P0134 2021 Honda CR-V Code - Air/Fuel Ratio Sensor 1 Heater System Malfunction
Quick Answer
The Air/Fuel Ratio (A/F) Sensor (Sensor 1) is activated by warming the element with a heater and by maintaining a steady high temperature to accurately calculate the air/fuel ratio. Common causes include Faulty Air/Fuel Ratio (A/F) Sensor (Sensor 1), A/F Sensor (Sensor 1) harness is open or shorted, A/F Sensor (Sensor 1) 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.
