Turbocharger Interstage Pressure Sensor A Circuit Range/Performance

Where it lives

For P2D22, the description names the sensor as the part involved.

Check these first

• Turbo interstage pressure sensor A reading out of range
• Contamination in the sensor A pressure port
• A restricted interstage pressure passage
• Sensor A calibration drift
• A faulty sensor A connector

What to do next

1. Read interstage pressure sensor A on a scan tool
2. Compare it to the expected boost
3. Clean the sensor A pressure port
4. Inspect the sensor A connector and wiring
5. Replace sensor A if the reading stays skewed
6. Clear the code and retest
