P0138

The P0138 code on a Honda Pilot YF4 (2023-Present) indicates a high voltage reading from the bank 1 oxygen sensor, specifically the O2 sensor located downstream of the catalytic converter. This can lead to poor fuel economy and increased emissions.

The Honda Pilot YF4 (2023-Present) is displaying a P0138 trouble code, which indicates that the oxygen sensor circuit (Bank 1, Sensor 2) has a high voltage signal. This code keeps reappearing, suggesting an underlying issue that has not been resolved.

The P0138 code indicates that the vehicle's powertrain control module (PCM) has detected a high voltage signal from the upstream oxygen sensor (O2 sensor) in your 2016-2022 Honda Pilot YF3.

The P0138 code on a 2016-2022 Honda Pilot YF3 indicates that the Engine Control Module (ECM) has detected a high voltage from the oxygen sensor circuit, specifically the downstream O2 sensor. This suggests a malfunction in the sensor or its circuit.
