The automobile fault code p248d can be caused by a range of issues, including faulty components and poor electrical connections.

  • The automobile fault code P248D can be caused by a faulty Reductant Line Heater, an open or shorted Reductant Line Heater harness, poor electrical connection in the Reductant Line Heater circuit, a faulty Reductant Pump and Sensor Assembly, and a faulty Reductant Control Module.

To fix the p248d automobile fault code, check the possible causes and inspect related components for damage or corrosion.

  • To fix the automobile fault code p248d, 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 P248D 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 total cost of fixing the P248D fault code will depend on the hourly rate charged by the repair shop and the estimated repair time.

The P248D fault code is related to the reductant system in automobiles. Reductant is a fluid used to reduce harmful emissions from the exhaust. The reductant can freeze at temperatures below -11°C (12°F).

To prevent this, there are two reductant heaters in the tank and supply pipe.

The ECM monitors the reductant temperature and activates a defrost strategy if it may be frozen.

The P248D code is set when there is a voltage difference between battery and reductant line heater.

What are the possible causes of the automobile fault code P248D?

If you see the engine light on or the service engine soon warning light, it could be due to the P248D fault code. This code is usually caused by a faulty reductant line heater, an open or shorted reductant line heater harness, a poor electrical connection in the reductant line heater circuit, a faulty reductant pump and sensor assembly, or a faulty reductant control module. To fix this issue, you should check the possible causes listed above and visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

How can I fix the P248D fault code in my automobile?

If you’re experiencing the P248D fault code in your automobile, which is indicated by the engine light being on, it could be due to a faulty Reductant Line Heater, Reductant Line Heater harness being open or shorted, poor electrical connection in the Reductant Line Heater circuit, a faulty Reductant Pump and Sensor Assembly, or a faulty Reductant Control Module. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

What should I visually inspect to identify the cause of the P248D fault code?

If you’re experiencing the P248D fault code, indicated by the engine light or service engine soon warning light turning on, you should 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 fault code can be caused by a faulty reductant line heater, open or shorted reductant line heater harness, poor electrical connection in the reductant line heater circuit, faulty reductant pump and sensor assembly, or faulty reductant control module. Check the “Possible Causes” listed above for further troubleshooting.

p248d error fault code explained

If you see the Engine Light ON or Service Engine Soon Warning Light with the fault code p248d, check the Reductant Line Heater, harness, and circuit for any damage or poor electrical connection. Also, inspect the Reductant Pump and Sensor Assembly and Control Module. Look for broken, bent, pushed out, or corroded connector’s pins.
