NOTE: The fault indicates that the DEF pump speed is low compared to DEF quantity delivered. The CEL lamp will remain on until the fault is resolved. NOTE: If code 3364-xx present, fix that first. PROBABLE CAUSES:1. Check all DEF supply lines for damage or leaks.2. DEF tank is contaminated with gas, diesel, water, etc…3. Doser valve failure.4. DEF pump.5. DEF pump connection/harness.

NOTE: The fault indicates the high idle regeneration (HIR) was aborted due to diesel oxidation catalyst (DOC) inlet temperature not reaching the minimum of 270°C (518°F) to initiate dosing during an HIR. The malfunction indicator lamp (MIL) will remain on until the fault is resolved or a successful regeneration is complete. DESCRIPTION:DOC Inlet temperature out of range low. MONITORED PARAMETER:DOC temperature TYPICAL ENABLING CONDITIONS:Regeneration MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:Two seconds DASH LAMPS:MIL ENGINE REACTION:None VERIFICATION:Parked regen NOTE: If codes 3242-8 or 3242-20 present, fix those first. PROBABLE CAUSES:1. DOC inlet temperature sensor.2. DOC inlet temperature...
