<<See All OBD Codes

The error code P0665 can be identified as Intake Manifold Tuning Valve Control Circuit High Bank 2. This trouble code indicates that there is an electrical fault with the intake manifold tuning valve control circuit in engine bank 2.

Want to learn something more about this fault code? This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another.

This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

What causes this problem with the Intake Manifold Tuning Valve Control Circuit High Bank 2?

• Valve parts might be broken
• Malfunction in the engine control module
• Valve might start contaminating
• 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
• Wiring issue like chafed, cracked, corroded, etc
• Electrical connector might be broken

1. Body Control Module - The P0665 code can also arise due to some issues in Body Control Module. So, it is advised to replace them as soon as possible.
2. Engine Control Module - Do you remember when was the last time you got your car engine control module checked up? A damaged engine control module can cause a lot of issues like displaying P0665 code.
3. Idle Air Control Valve - Idle Air Control Valve is an important car part which should never be neglected. May be there is some fault in it due to which P0665 code may start flashing.
4. Powertrain Control Module - Is your Powertrain Control Module damaged or broken? Don’t worry as we have solutions for all your problems.
5. Intake Manifold Gasket Set - Defective car Intake Manifold Gasket Set can be a major reason why P0665 code depicts. So, make sure to replace it online so that you don’t have to face any further issues.
6. Intake Manifold Actuator - Everything is okay with the Intake Manifold Gasket Set and still OBD code P0665 triggering? Then there must be some defects in Intake Manifold Actuator. Replace them as soon as possible.
7. Electronic Control Unit - P0665 code flashing? Get your Electronic Control Unit inspected from a mechanic.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• CAN stands for controller area network. The CAN represents a communication bus that allows multiple microcontrollers to communicate with one another without the need for a host computer
• It is a message-based protocol originally designed for automotive use. The CAN bus network is actually a complex conglomeration of wiring harnesses and connectors used as a pipeline of information shared between two or more automotive control modules
• The cruise control module uses the data for speed control purposes, the traction control system uses the data to regulate vehicle traction control strategy, and the anti-lock brake controller compares vehicle speed from the PCM with data inputs from individual wheel speed sensors to operate the anti-lock braking system
• Several tools will be instrumental in attempting to successfully diagnose this code. A suitable OBD-II scanner (or code reader) and a digital volt/ohmmeter will be most helpful in trying to perform a successful diagnosis
• You must start with a visual inspection of all wiring and connectors. Repair or replace damaged, disconnected, shorted, or corroded wiring, connectors, and components as necessary
• Retest the system after repairs are completed to ensure success
• If all system wiring, connectors, and components appear to be in normal working order, connect the scanner to the diagnostic connector and record all stored codes and freeze frame data
• Continue by clearing the code and operating the vehicle to see if it returns
• This will help to determine whether or not the malfunction is intermittent. After the codes are cleared, test drive the vehicle to see if the code returns
• If the code fails to immediately return, you may have an intermittent condition
• Intermittent conditions can prove to be quite a challenge to diagnose and in extreme cases may have to be allowed to worsen before a correct diagnosis can even be attempted
• 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
• Compare your findings with the manufacturer’s referenced values and repair open or shorted circuits as required
• It is often much more frugal to replace defective wiring rather than attempting to remove it from the complex web of wiring harnesses

Common Mistakes When Diagnosing the P0665 Code

• One of the most common mistakes which is made when diagnosing this code comes from a failure to follow the OBD-II diagnosis protocol
• The mechanic should follow the protocol step by step and should make repairs accurately
