Code P0138 2017 Honda CR-V Description

The P0138 diagnostic trouble code (DTC) for a 2017 Honda CR-V specifically refers to the Secondary Heated Oxygen Sensor 2 Circuit High Voltage. This code indicates that the oxygen sensor located downstream of the catalytic converter is sending a signal to the engine control module (ECM) that shows a higher voltage than normal. The secondary oxygen sensor plays a crucial role in monitoring the efficiency of the catalytic converter by measuring the oxygen levels in the exhaust gases after they have passed through the converter.
