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

Where it lives

For P207B, start at the sensor the description names. The description of P207B puts it on bank 2.

Check these first

• A bank 2 IMT valve position sensor reading outside its range
• A bank 2 IMT valve that will not reach the commanded position
• High resistance in the position sensor circuit
• A failed bank 2 IMT valve position sensor

What to do next

1. Read the bank 2 IMT valve position on a scan tool
2. Command the bank 2 IMT valve and watch the position
3. Test the position sensor circuit for added resistance
4. Inspect the bank 2 IMT valve for a mechanical bind
5. Replace the bank 2 IMT valve position sensor if the circuit tests good
6. Clear the code and retest
