SPN 5357 FMI 16 table of contents
- Fault description and 25% derate
- Monitored parameter and verification
- Intake manifold sensor checks
- EGR delta P voltage test
- Charge Air Cooler leak check
The monitored parameter is Injector Quantity, enabled during steady-state drive with no regen. Typical duration is 2 minutes, both MIL and CEL are on, and the engine reaction is a 25% derate. Verification is a steady engine RPM of 1400-1500 held for two minutes.
The troubleshooting flow first rules out other codes, then checks intake manifold temperature and the temperature/pressure sensors, compares intake manifold pressure to barometric pressure, measures EGR delta P voltage (0.55-0.83 volts on pin 109), inspects the EGR and exhaust systems for leaks or blockage, leak-checks the Charge Air Cooler, and closes with a high idle regeneration.
Applicable truck models
This guide applies to Detroit DD13, DD15 and DD16 engines under EPA 2007 / GHG14. EGR cooler removal differs between the DD13 and the DD15/DD16, and each step references Power Service Literature. For OEM specifications and dealer locations, visit Detroit’s official website.
Who needs this SPN 5357 FMI 16 manual
Diesel technicians investigating a 25% derate with excess fueling on DD Series engines use this document to work the intake, EGR and charge-air path methodically before condemning a sensor or the EGR cooler. The guide follows the factory decision-tree troubleshooting format.
