What is an Imrc actuator?

What is an Imrc actuator?

The Intake Manifold Runner Control (IMRC) is an electrically actuated system consisting of a motorized actuator with an attaching linkage for each housing on each bank. The motorized actuator houses internal switches to provide feedback to the powertrain control module (PCM), indicating linkage and plate position.

How do I fix code P2007?

How To Correct P2007 Intake Manifold Runner Control Stuck Closed Bank 2 Issue

1. The malfunctioning PCM should be repaired or replaced as per the need.
2. Carefully adjust the faults in the Intake manifold runner bank 2.
3. The Wiring harness should be restored to working order.

What does the Imrc solenoid do?

The term usually refers to the IMRC actuator, but some vehicle manufacturers may use the phrase to describe the solenoid instead. Basically, the IMRC valve is the part of the system that opens and closes the flaps inside the intake manifold.

What does a Imrc solenoid do?

The intake manifold runner control (IMRC) system is responsible for tuning the airflow inside the intake manifold before that air enters the engine. The IMRC system features a solenoid that opens and closes the flaps inside the intake manifold.

What is code P2007?

The P2007 code means the intake manifold runner is stuck closed for bank 2. The ECU controls how much to open or close the intake manifold runner flaps and when bank 2 is stuck open the P2007 code is set. This triggers a Check Engine Light to be displayed on the dashboard and a failsafe mode to be enabled.

What does IMRC mean on a 2004 Ford Explorer?

P2004 FORD Meaning The Intake Manifold Runner Control (IMRC) is an electrically actuated system consisting of a motorized actuator with an attaching linkage for each housing on each bank. The linkage attaches to the housing butterfly plate levers. Each IMRC housing is an aluminum casting with two intake air passages for each cylinder.

Where to run the IMRC actuator and CHT sensor?

The wiring harness to the IMRC actuator and the CHT sensor have to be routed between the IMRC linkage and the Intake Manifold. It appears OTHERWISE during reinstallation of the IM. But if they are ran behind the linkage, they will ‘rub’.

How does an IMRC housing work?

Each IMRC housing is an aluminum casting with two intake air passages for each cylinder. One passage is always open, and the other is opened and closed with a butterfly valve plate. The housing uses a return spring to hold the plates closed.

What PID does the PCM open the actuator?

I learned: The PCM ‘commands’ it open (Indicated by PID 1103, bit 4=true). Positional feedback from actuator is at PID 1634. (screwy ‘upside-down’ formula), -128 = closed, Formula for Degrees open from 0 to 90 is: INT (50.4+ ( (100/255)*Signed (A)+Signed (B)))).
