The P249E automobile fault code is a common issue that triggers the Engine Light ON or Service Engine Soon Warning Light.

It can be caused by various factors such as exhaust leaks, fuel contamination, faulty Diesel Particulate Filter (DPF), faulty NOx Sensor, Diesel Exhaust Fluid, or faulty Selective Catalyst Reduction (SCR) Catalyst. The importance of repairing this issue lies in the fact that it can lead to reduced engine performance and increased emissions.

The repair difficulty is moderate, and the fix involves visually inspecting the related wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins. The repair time is estimated to be around 1.0 hour.

It is essential to interpret the fault code correctly to identify the root cause of the issue and fix it effectively.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p249e fault code.

Here are the symptoms to look out for:

  • The P249E fault code in automobiles can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, decreased fuel efficiency, and rough idling.
  • Additionally, the vehicle may experience difficulty starting or stalling while driving.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The automobile fault code P249E can be caused by a variety of factors, including exhaust leaks, fuel contamination, and faulty sensors.

  • The automobile fault code P249E can be caused by several factors.
  • These include exhaust leaks, fuel contamination, a faulty Diesel Particulate Filter (DPF), a faulty NOx sensor, Diesel Exhaust Fluid, and a faulty Selective Catalyst Reduction (SCR) Catalyst.
  • It is important to identify the specific cause of the fault code in order to properly address and fix the issue.

Below are the possible fixes for the automobile fault code: p249e, including inspecting wiring harness, connectors, and damaged components.

  • To fix the automobile fault code p249e, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P249E has an estimated repair time of 1.0 hour. The cost of fixing this fault code is influenced by the repair time.

Most auto repair shops charge between $75 and $150 per hour for their services. Therefore, the fixing cost of P249E will range between $75 and $150, depending on the repair time required.

The P249E code is related to the selective catalytic reduction system in diesel engines.

It indicates that the closed-loop reductant injection control is at its limit. This means that the flow of diesel exhaust fluid or reductant into the exhaust gas stream is too high.

The Engine Control Module (ECM) uses two NOx sensors to control exhaust NOx levels and varies the amount of reductant added by varying the reductant injector duty cycle in response to changes in engine exhaust out NOx levels.

The P249E code can cause increased emissions and reduced fuel efficiency.

What are the possible causes of the P249E automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P249E fault code. This code can be caused by a variety of issues, including exhaust leaks, fuel contamination, a faulty diesel particulate filter (DPF), a faulty NOx sensor, diesel exhaust fluid, or a faulty selective catalyst reduction (SCR) catalyst. To fix this issue, you should check the possible causes listed above and visually inspect the related wiring harness and connectors. Additionally, check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the related wiring harness and connectors to fix the P249E fault code?

If you’re experiencing the P249E fault code, which is indicated by the engine light or service engine soon warning light turning on, there are a few possible causes to consider. These include exhaust leaks, fuel contamination, a faulty diesel particulate filter (DPF), a faulty NOx sensor, issues with diesel exhaust fluid, or a faulty selective catalyst reduction (SCR) catalyst. To fix the issue, start by checking the possible causes listed above. Additionally, visually inspect the related wiring harness and connectors for any damage or issues with broken, bent, pushed out, or corroded connector pins.

Is it necessary to check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins to fix the P249E fault code?

Yes, it is necessary to check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins to fix the P249E fault code. This is because the fault code can be caused by a variety of issues, including exhaust leaks, fuel contamination, faulty DPF, faulty NOx sensor, diesel exhaust fluid, and faulty SCR catalyst. Visually inspecting the related wiring harness and connectors can help identify any damaged components or connector issues that may be contributing to the fault code.
