What is a intake manifold runner position sensor?

What is a intake manifold runner position sensor?

The runner position sensor, also known as the runner valve, controls the volume of air entering the intake manifold. The runner valve controls a flap in the intake manifold, which will open or close depending on the air requirements of the engine. It is designed to help optimize the air-fuel ratio (AFR) of the engine.

What does the intake manifold runner control valve do?

The intake manifold runner control is an engine management component that is found on newer intake manifold designs. It is usually a motorized or vacuum actuated unit attached to the intake manifold, that controls the opening and closing of butterfly valves inside of the intake manifold runners.

What is an intake actuator?

The Intake Manifold Actuator is mounted on an Intake Manifold that acts as a passage of air that is sucked into the cylinder of the engine.

What does a bad manifold sound like?

In many cases a cracked manifold will create a hissing or tapping sound coming from the engine bay. This sound could be loudest or most pronounced at a cold start. This is because as the gasket heats up, it expands and could seal the leak better.

How much does it cost to diagnose Honda code p0661?

The cost to diagnose the P0661 HONDA code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour. | When is the code detected?

What does the p0661 code on the IMRC mean?

If the output voltage from the Intake Manifold Runner Control (IMRC) valve position sensor is lower than a set value, a malfunction is detected and the P0661 code will set. Engine power is achieved by closing and opening the Intake Manifold Runner Control (IMRC) valve.

What does trouble code p0661 mean on an intake manifold?

P0661 is the trouble code identified as “Intake Manifold Tuning Valve Control Circuit Low Bank 1” and this indicates that the ECM has detected too low of electrical reading from the valve on bank #1.
