The fault code P248C is related to the cooling fan system of the automobile. The diagnosis of this code involves checking the wiring, connectors, and the cooling fan control module.

The estimated repair time for this fault code is 1.0 hour. The fixing cost of this fault code depends on the hourly rate charged by the auto repair shop, which is usually between $75 and $150 per hour.

Other factors that may influence the fixing cost include the severity of the problem, the type of vehicle, and the availability of replacement parts.

The P248C fault code is related to the reductant heater in an automobile. Reductant can freeze at temperatures below -11°C (12°F), so there are two reductant heaters in the reductant tank. The Engine Control Module (ECM) monitors the reductant temperature and activates a defrost strategy if it determines that the reductant may be frozen.

The P248C code is set when there is greater than a 3 V difference between battery voltage and reductant line heater voltage.

What are the possible causes of the automobile fault code P248C?

If you see the engine light on or service engine soon warning light, it could be due to the P248C fault code. This code is usually 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, 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 P248C fault code in my automobile?
