P0138

The P0138 code indicates a high voltage signal from the bank 1 oxygen sensor on a 2017-2023 Genesis G70 IG. This can lead to performance issues and increased emissions.

The P0138 code indicates a high voltage reading from the O2 sensor circuit, specifically for the downstream (post-catalytic converter) oxygen sensor in a Genesis G70 IG (2017-2023). This issue can lead to poor fuel economy and increased emissions.

The P0138 code indicates that the oxygen sensor circuit for Bank 1 Sensor 2 in the 2017-2023 Genesis G70 IG is reading a high voltage signal, which typically suggests an issue with the oxygen sensor or its circuit.

The vehicle, a Genesis G70 (2017-2023), is experiencing a check engine light illumination accompanied by a P0138 error code, indicating a high voltage signal from the oxygen sensor.
