The P249C 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, including exhaust leaks, fuel contamination, faulty Diesel Particulate Filter (DPF), NOx Sensor, Diesel Exhaust Fluid, or Selective Catalyst Reduction (SCR) Catalyst. The importance of repairing this issue lies in preventing further damage to the vehicle’s engine and exhaust system. The repair difficulty is moderate, with a repair time of 1.0.

To fix the issue, one should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or corroded connector pins.

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the p249c fault code.

Here are the symptoms to look out for:

  • The P249C fault code in automobiles can cause several symptoms, including the illumination of the engine light or service engine soon warning light.
  • Other symptoms may include a decrease in engine power, reduced fuel efficiency, and difficulty starting the engine.
  • Additionally, the vehicle may experience rough idling or stalling, and there may be a noticeable decrease in acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe operation on the road.

There are several causes of the automobile fault code p249c, including exhaust leaks, fuel contamination, and faulty DPF.

  • The automobile fault code P249C 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 diagnose and fix the issue.

Below are the possible fixes for the automobile fault code p249c, including a visual inspection of wiring harness and connectors.

  • To fix the automobile fault code p249c, first, check the possible causes listed above.
  • Then, 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 P249C has an estimated repair time of 1.0 hour. The cost of fixing this code varies depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour.

These factors are influential in determining the overall cost of diagnosing and fixing the P249C fault code.

P249C is a fault code related to the Diesel Exhaust Fluid (DEF) system. The DEF system is used to reduce harmful Oxides of Nitrogen (NOx) in the exhaust gas stream. The system requires a storage tank, a pump, an injector, a fluid heater, and a catalyst.

P249C indicates that there is excessive time to enter closed loop reductant injection control. Correct operation of the DEF system is crucial for reducing vehicle exhaust gas emissions.

What are the possible causes of the P249C automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P249C 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 P249C fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to the P249C fault code, there are a few possible causes to consider. These include 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 the issue, start by checking the possible causes listed above. Then, visually inspect the related wiring harness and connectors for any damage or broken, bent, pushed out, or corroded pins.

Is it necessary to check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins to fix the P249C 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 P249C 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.
