P0135 2016 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.

What it means: P0135 2016 Honda CR-V indicates Air/Fuel Ratio Sensor 1 Heater Circuit Malfunction.
Common causes: 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: Moderate - service should be scheduled soon.
Can I drive?: The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0135 2016 Honda CR-V Description

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). It is activated and heats the sensor to stabilize and speed up the detection of oxygen content when the exhaust gas temperature is cold. The PCM monitors the A/F Sensor (Sensor 1) heater output (return check). If the return signals do not meet the command value (for heater activation) for a set time, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
