Detroit DD16 GHG14 (2014-16) Fault Code: SPN 2623 FMI 8 (CPC) 2 – Channel Accelerator Pedal Signal 2 Missing
Posted by PerDiezel Solutions on
DESCRIPTION:Channel 2 sensor signal failed (high or low). MONITORED PARAMETER:GAS2 TYPICAL ENABLING CONDITIONS:Always on MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:CEL ENGINE REACTION:None VERIFICATION:Key Cycle – Ignition on. NOTE: If any other fault codes, fix those first. PROBABLE CAUSES:1. Accelerator pedal failure.2. Accelerator pedal harness or connector.
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 2630 FMI 16 (MCM) Charge Air Cooler Performance Monitor
Posted by PerDiezel Solutions on
DESCRIPTION:This code sets when the actual charge air cooler (CAC) temperature is higher than the MCM modeled CAC temperature. MONITORED PARAMETER:Charge air cooler outlet temperature sensors. TYPICAL ENABLING CONDITIONS:1. Engine speed 1200 to 1950 rpm.2. Engine torque greater than 1000 N·m (737 lb·ft).3. Intake manifold temperature less than 100°C (212°F). MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:10 seconds DASH LAMPS:MIL ENGINE REACTION:None VERIFICATION:Obtain enabling conditions on a chassis dyno or by driving unloaded vehicle for more than 20 seconds. POSSIBLE CAUSES:1. Low vehicle speed with high engine load.2. External CAC restriction (Such as a plow, winter front or dirt) refer...
