P0135 2018 Honda CR-V Code - Air/Fuel Ratio Sensor 1 Heater Circuit Malfunction
Quick Answer
A heater for the sensor element is embedded in the Air/Fuel Ratio (A/F) Sensor (Sensor 1), and it is controlled by the Powertrain Control Module (PCM). 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.
