What does that mean?
P0660 stands for “Intake Manifold Tuning Valve Control Circuit/Open Bank 1” and indicates that the ECM has detected a general electrical fault or an open electrical situation. This code can be triggered by a mechanical or electrical fault with the intake manifold tuning valve.
What is the severity of this DTC?
It’s a good idea to err on the side of caution when dealing with mechanical parts like the intake manifold tuning valve, especially if it’s an internal part, because the potential for unwanted parts to enter the engine’s combustion chamber exists.
What are some of the symptoms of the code?
Poor engine performance. Loud clicking noise coming from engine bay. Reduced fuel economy. Possible misfire on startup. Reduced engine power. Power range altered are all signs of a P0660 diagnostic code.
What are some of the common causes of the code?
Defective intake manifold (runner) tuning valve. Broken valve parts. Wiring issue (e.g. chafed, cracked, corroded, etc.). Broken electrical connector ECM issue are all possible causes for the P0660 engine code.
What are some P0660 diagnostic and troubleshooting steps?
Diagnostic diagnostic steps are vehicle specific and may require advanced equipment and knowledge to perform accurately. We have included basic steps below, but for specific steps for your vehicle, refer to a vehicle year/make/model/powertrain specific repair guide. The TSB Technical Service Bulletins (TSB) for known issues with the specific vehicle.
Basic Step #1
When the ECM activates a DTC (diagnostic trouble code), it’s a good idea for a DIYer to clear all of the codes; if not, take the vehicle for a long and numerous test drive to see if it/they become active again after a few duty cycles.
Basic Step #3
If you hear clicking noises coming from your intake, this is a good way to see if the intake manifold tuning valve is to blame. If there are no obstructions and the clicking continues, you should replace the valve, as this is most likely the problem.
Basic Step #4
Wiring harnesses can be routed through engine parts and other high-heat areas, so inspect the harness involved with the tuning valve. Engine vibrations can cause chafing/cracking, so keep an eye on them.
Basic Step #5
If you’ve exhausted all other options, check your ECM (Engine Control Module) to see if multiple unrelated codes are currently active or intermittently coming on and off, such as P0303 Cylinder 3 Misfire on a Chrysler 2007 Pacifica P0203 P0660.
How do I fix code P0660?
Bad wiring, connectors, and modules can be repaired or replaced, as can the CAN bus, and if the PCM itself is faulty, it can be replaced.
What is po660?
Intake Manifold Tuning Valve Control Circuit/Open Bank 1 is Error Code P0660, which indicates a problem with the bank 1 of the engine’s intake manifold turning valve control circuit, which is typically caused by damaged wires or a faulty PCM.
What is a intake manifold tuning valve control circuit?
The intake manifold tuning valve serves a variety of functions to aid the engine’s performance and drivability, including regulating the pressure between intake plenums and redirecting intake air to a different set of intake runners (or a combination) to alter the flow and possibly the engine’s performance.
What is engine code P1005?
The P1005 Chrysler code indicates a communication error between the ECU (your car’s onboard computer) and the Manifold Tuning Valve on the intake manifold; if the Manifold Tuning Valve is not replaced, you risk serious engine problems throughout the year.
What can a bad intake manifold runner control cause?
If the intake manifold runner control fails, the vehicle may experience engine performance issues such as misfires, reduced power and acceleration, reduced fuel efficiency, and even stalling.
How does intake manifold runner control work?
Although each carmaker’s design differs, the basic concept entails opening and closing butterfly valves within the intake manifold, which divert airflow and change the length of the runners.
How much does it cost to replace a intake manifold runner control?
How much does it cost to replace an intake manifold runner control? Find out how much it should cost to get your car fixed. The average cost of an intake manifold gasket replacement is between $427 and $558, with labor costs ranging from $334 to $423 and parts costs ranging from $93 to $135.
What is a intake manifold changeover valve?
Internally, at 3700 RPM, the intake manifold switchover (or changeover) valve switches the intake manifold from very long runners for low end torque to shorter runners for high end power.
