The automobile fault code P2448 indicates a problem with the secondary air injection system. The estimated repair time for this issue is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the problem, the type of vehicle, and the location of the repair shop. It is important to address this issue promptly to avoid further damage to the vehicle and potential safety hazards.

The P2448 code is related to the secondary air injection system in a vehicle. This system delivers outside air into the exhaust system to reduce emissions.

The code is set when the actual airflow is higher than the model airflow during the first 20 seconds of a cold start. It specifically refers to high air flow in bank 1 of the system. This fault code can cause increased emissions and may lead to a failed emissions test.

It is important to have this issue diagnosed and repaired by a qualified mechanic.

What are the possible causes of the automobile fault code P2448?

If you see the engine light on or the service engine soon warning light, it could be due to the P2448 fault code. This code is usually caused by a leak in the secondary air system, a faulty air flow sensor, or a poor electrical connection in the air flow sensor circuit. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or corroded connector pins.
