Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Low Bank 2

Where it lives

For P207C, the circuit described runs through the sensor. The description of P207C puts it on bank 2.

Check these first

• A short to ground on the bank 2 IMT valve position sensor signal wire
• A failed bank 2 IMT valve position sensor
• A corroded position sensor connector pulling the signal low
• A bank 2 IMT valve stuck outside the sensor's travel

What to do next

1. Read the bank 2 IMT valve position sensor on a scan tool
2. Test the position sensor signal wire for a short to ground
3. Inspect the position sensor connector for corrosion
4. Check the bank 2 IMT valve travel
5. Replace the bank 2 IMT valve position sensor if the circuit tests good
6. Clear the code and retest
