Details of the Honda p0661 OBD Code
Code P0661 in Honda indicates a fault with the intake manifold tuning valve control circuit.
Code P0661 for Honda vehicles indicates a problem with the intake manifold tuning valve control circuit low voltage.
This code is triggered by the Engine Control Module (ECM) when it detects a lower than expected voltage signal from the intake manifold tuning valve control circuit.
The intake manifold tuning valve is responsible for adjusting the length of the intake manifold runners to optimize engine performance at different RPM ranges.
When the ECM detects a low voltage signal from this circuit, it illuminates the Check Engine Light and stores the P0661 trouble code.
