What is P0661 fault code and what does it mean? What is the description of Intake Manifold RegulatorValve Control Circuit Lower (Bank 1)? How can I fix the P0661 fault? What are the causes and symptoms of the P0661 fault codes?
What is the P0661 fault code? What does it signify?
A code P0661 is an indication of what it means “Intake Manifold Valve Control Circuit Low Bank 1” . If the powertrain controller module (PCM), detects an issue with the intake manifold regulation valve, or a voltage signal that is lower than manufacturer’s requirements, P0661 is generated. “Bank 1” On V6-V8 engine, this refers to the engine bank containing engine’s #1cylinder.
The intake manifold tuning valle serves multiple purposes. It can improve the engine’s performance and driveability. One purpose is to regulate pressure between the suction and exhaust plenums. The second is to direct air from the engine to the right channels so that it runs at maximum performance. The valve is typically made from plastic so it can crack if exposed to high temperatures. If you live in extremely cold regions, the valve could get stuck and stop working properly.
P0661 fault codes can be found on vehicles made by Acura, Acura, Isuzu Honda Hyundai Jaguar, Jeep, Ford and many other manufacturers.
What causes the P0661 Fault code?
Below are some reasons to set fault code P0661:
- – Bad, stuck or dirty intake manifold regulating Valve
- – Damaged wiring, loose or rusty connectors that cause an open or closed circuit in the intake valve control circuit.
- – Defective or broken valve components
- – Extremely cold climate conditions
- PCM related issues
What are the symptoms of P0661 Malfunction code?
You may experience the following symptoms if your vehicle has the code P0661:
- – Illumination at the check engine lights
- – Engine stalling
- – Engine misfires and fluctuations in engine speed at idle
- – Cold engine difficulty
- – Significant decrease in engine performance
- – Noticeable power loss, especially during acceleration
- – Increased fuel consumption
- – Engine compartment clicking noises
How to Fix the P0661 Fault Code
The following repairs may be able to resolve the P0661 fault codes:
- – Repairing or cleaning a damaged intake manifold regulating device
- Repair of damaged cables or connectors that are causing open or short circuits
- – Clean the manifold and check for a blockage
- – Reprogramming your PCM
How serious is the P0661 Fault code?
While the P0661 fault code doesn’t prevent you from using your vehicle it can cause engine damage, increased fuel consumption, and misfire problems later on. Unexpectedly, an engine can stall or lose performance. This could pose serious safety risks. This code should not be ignored and must be addressed as soon as possible.
