Turbocharger Turbine Inlet Valve Position Sensor Circuit High

Where it lives

For P22D7, the sensor sits on the circuit this code reports. The description of P22D7 reports a fault at the sensor.

Check these first

• The turbine inlet valve position signal wire shorted to voltage
• An open ground at the position sensor
• A failed turbine inlet valve position sensor
• Corrosion or water in the position sensor connector
• An ECM fault on the position sensor input

What to do next

1. Test the position signal wire for a short to voltage
2. Check the position sensor ground for an open
3. Inspect the position sensor connector for corrosion or water
4. Watch turbine inlet valve position live data
5. Replace the position sensor if the signal stays high
6. Clear the code and retest
