P0138

The P0138 code indicates a high voltage signal from the oxygen sensor (O2 sensor) in the exhaust system of a Volkswagen Golf MK6 (2009-2014). This typically points to a malfunctioning sensor or an issue with the electrical circuit related to the sensor.

The P0138 code indicates a high voltage signal from the oxygen sensor located after the catalytic converter in a 2013-2020 Volkswagen Golf (Seventh Generation). This typically suggests an issue with the sensor or the related electrical circuits.

The P0138 code indicates a high voltage signal from the upstream oxygen sensor in a 2015-2019 Volkswagen Golf MK7, which may lead to poor engine performance and increased emissions.

The P0138 code indicates a high voltage signal from the oxygen sensor circuit in your Volkswagen Golf MK7.5 (2020-Present), specifically relating to the downstream oxygen sensor (Sensor 2).

The P0138 code indicates that the oxygen sensor circuit for Bank 1 Sensor 2 is experiencing a high voltage issue, which can affect the vehicle's emissions and fuel efficiency. This issue typically occurs in Volkswagen Golf MK7 models from 2015 to 2019.

The Volkswagen Golf MK7 (2015-2019) is displaying a P0138 trouble code, indicating an issue with the oxygen sensor circuit.
