Detroit fuel quantity low 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, both MIL and CEL illuminate, and the engine reaction is a 25% derate. Verification is a steady engine RPM of 1400-1500 held for two minutes.
The procedure 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 EGR piping and exhaust for leaks or blockage, and leak-checks the Charge Air Cooler. On this EPA10 build the final steps disconnect the DEF metering unit dosing valve (disregarding SPN 3361/5) and perform a high idle regeneration.
Applicable truck models
This EPA10 guide applies to Detroit DD13, DD15 and DD16 engines. Because it is an EPA10 build, the closing steps address the DEF metering unit before a parked regeneration, per Power Service Literature. For OEM details, see Detroit’s official website.
Who needs this Detroit fuel quantity low manual
Technicians servicing EPA10 DD Series engines with a low-fueling derate use this Detroit manual to separate an intake or EGR fault from a DEF dosing issue before parts are replaced. The guide follows the factory decision-tree troubleshooting format.
