P0134 2020 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.

Code P0134 2020 Honda CR-V Description
1. When the A/F Sensor (Sensor 1) does not activate for a set time after the A/F sensor (sensor 1) heater is turned on (with high A/F Sensor (Sensor 1) internal resistance), a malfunction of the A/F sensor (sensor 1) heater is detected, and a Diagnostic Trouble Code (DTC) is stored.
2. When the A/F Sensor (Sensor 1) heater cycles ON and OFF for a set time, and the resistance remains high when the heater is ON, a malfunction of the A/F Sensor (Sensor 1) heater is detected, and a DTC is stored.
What are the Possible Causes of the DTC P0134 2020 Honda CR-V?
- 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
