 15 to 20 inHg without losing vacuum for one minute.
  • Electric actuator: 12 volt supply, with control by a PWM signal or by reversing polarity.
  • Position sensor: 5 volt reference and a signal of roughly 0.5 to 4.5 volts depending on the flap position.
  • These values are only a guide, so look up the manufacturer data for your vehicle.

Brand-specific notes

On some diesels the flaps fill up with carbon and can break. A fragment inside the cylinder can cause a serious failure, so some shops remove the flaps following manufacturer procedures.

P2013 on Ford and Mazda

This code is frequent on Ford Duratec and Mazda MZR gasoline engines.

P2013 on Volkswagen, BMW, Mercedes-Benz and Fiat

It is also frequent on the diesel engines with swirl flaps from Volkswagen, BMW, Mercedes-Benz and Fiat.

P2013 on GM V6 Engines

Several GM V6 engines are also known for this code.

Frequently asked questions about P2013

Can I drive with a P2013 code?
Yes. The engine runs, with a little less performance.
What do the intake manifold runner control valves do?
They are flaps in the intake manifold (IMRC, also called swirl or tumble flaps) that change the length or shape of the runner. At low rpm they close so the air enters faster and with more turbulence, which improves torque and combustion. At high rpm they open to let more air through.
Does the part always have to be replaced?
No. Check the fuses, relays, connectors and wiring first.
How much does it cost to fix P2013?
Roughly $40 to $450.
What does the P2013 code mean?
It is a generic OBD2 code that means the control circuit of the bank 2 intake manifold runner control valves has high voltage, from an open circuit or a short to voltage.
Will a P2013 code clear itself?
Only if the cause was a passing glitch, such as a connector that was briefly loose. A cut wire or an open coil will bring the P2013 code back.
What is the most common cause of P2013?
A loose or broken connector, especially after another repair. Look at the connector first, then the control wire and the coil.
