P0664 is the trouble code identified as "Intake Manifold Tuning Valve Control Circuit Low Bank 2" and this indicates that the ECM has detected too low of electrical reading from the valve on bank #2. Bank #2 is the side of the engine that does not contain cylinder #1.

Sep 16, 2024 · This code indicates that there is a problem with the control circuit for the intake manifold tuning valve on the second bank of the engine. The intake manifold tuning valve is responsible for adjusting the length of the intake manifold runners to optimize airflow and improve engine performance at different RPM ranges.

Code P0664 is a manufacturer-specific OBD-II code that relates to a problem with the intake manifold tuning valve control circuit on bank 2. A car’s intake manifold is responsible for regulating the airflow into the engine. It directs air into the combustion chamber, where it is mixed with fuel to create the explosion that drives the engine.

Aug 16, 2024 · The P0664 fault-error code indicates a problem with the vehicle's intake manifold tuning valve control circuit. This code is detected and stored by the vehicle's OBD-II (On-Board Diagnostics II) system.

Feb 16, 2025 · What does the P0664 code mean? The P0664 code signifies a problem with the intake manifold tuning valve control circuit on bank 2 of your engine. This particular system plays a crucial role in optimizing airflow for better performance and fuel efficiency.

Jul 26, 2017 · P0664故障码，适用于所有汽车制造商，意思是进气歧管调谐阀控制电路低（第2排） (Intake Manifold Tuning Valve Control Circuit Low (Bank 2))。 提示：快速查找故障码，可以关注“ 车主指南 ”公众号，回复故障代码，如：“ P0664 ”，即可获得对应故障码解释和解决方案。 背景知识：如果进气歧管通路（runner）的长度最佳，气门关闭所产生的压力波会帮助将油气混合物导入发动机。 问题是发动机不同转速对应的最佳进气歧管通路长度也不同。 歧管调谐 …

p0664 故障码，作为通用代码，适用于各类汽车品牌，其含义为“进气歧管调谐阀控制电路低（第2排）”。 这一代码的出现，通常意味着车辆的电子控制单元（ECU）在自检过程中，检测到进气歧管调谐阀控制电路的电压低于预设的最低值。

P0664 is the trouble code identified as “Intake Manifold Tuning Valve Control Circuit Low Bank 2,” indicating that the ECM has detected an electrical reading that is too low from the valve on bank #2. Bank #2 refers to the side of the engine that does not contain cylinder #1.

故障代码：p0664中文含义：进气歧管调谐阀控制电路低(第2排)英文含义：进气歧管调谐阀控制电路低(第2排)类别：计算机或辅助输出电路。 详细含义：如果进气歧管流道长度最佳，气门关闭产生的压力波有助于将油气混合气引入发动机。

故障代码p0664详细描述如下:故障的系统范围:计算机或辅助输出电路适用车型:所有汽车制造商。 中文含义解释:进气歧管调节器(第2组)控制电路电压低英文含义:目前不了解P0664故障码:1。
