P0663 code definition

A P0663 trouble code signals that a fault has been detected by the Powertrain Control Module (PCM) in the intake manifold tuning valve control circuit. This fault can also be detected by one of the other control modules, including the anti-theft control module, anti-lock brake control module, body control module, climate control module, cruise control module, instrument panel control module, proximity alert module, traction control module, transmission control module, and turbo control module.

Related codes that might also be stored in addition to the P0663 trouble code include a P0660, P0661, P0662, P0664, and P0665 trouble codes.

What the P0663 code means

If an error is detected in the intake manifold tuning valve control circuit for engine bank 2, a P0663 trouble code is stored and the Check Engine Light illuminates. Some vehicle models require additional drive cycles with a failure beyond the first before the Check Engine illuminates.

What causes the P0663 code?

Two common causes of a P0663 trouble code is a bad electrical connection and a defective driver in the PCM. Shorted, corroded, or damaged wiring and connectors in the Controller Area Network (CAN) Bus harness can also cause this code, as can loose control module ground straps and broken ground wires. A faulty CAN Bus or fuel injector control module can also cause the storage of this code.

What are the symptoms of the P0663 code?

In addition to causing drivability issues, storage of a P0663 trouble code can cause the engine to idle roughly or stall. Some other signs of a P0663 trouble code include a decrease in the vehicle's fuel economy and poor acceleration.

How does a mechanic diagnose the P0663 code?

Diagnosing a P0663 trouble code requires a mechanic to use an advanced scanner, digital volt/ohmmeter, a specialized scanner, an auxiliary ground cable, and a CAN Bus system wiring diagram. The mechanic should also perform the following diagnostic steps:

  • Visually inspect all wiring, connectors, and components associated with the intake manifold tuning valve control circuit for engine bank 2. The mechanic should look for any loose, corroded, or damaged wiring, connectors, or components.

  • After making the repairs, clear the code and test the system by test driving the vehicle to see if the code returns.

  • Also, the mechanic should download the freeze frame data and any stored trouble codes, as this allows them to repair codes in the order the codes were stored.

*Using a specialized scanner, the mechanic should test all of the pins in the CAN Bus harness. Before doing so, the mechanic should also install some sort of memory saving device.

  • The mechanic should compare their findings to the manufacturer's specifications.

  • In addition, the mechanic should test all of the control module ground circuits for continuity with the battery ground, connecting an auxiliary ground cable to help with the diagnosis.

  • Using a digital volt/ohmmeter and a CAN Bus system wiring diagram, the mechanic needs to test continuity between each individual controller, comparing their findings to the manufacturer's specifications.

  • Additionally, the mechanic should test the PCM to see if the fault lies with a defective driver.

  • Clear the P0663 trouble code and retest the system to see if it returns.

Common mistakes when diagnosing the P0663 code

Mechanics can 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.

How serious is the P0663 code?

A P0663 trouble code should be addressed as soon as it is stored. This helps the vehicle owner to avoid the more serious problems often associated with the code, such as stalling, rough idling, and lowered fuel economy.

What repairs can fix the P0663 code?

Once a mechanic knows what is causing the P0663 trouble code, they can attempt to repair it. Repairing and clearing the code requires the following:

Rigoberto came on time & quickly diagnosed the problem- rats chewed thru wiring near the battery. He wasn’t able to fix it himself bc of parts, but gave me recommendations on where to go & how to not have the dealership sell me services that are not needed.
