What the P2004 code means

The P2004 diagnostic problem code indicates that the entry manifold runner control (IMRC) is stuck in the open position on bank 1.

The Powertrain manage Module (PCM) offers the IMRC with details relating to present driving conditions, and also the IMRC uses this information to manage the amount of airflow that is permitted into the input system. By regulation intake airflow, harmful emissions space reduced, the air/fuel mixture is improved, and fuel economy is increased.

The components of the IMRC include:

vacuum actuator electrical solenoidbutterfly valve platesair passageways to each cylinderlinkage rods linked to the input manifold butterfly plate levelreturn springs that organize the butterfly valve plates open

The PCM receives info from the IMRC solenoid, mass airflow (MAF) sensor, and also barometric (BARO) sensor to make a determination as to the suitable position of the IMRC butterfly valve plates. The plates then open and also close to enable or restrict air from entering into the entry system.

At high speeds/RPM, the IMRC butterfly valve key will open to allow the circulation of air into the intake system, and at low speeds/RPM, the IMRC butterfly valve plates will close to restrict the circulation of air into the intake system. If the PCM determines the voltage reading from the IMRC solenoid, MAF sensor, and BARO sensor suggest that the IMRC butterfly valve plates space not in the proper position, the will keep the P2004 problem code.

What reasons the P2004 code?

IMRC solenoid the is defectiveIMRC solenoid wiring that has actually shorts, breaks, or is frayed.IMRC solenoid circuitry that has shorted or is openIMRC solenoid connector that is corrodedIMRC butterfly valve plate screws the are loose or brokenIMRC butterfly valve key that room brokenIMRC butterfly valves key that have disconnected native the IMRC actuatorVacuum control solenoid vacuum filter the is cloggedDebris in the vacuum manage solenoidVacuum currently that room disconnected or brokenCarbon buildup top top the IMRC butterfly valve platesExhaust gas recirculation (EGR) valve problem codes that have actually been save by the PCMMAF sensor problem codes that have been stored by the PCMBARO sensor problem codes that have been save by the PCM

What space the symptom of the P2004 code?

Decrease in fuel economyDecrease in low end engine torqueThe engine may surge/sputterThe auto will run roughCheck Engine/Service Engine soon Light onCheck Engine/Service Engine quickly Light flashing

How go a mechanic diagnose the P2004 code?

Uses an OBD-II scanner to collection freeze framework data and any trouble codes that have been stored by the PCM (if problem codes because that the EGR valve, MAF sensor, and/or BARO sensor have been save by the PCM, they must be diagnosed and also repaired first)Completes a intuitive inspection of every wiring for shorts, breaks, and fraysRepairs or replaces any shorted, frayed, or broken wiringCompletes a intuitive inspection that the IMRC solenoid because that corrosion and damageRepairs or replaces any kind of corroded or damaged connectorsInspects the vacuum lines and also hosesRepairs or replace instead instead any loose or damaged vacuum currently or hoses Inspects the IMRC butterfly valve bowl for appropriate connection and/or breaksInspects the EGR valve for excessive carbon buildup (this carbon buildup can get ~ above the IMRC solenoid and render it defective)Clears the codes and also retests to view if the P2004 trouble code returnsUses the scan device to test the IMRC solenoid:

Open and also close the IMRC solenoid utilizing the scanner. If the IMRC solenoid does not respond, the solenoid will should be replaced.

Common mistakes as soon as diagnosing the P2004 code

Misdiagnosing and also replacing the IMRC solenoidMisdiagnosing and also replacing the IMRC butterfly valve platesOverlooking damaged or disconnected vacuum linesOverlooking IMRC solenoid connector and also wiringReplacing the IMRC butterfly valve plates when the difficulty was the they to be not linked properlyNeglecting to diagnose and also repair various other EGR valve, MAF sensor, and/or BARO trouble codes before making any repairs because that the P2004 problem code.

How serious is the P2004 code?

The P2004 trouble password may end up being serious if the hardware because that the IMRC butterfly valve plates become loose and loss off into the engine. If this happens, major engine damage is possible, and could potentially reason engine failure. That is necessary to have the P2004 trouble code inspected and also repaired as quickly as possible.

What repairs deserve to fix the P2004 code?

Replacing the IMRC solenoidRepairing or instead of IMRC solenoid wiring that has actually shorts, breaks or is frayedRepairing or replacing IMRC solenoid circuitry that has shorted or is openRepairing or instead of IMRC solenoid connector that is corroded.Repairing and/or instead of IMRC butterfly valve plate hardware, if necessaryRepairing or replacing loose or damaged vacuum linesReplacing IMRC butterfly valve key (in order to execute this, the entry manifold assembly will have to be replaced)Diagnosing and also repairing EGR valve, MAF sensor, and/or BARO problem codes, if present

Additional comments because that consideration regarding the P2004 code

The PCM may store the P2004 trouble code if the IMRC butterfly valve plates end up being detached from the IMRC actuator. This code may be resolved quickly by checking the connection of the IMRC butterfly valve plates and the IMRC actuator.

It is likewise common because that the PCM to save the P2004 problem code due to the fact that carbon buildup in the entry is causing the IMRC butterfly valve bowl to come to be stuck.
