Intake Air Pressure Measurement System - Multiple Sensor Correlation Bank 1

Where it lives

For P00C7, the description names the sensor as the part involved. The description of P00C7 puts it on bank 1.

Check these first

• A dirty or failed intake air pressure sensor
• A failed manifold pressure or barometric sensor on bank 1
• A vacuum leak on bank 1
• Corroded wiring on the sensor circuits
• A faulty ECM comparing the sensors

What to do next

1. Compare all intake pressure sensor readings on a scan tool
2. Smoke test bank 1 for a vacuum leak
3. Inspect the sensor connectors and wiring for corrosion
4. Clean or replace any sensor that reads off from the rest
5. Check the ECM if all sensors agree but the code stays
6. Clear the code and retest
