Cummins X15 CM2450 X124B (2018 & Newer) Fault Code: 2692 PID: SPN: 3936 FMI: 2 Aftertreatment 1 Diesel Particulate Filter System- Data Erratic, Intermittent, Or Incorrect - EcuForce Truck (2024)

FAQs

How to fix Cummins fault code 2692? ›

It just indicates that the DPF is not completely plugged. Nich M. With the 2692 and the way that the DPF looks, I would replace it. I would clean the EGR differential pressure sensor ports thoroughly, clean the EGR valve and consider replacing it if the pressure during a regen doesn't come down.

Symptom: Fault Codes 1867 and 2962 Root Cause: Water intrusion caused by exhaust gas recirculation (EGR) temperature sensor water jacket distortion. EGR temperature sensor wires on select chassis were overstretched during EGR temperature sensor installation and wiring harness routing.

Using a code reader tool, connect to the ECM and find the “fault codes” tab. The displayed codes can generally be clicked on one by one. Another option is to select “erase all faults” and then follow the onscreen instructions. At the end of the procedure, the ignition key should be turned off.

The exhaust gas pressure sensor is located above the front section of exhaust manifold and is plumbed into the exhaust manifold between the number 1 and number 2 cylinders, Possible causes for this fault code include: Signal circuit open or shorted to ground, in the engine harness or sensor.

This is an internal error of the particulate matter (PM) sensor and it will need to be replaced.

Codes 6254, 6255, & 3712 are all derated codes that occur when another fault is causing the actual problem. As you can see from the list, the diesel exhaust fluid (DEF) codes are the top 3 most common fault codes if you ignore the derate codes.

SPN is short for suspect parameter number. It identifies which electrical circuit, part or component of your truck isn't working properly. FMI stands for failure mode identifier—this part of the fault code tells you what type of problem your truck has.

The diagnostic trouble code (DTC) P040D means “Exhaust Gas Recirculation Temperature Sensor 'A' Circuit High.” The PCM compares the EGR temperature sensor ”A” readings with values programmed into its memory. If the voltage is too high, it will set the generic code P040D.

A: The ECM Code and/or the SC and DO Options should be stamped on the engine dataplate. If it is unavailable, the ECM Code may be listed on QSOL. If not, the options can be used with an INCAL to determine the correct ECM Code.

Often, the exhaust gas pressure sensor is located at the engine outlet, just before the turbocharger. Sometimes a second sensor is located before the diesel particulate filter. If a third sensor is present, it may be located at the outlet of this emission control device.

What is the code for DPF differential pressure sensor? ›

If the ECU detects that the differential pressure is too high, a P244B will be stored.

Fault Code 329 can result due to one or more of the following: this fault can be caused by bad grounds. High fuel inlet restrictions and/or air in the fuel can set the fault code. Fuel that does not , criteria, specifically density and viscosity, has also been know to set fault code 329.

OBD Code P2692 - Cylinder 7 Injector Data Incompatible

If your diesel powered vehicle has stored a code P2692, it means that the powertrain control module (PCM) is unable to detect the presence and functioning of cylinder 7 fuel injector.

Low fuel pressure at rated speed/load indicates a fuel inlet restriction or a plugged pressure-side fuel filter. Possible causes of this fault code include: A plugged pressure or suction side fuel filter.

The root cause of the 3596 codes is a cracked suction tube in the DEF tank head assembly suction tubes.

Fault Code 295 Barometric Pressure - Data Erratic, Intermittent, or Incorrect.
