It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0661 code to be stored:

• You must firstly use an OBD-II scanner to check for a stored P0661 trouble code
• After that the mechanic should note down the codes and then clear them
• Then the vehicle should be taken out for a test drive
• The mechanic will also need to visually inspect all the wiring and connectors in the intake manifold tuning valve control circuit for opens, shorts, corrosion or other damage
• Keep this thing in mind that damage to the wiring harness or a loose/poor connection are some of the most common faults in this case
• An advanced scanner should be used by a mechanic to determine the general area of the problem, rather than testing each individually.
• In addition, it may be necessary to have a CAN scanner to rule out faults in the CAN bus
• The mechanic should also test the PCM, as failed drivers are one of the more common causes of the P0661 code
• The intake manifold tuning valve will also need to be tested for operation. Once the underlying problem has been diagnosed and repaired, the vehicle must be test driven again for drivability and to determine proper operation
• Compare your findings with the manufacturer’s referenced values and repair open or shorted circuits as per the requirement

Common Mistakes When Diagnosing the P0661 Code

• Most common mistake here is attempting to repair the condition by addressing related symptom codes
• The mechanics think that a misfire code is the real problem and trying to repair it would not solve the issue
• If you want to diagnose this trouble code, then you should start with the earliest code and work forward to the most recent
