Detroit Diesel

DESCRIPTION:70°C (126°F) difference during non-regeneration mode. MONITORED PARAMETER:Diesel oxidation catalyst (DOC) inlet temperature vs. DOC outlet temperature. TYPICAL ENABLING CONDITIONS:1. Coolant temperature greater than 60°C (140°F).2. Regen not active in the last five minutes. EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:One minute DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Regen inhibit and 10% engine derate. VERIFICATION:Low temperature regen. PROBABLE CAUSES:1. Compare DOC inlet, DOC outlet, and DPF outlet. They should be within 45 degrees of each other.2. DOC inlet temperature sensor.3. DOC inlet temperature sensor connector/harness.4. DOC outlet temperature sensor.5. DOC outlet temperature sensor connector/harness. Detroit DD13 EPA10 (2010-13) Fault Code:...

NOTE: Please see the step by step troubleshooting procedures for this specific code. POSSIBLE CAUSES:1. Turbocharger inlet air temperature sensor.2. Turbocharger inlet air temperature sensor connector/harness.3. DOC inlet temperature sensor.4. DOC inlet temperature sensor connector/harness.

NOTE: This fault indicates the aftertreatment control module (ACM) has detected no temperature shift on the diesel oxidation catalyst (DOC) inlet temperature sensor . The most likely cause is an intermittent wiring concern (poor terminal fit, corrosion, chaffing etc.) NOTE: If codes 3242-3 or 3242-4 active, fix those first. PROBABLE CAUSES:1. DOC inlet temperature sensor.2. DOC inlet temperature sensor connector/harness.

DESCRIPTION:This code sets when the Diesel Particulate Filter (DPF) outlet temperature is greater than 760°C (1400°F) for more that two seconds. MONITORED PARAMETER:DPF Outlet Temperature Sensor. TYPICAL ENABLING CONDITIONS:Always on MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions are met. TYPICAL DURATION:Two seconds DASH LAMPS:1. CEL2. MIL3. SEL ENGINE REACTION:1. 25% Derate.2. Engine Shutdown. VERIFICATION:Parked regeneration POSSIBLE CAUSES:1. Faulty DPF outlet temperature sensor.2. Fluid intrusion into the exhaust.3. Biased input for fuel mapping.4. Incorrect or over-contributing fuel injectors.5. Restricted air filter.6. Incorrect camshaft timing. NOTE: If any other codes are active fix those first. PROBABLE CAUSES:1. DPF outlet temperature sensor.2. DPF...
