What does the Imrc valve do?
The intake manifold runner control system improves the engine airflow process, which helps performance and efficiency. Although each carmaker’s design is different, the basic concept involves opening and closing butterfly valves within the intake manifold. The valves divert airflow, changing the length of the runners.
Where is the intake manifold control valve 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].
What is p1077 Honda CRV?
The p1077 code for Honda CR-V indicates that the intake manifold runner control system (IMRC) is at a low rpm and has malfunctioned. The IMRC controls the opening and closing of butterfly valves inside of the intake manifold runners.
What is a Imrc?
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. Each IMRC housing is an aluminum casting with two intake air passages for each cylinder.
What is a Imrc delete?
The second generation (2015-2017) and third generation (2018+) CMCV/IMRC delete lock outs allow you to remove the bulky factory vacuum pods and pin the intake manifold doors up for maximum airflow at all engine speeds. If you are using a power adder, this is a must.

What is intake manifold runner control stuck open?
The intake manifold is the part of the engine that supplies the cylinder head with the mixture of fuel and air. 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.
What is a manifold tuning valve?
The intake manifold tuning valve comes with many possible purposes to help the engine in both performance and drivability. It regulates the pressure between intake plenums, or redirect intake air to separate set of intake runners (or combination) to change the flow and possibly the performance of the engine.
What is code p1457 on Honda CRV?
This is a trouble code for a leak in the evaporative (EVAP) system, the charcoal canister side of the system. Potential Causes: Restricted purge line, evaporative canister vent shut valve, bypass solenoid/two-way valve, purge solenoid and/or a leaking canister or evaporative hose.
What is P1166 code mean?
Error Code P1166 is described as Air/Fuel Ratio Sensor 1 Heater Circuit Malfunction. This means a malfunction is detected in the Air/Fuel (A/F) ratio sensor stemming from an incorrect voltage value registered when the power was drawn to the sensor.
How to repair the IMRC solenoid valve No.4?
If the fuse OK, repair open in the wire between the IMRC solenoid valve and No. 4 ACG (10A) fuse. Turn the ignition switch OFF. Disconnect the negative cable from the battery. Disconnect ECM/PCM connector B (24P). Connect IMRC solenoid valve 2P connector terminal No. 2 to body ground with a jumper wire.
Can a vacuum leak be repaired with an IMRC valve?
No : Repair the blockage or vacuum leak between the intake manifold and IMRC solenoid valve. Reconnect the lower vacuum hose to the IMRC solenoid valve, and connect the vacuum pump/gauge to the vacuum hose (actuator side).
How to troubleshoot the IMRC system cont.11-178?
IMRC System Troubleshooting (cont’d) 11-178 1 Turn the ignition switch OFF. 2 Disconnect the negative cable from the battery. 3 Disconnect ECM/PCM connector B (24P). 4 Check for continuity between IMRC solenoid valve 2P connector terminal No. 2 and body ground. More
