Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3242 FMI 8 (ACM) Diesel Oxidation Catalyst Inlet Temperature – Signal Spike
Posted by PerDiezel Solutions on
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.
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3246 FMI 0 (ACM) Diesel Particulate Filter Outlet Temperature – Very High
Posted by PerDiezel Solutions on
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...

NOTE: Please see the step by step troubleshooting procedures for this specific code. PROBABLE CAUSES:1. DPF outlet temperature sensor.2. DPF outlet temperature sensor connector/harness.
Detroit DD16 GHG14 (2014-16) Fault Code: SPN 3246 FMI 21 (ACM) Diesel Particulate Filter Outlet Temperature Sensor – Not Plausible
Posted by PerDiezel Solutions on
NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE: If codes 3246-3, 3242-3, 3250-3 or 1172-3 active, fix those first. PROBABLE CAUSES:1. Wiring between the turbocharger compressor inlet temperature and the 120-pin MCM connection.2. DPF outlet temperature sensor.3. DPF outlet temperature sensor connector/harness.
