What does intake manifold runner control stuck open bank 1 mean?

What does intake manifold runner control stuck open bank 1 mean?

The P2004 diagnostic trouble code indicates that the intake manifold runner control (IMRC) is stuck in the open position on Bank 1. By regulating intake airflow, harmful emissions are reduced, the air/fuel mixture is improved, and fuel economy is increased. The components of the IMRC include: vacuum actuator.

What is a P200A code?

OBD-II Code P200A is defined as a Intake Manifold Runner Performance. The Intake Manifold Runner allows more air to flow through the intake at higher RPMs. If the Intake Manifold Runner does not operate as requested, P200A will be set.

How do I fix code P200A?

Have a look at some ways with which you can correct the P200A code:

1. Repair or replace a damaged intake manifold runner.
2. Measures should be taken to fix an open or shorted harness in the manifold flow valve.
3. A defective manifold flow valve should be repaired or changed.

What is a VCM actuator?

The VCM system tumbles air flow entering into combustion chamber of each cylinder by closing the VCM valve in the cold start conditions. This tumble effect reduces cold start emissions by improving atomization.

What does a VCM motor do?

Variable Cylinder Management (VCM) is Honda’s term for its variable displacement technology, which saves fuel by using the i-VTEC system to disable one bank of cylinders during specific driving conditions—for example, highway driving.

What does a variable charge motor do?

A variable intake can create two or more pressurized “hot spots”, increasing engine output. When the intake air speed is higher, the dynamic pressure pushing the air (and/or mixture) inside the engine is increased.

Why does VCM burn oil?

The VCM System in More Detail It allows the engine to disable half of the cylinders when the engine’s full power is not needed. The frequent shutting off and turning on of the cylinders made the cylinders prone to rotation, allowing the ring gaps to align and causing the oil to leak into the combustion chamber.

Can you disable Honda VCM?

The operating temperature of the vehicle is unchanged and all data is within OBD-II limits as normal operation for the vehicle when properly installed and setup according to the users manual,, Honda does not officially endorse any method to disable VCM at this time.
