Detroit DD13 GHG14 (2014-16) Fault Code: SPN 3242 FMI 20 (ACM) Diesel| ⛽ Diezel365

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.

NOTE: If 3242-3, 3242-4, 3242-8, 3250-3, 3250-4, or 3250-8 present, fix those first.

PROBABLE CAUSES:1. Compare DOC inlet, DOC outlet, and DPF outlet. They should be wihin 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.
