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.

NOTE: High load operation in high ambient temperatures. No action is necessary; this is a “silent” fault where the fan will be turned on. This fault is a concern only if the fan-on times are excessive but coolant temperatures are in the normal operating range. PROBABLE CAUSES:1. If 110-0 is active, repair this first.2. Check for EGR exhaust leaks at the EGR valve actuator.3. Remove the actuator cooler lines and fittings, check for kinks/plugs or leaks.4. EGR valve actuator failure.
