Detroit fuel quantity high table of contents
- Fault description and 25% derate
- Monitored parameter and verification
- Intake manifold sensor checks
- EGR delta P voltage test
- DEF dosing valve and regeneration
The monitored parameter is Injector Quantity, enabled during steady-state drive with no regen. Typical duration is 2 minutes, MIL and CEL both illuminate, and the engine reaction is a 25% derate. Verification is a steady engine RPM of 1400-1500 held for two minutes.
The flow clears other codes, checks intake manifold temperature and sensor pins, compares intake manifold pressure to barometric pressure, measures EGR delta P voltage (0.55-0.83 volts, pin 109), inspects the EGR and exhaust systems, and leak-checks the Charge Air Cooler. On this EPA10 build the closing steps disconnect the DEF metering unit dosing valve (disregarding SPN 3361/5) and run a high idle regeneration.
Applicable truck models
This EPA10 guide applies to Detroit DD13, DD15 and DD16 engines. The EGR cooler procedure differs between the DD13 and the DD15/DD16, and the closing steps address the DEF metering unit, per Power Service Literature. For OEM details, visit Detroit’s official website.
Who needs this Detroit fuel quantity high manual
Technicians servicing EPA10 DD Series engines with an excess-fueling derate use this Detroit manual to isolate an intake, EGR or charge-air fault from a DEF dosing issue. The guide follows the factory decision-tree troubleshooting format.
