The P207D fault code indicates an issue with the Intake Manifold Tuning (IMT) Valve Position Sensor or Switch Circuit for Bank 2. This system plays a crucial role in optimizing engine performance by adjusting the air intake manifold's configuration based on engine demand. When this fault code is triggered, it suggests that the PCM (Powertrain Control Module) has detected a high voltage or open circuit within the sensor circuit for Bank 2.

What are the symptoms of the P207D code?

Drivers may notice several symptoms when the P207D code is active:

• Check Engine Light illuminated on the dashboard
• Reduced engine performance or power loss
• Decreased fuel efficiency
• Rough idling or stalling
• Engine hesitation during acceleration

What causes the P207D code?

Common causes of the P207D code include:

• Faulty IMT valve position sensor
• Damaged wiring or connectors in the sensor circuit
• Short circuit to power in the sensor circuit
• PCM (Powertrain Control Module) malfunction
• Improper installation after service or repair

How to fix P207D?

To resolve the P207D fault code, follow these steps:

1. Use an OBD-II scanner to confirm the fault code and check for any additional codes that may provide more context.
2. Inspect the wiring and connectors related to the IMT sensor for signs of wear, damage, or corrosion.
3. Test the IMT valve position sensor with a multimeter to ensure it is functioning correctly; replace it if it's faulty.
4. Check for proper installation of the IMT valve and associated components after any previous repairs.
5. Clear the fault codes and take the vehicle for a test drive to verify if the problem is resolved; if the code reappears, further diagnostics may be needed.
