Turbocharger/Supercharger Boost Sensor D Circuit Range/Performance

Where it lives

For P2CD7, start at the sensor the description names.

Check these first

• A boost sensor D reading outside its expected range
• An intermittent connection at boost sensor D
• A sensor D that drifts as boost rises
• A boost leak skewing the sensor D reading

What to do next

1. Read boost sensor D on a scan tool
2. Compare sensor D to the commanded boost
3. Check the sensor D connector for an intermittent fit
4. Smoke test the charge pipes for a boost leak
5. Replace boost sensor D if its output stays skewed
6. Clear the code and retest
