Diagnosis & fix steps

Intake Manifold Pressure Data Erratic. LOGIC: The MAP (Boost) sensor reading does not match the Barometric pressure or RPM mapping. ACTION: 1. Inspect for cracked intercooler hoses. 2. Check the sensor for oil/soot clogging. 3. Verify turbo wastegate movement. FIX: Replace Boost Pressure Sensor or repair leaking intake plumbing.

These sensors often get "sludged" with EGR soot. Before replacing, clean the sensor tip with electrical cleaner and clear the manifold port with a small pick.
