Check Engine light on in a Hyundai i30 1.5T-GDI 48V Hybrid

Hello everyone, I own a Hyundai i30, model year 2021, with a 1.5T-GDI 48V hybrid gasoline engine and a mileage of 62,376 km. Yesterday, during the return trip after about 20 km of driving, the check engine light came on. A fault query showed the code P047100. The vehicle drives normally so far, without noticeable changes. Has anyone ever had this problem? I will check the exhaust pressure sensor later to see if there are any problems. Sincerely.

A Hyundai i30 owner reported a check engine light with the fault code P047100, indicating a potential issue with the exhaust pressure sensor. The vehicle is operating normally despite the warning. The suggested solutions include inspecting the sensor and its wiring for damage or loose connections, checking for blockages in the exhaust system, and cleaning the sensor to potentially resolve the issue.

The P0471 code typically relates to the exhaust pressure sensor, which monitors the pressure in the exhaust system. Since you plan to check the sensor, start by inspecting the sensor and its wiring for any visible damage or loose connections. Also, ensure that the exhaust system is not blocked or restricted. If everything looks fine, consider cleaning the sensor to see if that resolves the issue. Let us know how it goes or if you have any further questions!
