What does the intake manifold runner control do?

The intake manifold runner control is an engine management component that is found on newer intake manifold designs. It is usually a motorized or vacuum actuated unit attached to the intake manifold, that controls the opening and closing of butterfly valves inside of the intake manifold runners.

How do you fix code P2004?

What repairs can fix the P2004 code?

  1. Replacing the IMRC solenoid.
  2. Repairing or replacing IMRC solenoid wiring that has shorts, breaks or is frayed.
  3. Repairing or replacing IMRC solenoid circuitry that has shorted or is open.
  4. Repairing or replacing IMRC solenoid connector that is corroded.

What does intake manifold runner control stuck open bank 1?

P2004 code is set when the PCM believes the IMRC solenoid is stuck in the open position. The intake manifold runner control (IMRC) system is responsible for tuning the airflow inside the intake manifold before that air enters the engine.

What does it mean intake manifold runner control stuck open?

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.

Where is the intake manifold runner control located?

Above and behind the serpentine belt, you’ll find a black box with linkages coming out of it. The box contains an electric motor that controls two doors or flaps in the side of the intake manifold [Ford calls it the Intake Manifold Runner Control].

How long does it take to replace intake manifold?

In most cases, it takes two to four hours for the entire process to be complete. Removing the old intake manifold only takes about 40 minutes, but installing the new one and reassembling takes much longer.

How do I fix code P2008?

What repairs can fix the P2008 code?

  1. Intake manifold runner flaps unstuck.
  2. Wiring harness replaced or repaired as needed.
  3. Intake manifold runner control solenoid replacement.
  4. Repair of poor electrical connection.

What is P2015 code?

Diagnostic Trouble Code (DTC) P2015 stands for “Intake Manifold Runner Position Sensor /Switch Range/Performance (Bank 1).” This code simply indicates that the powertrain control module (PCM) has detected that the signal in the Bank 1 intake manifold runner position sensor is out of range.

How does intake runner length affect performance?

The dimensions are critical to the operating speed of the engine. If the runner is short, the reflected pulse might fall out of the end before the valve opens to suck it back in. If the runner is too long, the larger mass of air may react too slowly to perform well at high engine speeds.
