P0133 2018 Honda CR-V Code - Air/Fuel Ratio Sensor 1 Malfunction/Slow Response
Quick Answer
The Air/Fuel Ratio (A/F) Sensor (Sensor 1) is responsible for measuring the oxygen concentration in the exhaust gas and providing this information to 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.

Code P0133 2018 Honda CR-V Description
The A/F Sensor (Sensor 1) has a linear signal output in relation to the oxygen concentration. This means that the higher the oxygen concentration in the exhaust gas, the higher the voltage output from the sensor. The PCM converts this voltage output to an air/fuel ratio value, which it then uses to adjust the fuel mixture in the engine.
The PCM also compares the response characteristics of the A/F Sensor (Sensor 1) to a set of predetermined values. If the sensor's response is outside of these predetermined values, the PCM will store a Diagnostic Trouble Code (DTC).
What are the Possible Causes of the DTC P0133 2018 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
How to Fix the DTC P0133 2018 Honda CR-V?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
