P0663 - OBD Trouble Code

<<See All OBD Codes

The error code P0663 can be defined as Intake Manifold Tuning Valve Control Circuit/Open Bank 2. This trouble code would start appearing when a fault has been detected by the Powertrain Control Module (PCM) in the intake manifold tuning valve control circuit.

Do you want to gain some more knowledge about the P0663 trouble code? The Powertrain Control Module (PCM) continuously monitor the Intake Manifold Tuning Valve (IMTV) system during Key ON Engine OFF (KOEO) or Key ON Engine Running (KOER) self-test.

Now when the signal on is more or less than the expected calibrated range, then the PCM would set the P0663 fault code.

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

• Some quirks in the fuel injector control module
• Malfunction in the engine control module
• Valve might start contaminating
• Wiring issue like chafed, cracked, corroded, etc
• Electrical connector might be broken
• Intake manifold tuning valve might have some faults
• There can be some broken valve parts
• Issue of stuck valve

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

A mechanic will diagnose the P0663 code using an OBD-II scanner along with some visual inspections. 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 P0663 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 P0663 Code

• The technicians should avoid the common mistake of repairing symptoms and stored codes that come about as a reaction to the P0663 trouble code by utilizing downloaded freeze frame data to treat codes in the order they occurred. This, in turn, can increase the likelihood that a P0663 trouble code is successfully repaired
