Cummins ISX15 CM2250 (2010-12) Fault Code: 3753 PID: SPN: 3713 FMI: 31 Diesel Particulate Filter Active Regeneration Inhibited Due To System Timeout- Condition Exists - EcuForce Truck (2024)

FAQs

What is the code 3725 on a Cummins x15? ›

This fault code sets when the aftertreatment intake NOx sensor indicates to the ECM that it is not providing valid data and the sensor has failed.

Here's a quick summary on the Cummins fault codes:3497 and 3498: These fault codes indicate that the DEF tank level was low.

Note: This fault code indicates that the aftertreatment diesel particulate filter requires maintenance by preforming a stationary regeneration procedure. This is a maintenance procedure only and is not covered by Cummins warranty.

3714-This fault code is for information only, and indicates that an engine power derate has been implemented in order to make sure that the critical fault codes that are presently active in the ECM are addressed as quickly as possible.

This is a fault code 374 and the reason for the code is the fuel pump controller has detected a calibration error. This is a self check that happens at power up.

The problem is that if you're cruising or running your vehicle at a very low speed, you don't need all of those cylinders, and the vehicle will deactivate the extra cylinders to save you fuel and money. The P3400 code indicates that the deactivation system has somehow malfunctioned.

In cylinder-deactivation mode, the ECM energizes the electronic solenoids, which allows high pressure oil to disengage the pin locking the two rocker arms together.

This is likely a faulty DEF quality sensor.

What is code 418 Cummins? ›

Code 418 , water in fuel.

What Does the Code P0141 Mean? DTC P0141 stands for “Oxygen Sensor Heater Circuit Malfunction (Bank 1, Sensor 2).” It indicates that there's a problem with the heater circuit of engine bank 1's downstream O2 sensor. Your car's PCM tests the oxygen sensors' heater circuits for integrity.

Fault Code 3543-The diesel exhaust fluid quality is not sufficient enough to provide adequate NOx reduction.

It has Active Fault Codes 3868, 4677, 4572. These codes state basically that it has issues with the Diesel Exhaust Fluid Quality, Temperature, and level. All of these codes say it has an abnormal update rate.

Technician: Nich M. Both of these faults indicate an internal failure of the outlet nox sensor. This will be the sensor installed in the exhaust pipe after the aftertreatment system, also the last sensor before the exhaust outlet.

Aside from pump issues this fault code can be anything from air in the fuel, plugged filters, a faulty injector, a faulty fuel pressure relief valve or even an internally failed fuel pump head that shows no physical damage.

An oxides of nitrogen sensor is used to monitor the levels of oxides of nitrogen that a vehicle emits to ensure it is compliant with emissions regulations. Oxides of nitrogen (otherwise known as NOx) are pollutants that have both environmental and health impacts.

The P0513 diagnostic code comes up when there's an issue with your immobilizer key. Immobilizer is a term used to describe a vehicle's anti-theft system, so this issue indicates that a problem exists within the anti-theft process.

Fault code 115 indicates a problem with the engine speed sensor circuit. Troubleshooting steps include inspecting wiring and connectors for damage, checking voltage supply and signal output from the sensor, and verifying the fault code is no longer active after repair.
