Code P0135 2016 Honda CR-V Description

The P0135 diagnostic trouble code (DTC) refers to an issue with the Air/Fuel Ratio Sensor 1 Heater Circuit in a 2016 Honda CR-V. This sensor is responsible for monitoring the oxygen content in the exhaust gases and sending this information to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. The heater circuit malfunction indicates that the internal heater element in the sensor is not functioning properly, affecting its ability to accurately measure the oxygen levels in the exhaust gases.
