NOTE: If codes 441-xx, 1636-xx, 2791-xx, 3563-xx, or 2630-xx are active, fix those first. PROBABLE CAUSES:1. Inspect the EGR and exhaust system for evidence of leaking.2. Delta P sensor.3. Delta P sensor ports.4. Delta P sensor harness/connector.5. Air inlet manifold pressure sensor.6. Air inlet manifold pressure sensor connector/harness.7. Remove the EGR cooler hot pipe, EGR crossover pipe, and the delivery pipe for excessive build up or blockage.8. EGR valve failure.
