NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE: If any battery voltage codes present, first those first. If code 625-9 active, fix that before proceding as well. PROBABLE CAUSES:1. CPC recently programmed incorrectly.2. Another computer on the truck is the cause of the problems (ABS, Transmission, etc…).

NOTE: This code sets when the motor control module (MCM) detects very high charge air and air intake manifold temperatures. DESCRIPTION:Charge air cooler (CAC) low efficiency. MONITORED PARAMETER:Intake manifold and charge air cooler outlet temperature sensors. TYPICAL ENABLING CONDITIONS:Coolant temperature is above 65°C (149°F). MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:10 DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 10% VERIFICATION:Road test the vehicle with coolant temperature above 65°C (149°F). NOTE: The intake air temperature and charger air cooler temperature can increase if the vehicle is driven on steep inclines in lower gears. POSSIBLE CAUSES:1. Low vehicle speed with high engine load.2....

DESCRIPTION:Engine air temperature – plausibility fault out of range (low box). MONITORED PARAMETER:Intake manifold and charge air cooler outlet temperature sensors. TYPICAL ENABLING CONDITIONS:1. Start with engine shut off.2. Idle speed less than 900 rpm.3. Coolant temperature greater than 65°C (149°F).4. DPF zone 0. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Once per drive cycle. TYPICAL DURATION:20 DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:1. Start with ignition shut off.2. Start engine.3. Warm up by driving vehicle so that coolant temperature greater than 65°C (149°F).4. Let vehicle idle for greater than 5 min at less than 900 rpm. NOTE: If there are codes present...
