Error Code P0660: What It Means & What To Do?

<<See All OBD Codes

The error code P0660 can be defined as Intake Manifold Tuning Valve Control Circuit/Open Bank 1 Issue. This trouble code would start indicating that there is an issue with the bank 1 of the engine intake manifold tuning valve control circuit, which is generally caused because of faulty wires or quirky PCM.

P0660 trouble code would start appearing if powertrain control module would detect an error in the intake manifold control circuit for engine bank 1. This error code can also be detected by body control module, turbo control module, instrument panel control module, anti-theft module, transmission control module, anti-lock brake control module, traction control module, cruise control module, climate control module, and proximity alert module.

What causes this problem with the Intake Manifold Tuning Valve Control Circuit/Open

Bank 1?

• Some problems related to the stuck valve
• Defaults in the fuel injector control module
• There can be some faults in the intake manifold tuning valve
• Valve parts might be broken
• Wiring issue like chafed, cracked, corroded, etc
• Valve might start contaminating
• Electrical connector might be broken
• Malfunction in the engine control module

• Decline in the engine power
• Diminishing engine performance or acceleration
• Less fuel economy
• Noise coming from engine bay can be very loud
• Power range altered
• Engine might start stalling
• There can be a possible misfire on start-up

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P0660:

• Make sure to replace the CAN bus
• You can always replace the powertrain control module if found defective
• If you find out that there is some fault in the wiring, connectors, and modules then they should be repaired or replaced properly

Here are some steps which you should follow in order to diagnose this fault code:

• If you want to perform successful diagnosis for the P0660 trouble code, then you will need an OBD-II scanner and a digital volt/ohmmeter.
• Start the visual inspection of all wiring and connectors
• You should repair or replace damaged, disconnected, shorted, or corroded wiring, connectors, and components as per the requirement
• If you want to ensure success, then it is important to retest the entire system once the repairs have been done
• Now if all the system wiring, connectors, and components appear to be in good working condition, then you should connect the scanner to the diagnostic connector
• Record all the stored codes as well as freeze frame data
• This information can be extremely helpful in diagnosing intermittent conditions that may have contributed to this code being stored.
• You should continue by clearing the code and operating the vehicle to see if it returns
• This would be very helpful in determining whether or not the malfunction is intermittent
• After the codes are cleared, you should test drive the vehicle to see if the code returns
• If the code fails to immediately return, you may have an intermittent condition
• Keep this thing in mind that intermittent conditions can be quite challenging to diagnose and in extreme cases may have to be allowed to worsen before a correct diagnosis can even be attempted.
• A specialized diagnostic CAN scanner will show pin values and control module operation without risking a meltdown. It can accurately diagnose computer and circuitry problems by monitoring vehicle operation while the vehicle is being operated. To diagnose this type of code using a digital volt ohmmeter would entail probing thousands of circuits, independently
• An auxiliary ground cable can be helpful in diagnosing system ground discrepancies. Engine and transmission ground cables, straps, and wires are sometimes left dangling after repairs are performed
• Look for loose or corroded electrical connectors that may increase circuit resistance and cause these types of codes to be stored. Obtain a CAN bus system wiring diagram and/or pin out value chart, then use the digital volt ohmmeter to test continuity between individual controller connectors
• Make sure to compare your findings with the manufacturer’s referenced values and repair open or shorted circuits as per the need

Common Mistakes When Diagnosing The P0660 Code

• Practically any code that is stored in response to an engine misfire, fuel injector issue or lean exhaust can be easily misdiagnosed,
• The repair of this trouble code would not be successful if some wrong parts are replaced
• It is very important to diagnose the trouble code in the order in which it is stored or else the diagnosis would be unsuccessful
