If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2004 fault code. This code indicates a problem with the Intake Manifold Runner Control (IMRC) actuator, which controls the airflow into the engine. The cause could be a faulty IMRC actuator, open or shorted actuator harness, poor electrical connection, or a faulty Powertrain Control Module (PCM).

It is important to address this issue promptly as it can affect the engine’s performance and fuel efficiency. The repair time for this fault code is estimated at 1.0.

To fix the issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2004 fault code.

Here are the symptoms to look out for:

  • The P2004 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, rough idling, stalling, and decreased fuel efficiency.
  • Additionally, the vehicle may experience a loss of acceleration or have difficulty starting.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

P2004 fault code can be caused by a faulty IMRC actuator, open circuit, poor connection, or a faulty PCM.

  • The automobile fault code P2004 can be caused by a faulty Intake Manifold Runner Control (IMRC) actuator.
  • It can also be caused by an open or shorted Intake Manifold Runner Control actuator harness.
  • Another cause can be a poor electrical connection in the Intake Manifold Runner Control actuator circuit.
  • Lastly, a faulty Powertrain Control Module (PCM) can also cause the P2004 fault code.

To fix the p2004 automobile fault code, check the possible causes and inspect related wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code P2004, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • Ensure that all the connections are secure and tight.
  • This repair should take approximately 1.0 hour.

The fault code P2004 indicates a problem with the intake manifold runner control system.

The diagnosis process involves checking the vacuum lines, electrical connections, and the control solenoid.

The fixing cost for this fault code is influenced by the estimated repair time, which is typically 1.0 hour.

Most auto repair shops charge between $75 and $150 per hour, which means the fixing cost can range from $75 to $150. Other factors that may affect the fixing cost include the severity of the problem, the type of vehicle, and the location of the repair shop.

The P2004 code refers to the Intake Manifold Runner Control (IMRC) system.

The IMRC system consists of a motorized actuator with an attaching linkage for each housing on each bank. The IMRC housing is an aluminum casting with two intake air passages for each cylinder.

The P2004 code sets when the IMRC is commanded close, but the IMRC monitor indicates open.

This code indicates that the IMRC is stuck open on Bank 1.

What are the possible causes of the P2004 fault code?

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2004 fault code. This code is caused by a faulty Intake Manifold Runner Control (IMRC) actuator, an open or shorted IMRC actuator harness, a poor electrical connection in the IMRC actuator circuit, or a faulty Powertrain Control Module (PCM). To fix this issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector’s pins.
