What is the P0660 fault number? What is the description for the Intake Manifold Regulator Valve Control Circuit/Open (Bank 1) malfunction? How do I fix the P0660 fault code What are the causes and symptoms of the P0660 fault codes?
What is the P0660 fault code? What does it signify?
The intake manifold regulating vale is an integral component of the intake manifold. It serves multiple purposes to ensure the engine runs smoothly. It is responsible for opening and closing vanes in intake manifold. It regulates pressure between intake plenums. Also, it directs air to correct intake ducts. It is made from plastic so it can crack if exposed to high temperatures. The valve might also not function properly if it is located in extremely cold areas.
If the powertrain control module, PCM detects an open circuit (disconnected wires or connectors) within the intake manifold regulator valve circuit, a code P0660 will be set. In the code’s definition, “Bank 1” refers to the engine bank that contains the engine’s #1 Cylinder.
The P0660 fault code can affect vehicles of all makes and models, including but not limited to: Opel, Mercedes Benz, Nissan. Opel, Dodge, Mitsubishi. Mazda. Chrysler. Vauxhall. Chevrolet. Saturn. Land Rover. Porsche.
What is the P0660 Fault Code?
Here are some reasons why P0660 should be set.
- – Sticky or defective intake manifold regulator valve
- – Defective valve components
- Damaged wires and/or connections to the intake manifold regulator valve leading to an open circuit
- – Damaged wires and connectors in the harness for the CAN bus
- – Extremely cold climate conditions
What are the symptoms of the P0660 fault code?
You may experience the following symptoms if your vehicle has the code P0660:
- – Illumination and control of the check engine light
- – Reduced engine performance, particularly at low revs
- – Increased fuel use
- – Engine misfires at idle
- – Fluctuations at idle speed
- – Cold engine difficult to start
- Loud clicking noises coming from the engine compartment
How to Fix the P0660 Fault Code
This issue is often related to issues with CAN (controller-area network bus), which allows communication between multiple microcontrollers on the vehicle. It regulates most electrical functions. The master controller is the PCM. Sometimes controllers can fail. The mechanic will inspect each module and replace any that are defective.
The following repairs may be able to resolve the P0660 fault code:
- – Replacing an inoperative intake manifold regulating Val
- – Repairing damaged cables or connectors that are causing an open circuit
- – Replace the CAN bus if necessary
- – Replacement of defective modules and PCM
How serious is the P0660 fault code?
The engine should not stall if fault code P0660 is displayed. This is a serious safety problem that could endanger you, other passengers or drivers. Even if there is only an increase in fuel consumption, it could get worse over time so fix it as soon as you can.
