P0139 2016 Honda CR-V Code - Secondary Heated Oxygen Sensor 2 Slow Response
Quick Answer
The Secondary Heated Oxygen Sensor (Secondary HO2S (Sensor 2)) detects the oxygen content in the exhaust gas downstream of the three-way catalytic converter (TWC) during stoichiometric air/fuel ratio feedback control. Common causes include Faulty Secondary Heated Oxygen Sensor 2, Secondary Heated Oxygen Sensor 2 harness is open or shorted, Secondary Heated Oxygen Sensor 2 circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.
