Code P0137 2019 Honda CR-V Description

The Secondary Heated Oxygen Sensor (Secondary HO2S or Sensor 2) is a component in your vehicle's exhaust system that detects oxygen levels in the exhaust gas. It then converts this information into electrical signals. If the sensor's output voltage remains steady at a specified value for a certain duration, the vehicle's onboard computer, known as the Powertrain Control Module (PCM), identifies this as a potential problem. In response, the PCM stores a Diagnostic Trouble Code (DTC) to indicate the issue for diagnostic purposes. This system helps ensure the vehicle's emissions control system is functioning correctly, contributing to optimal engine performance and emissions reduction.
