Regulatory Fault Ignored - Derate On 5246 (2024)

FAQs

What is the code 5246 on a John Deere engine? ›

5246-- Aftertreatment SCR Operator Inducement - Data Valid But Above Normal Operational Range - Most Severe Level.

The first code is an emissions fault. It is reporting the engine was run with a serious fault or problem with the emissions and this triggers the 5246-0 Aftertreatment SCR Operator Inducement Severity : High - most severe (3)This code is a Level 3 inducement associated with an emission activated fault.

The 5246 fault is just an inducement fault. This means that derates are active presently. Now on your nox readings, How far into the regen was this noted? What did the inlet say?

This code is known as a regulatory fault. It is based on another fault and comes active to show that there is a derate. There is another code related to the aftertreatment system that is causing this code. This code will pertain to an issue with the SCR system.

Engine derating is the reduction of an engine's output due to less-than-ideal operating conditions. Derating sometimes is done intentionally when you want to prolong the engine's life and avoid substantial wear or damage.

A common emissions code seen in the field, a P0420 trouble code indicates that the catalytic converter isn't functioning efficiently.

The P0420 code signals a low catalyst system efficiency. This code suggests that the oxygen levels are below the desired threshold (Bank 1), which most often results from problems with your car's exhaust or fuel systems.

If the timing light is flashing red or you are receiving a "Cat sensor fault" notification in the Whisker app, this indicates the cat sensor has been continuously activated for 30 minutes or more, either by a cat that won't leave the globe or by too much weight in the unit.

Driving with a derate may cause permanent damage to your engine or emission system. Be cautious when driving with an active derate and get into a service shop as soon as you can to figure out what the issue is.

What is the code 5246 on a caterpillar? ›

This code is an inducement associated with an emissions system fault. The engine is derated, limited to low idle, and can experience 5 minute rolling shutdowns. An E1389 or 5246 code will come active with another associated code in the “Selective Catalyst Reduction System” ECM.

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.

The purpose of SCR inducement codes are to alert the operator that the emissions system requires service or repair. Inducements can be engine derates, vehicle speed limits, system lockouts, or any other action intended to prompt the operator in performing repair or maintenance on the emissions control system.

The sensor is just above the transmission filter housing at the front of the power quad, there's two together the lower one is for filter restriction. If it's an original sensor you'll need a short 30mm spanner (these sensors are prone to failure) the new sensors are 15mm.

The definition of code P061A is “Internal Control Module Torque Performance.” This code means that your powertrain control module (PCM) has detected some kind of performance error in the engine torque monitoring system or that another individual module, such as your engine control module (ECM), transmission control ...

What Is the P1762 Code? Can I Still Drive? The P1762 code indicates that there may be an issue with your vehicle's overdrive band. It's a code that's generally specific to Ford vehicles, often vehicles that are intended for off-roading.
