P0660 is a diagnostic trouble code (DTC) for “Intake Manifold Tuning Valve Control Circuit/Open Bank 1“. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What is code P0660?
P0660 Code: Intake Manifold Tuning Valve Control Circuit Open / Open Bank 1.
What is the intake manifold tuning valve?
An actuator for an intake manifold tuning valve to regulate airflow in an intake manifold of an internal combustion engine. The actuator includes a motor, control circuit, and sensor all mounted in a housing that has an opening through which an output shaft extends.
How do I fix code P0661?
What repairs can fix the P0661 code?
- Reinstalling the driver in the PCM.
- Replacing a failed intake manifold tuning valve.
- Repairing loose or corroded connections in the wiring for the intake manifold tuning valve.
What does P0661 code mean?
Intake Manifold Tuning Valve Control Circuit Low
OBD-II Code P0661 is defined as a Intake Manifold Tuning Valve Control Circuit Low. The Intake Manifold Tuning Valve allows additional air to flow through the intake at higher RPMs. If the engine computer (PCM) detects that the Intake Manifold Tuning Valve is not operating as requested, code P0661 will be set.
How much does it cost to replace a intake manifold runner control?
A new intake manifold runner valve can cost anywhere between $50 and $200, depending on factors like its brand and your vehicle’s specifications. Labor costs for replacing a damaged intake manifold runner valve typically range from $300 to $400.
What is a swirl control valve?
The solenoid valve controls swirl control valve’s shut/open condition. This solenoid valve is operated by the ECM. This is correct. The primary purpose of the swirl valve is to promote complete vaporization of the fuel in the combustion chamber at slow engine speeds.
What can a bad intake manifold runner control cause?
If the intake manifold runner control has an issue it can cause the vehicle to experience engine performance issues such as misfires, a decrease in power and acceleration, a decrease in fuel efficiency, and even stalling.
Where is the intake manifold runner control located?
Above and behind the serpentine belt, you’ll find a black box with linkages coming out of it. The box contains an electric motor that controls two doors or flaps in the side of the intake manifold [Ford calls it the Intake Manifold Runner Control].
How much does it cost to replace the intake manifold?
In general, though, gasket replacement costs average around $350, having a mechanic replace your 5.3-liter intake manifold gasket. This cost can vary from $200 to $500 based on your vehicle, the mechanic, and location.
What is an IMT valve?
The IMT valve helps increase engine torque by changing the length of the runner in the intake manifold to match the conditions in which the vehicle is being driven. When the tuning valve gets stuck open, it is possible that the engine may not perform optimally.
