FAQs

What is code 146 on Cummins? ›

The code you have is stating the EGR coolant temp sensor data is valid but the temp of the coolant is not within spec.

Fault Code: 1896 EGR Valve Controller - Out of Calibration Printable Version Overview Codes Reason Effect Fault Code: 1896 PID(P): S146 SPN: 2791 FMI: 13/13 Lamp: Amber SRT: The EGR valve has failed the automatic calibration procedure at initial key ON. Possible reduced engine performance.

SPN 2791/FMI 11

Description The Faults Code Sets when the Motor Control Module (MCM) Detects that the Exhaust Gas Recirculation (EGR) Valve Position is Incorrect or a High Coolant Temperature Has Been Detected.

If the SPN 13 FMI 13 code is active, the technician should check the sensor supply voltage and the sensor ground. If the sensor supply voltage is low, the technician should check the power and ground circuits for the sensor. If the sensor ground is open, the technician should check the ground circuit for the sensor.

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.

Denial code 146 is used when the diagnosis provided for the date(s) of service reported is considered invalid. This means that the diagnosis code used does not match the medical condition or symptoms documented in the patient's medical records for the specific date(s) of service.

This fault code means that the turbocharger VGT actuator has failed internally.

A 12 valve is a 6 cylinder engine with one intake and one exhaust valve per cylinder. If you are specifically referring to the Cummins 12 valve (sometimes just called a “12 valve”) then it is also of note that it is an entirely mechanical engine. There are no computers.

Fault Code 45 - Speed Sense Fault

The Cummins User / Owner's Manual lists the possible causes of this fault as: loads, generator windings, wire connections, and slip ring corrosion.

[a] If fault code 146 12 is active, inspect the EGR valve flap. If freedom of movement is restricted. remove soot and clean deposits as required. [b] If fault code 146 12 is still active, contact Detroit Diesel Technical Service for instructions to perform a PV2 activation test to verify flap valve functionality.

What is SPN fault code? ›

A Suspect Parameter Number (SPN) is a specific code used in the automotive industry to identify and diagnose faults codes in electronic control units (ECUs) within vehicles. These codes are integral to the CAN Bus system, facilitating precise monitoring and troubleshooting of vehicular systems.

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.

SPN 1243/FMI 14

Description This Fault Code Indicates a Missing Message from the Antilock Brake System (ABS) Module.

An FMI 12 code will tell us that the module or a component that is monitored by this module has gone bad and needs replaced. Data Communication errors are usually going to come from issues in CAN communication.

Page 1. Failure Mode Identifier (FMI) Codes on J1939 data link. The FMI is used along with the SPN to provide specific information that relates to a diagnostic trouble code (DTC). The FMI may indicate that a problem with an electronic circuit or an electronic component has been detected.

Error codes or fault codes is a digital display of signals about the malfunction of the truck systems supplied by the built-in diagnostic module. As they occur,...

DTC P0460 stands for “Fuel Level Sensor “A” Circuit.” This code is triggered when the PCM detects that the input signal from the FLS doesn't fall within the expected range. Code P0460 is commonly caused by a faulty fuel pump, FLS sensor failure, and wiring issues.

Fault Code 46 indicates an electrical fault within the Splitter Solenoid Valve circuit. Note: it has been determined that performing an electrical pre-test is not needed. “F” flashes in gear display. Service light flashes (if equipped).

If Fault Code 145 is Inactive, no problem was found. The intermittent nature of the fault makes it likely that the problem is with the: Driver Interface Device. Secondary shift device request circuit between the Driver Interface Device and 20-Way TCM Vehicle Harness Connector.

A failure to maintain the correct fuel tank pressure results in trouble code P0456. This means that a leak is allowing vapors to escape, either directly from the fuel tank or from related hoses and parts.
